From class DialogFragment

`Int`	`STYLE_NORMAL` Style for `setStyle(int, int)`: a basic, normal dialog.
`Int`	`STYLE_NO_FRAME` Style for `setStyle(int, int)`: don't draw any frame at all; the view hierarchy returned by `onCreateView` is entirely responsible for drawing the dialog.
`Int`	`STYLE_NO_INPUT` Style for `setStyle(int, int)`: like `STYLE_NO_FRAME`, but also disables all input to the dialog. The user can not touch it, and its window will not receive input focus.
`Int`	`STYLE_NO_TITLE` Style for `setStyle(int, int)`: don't include a title area.

Inherited functions

From class DialogFragment

`Unit`	`dismiss()` Dismiss the fragment and its dialog. If the fragment was added to the back stack, all back stack state up to and including this entry will be popped. Otherwise, a new transaction will be committed to remove the fragment.
`Unit`	`dismissAllowingStateLoss()` Version of `dismiss()` that uses `FragmentTransaction.commitAllowingStateLoss()`. See linked documentation for further details.
`Dialog?`	`getDialog()` Return the `Dialog` this fragment is currently controlling.
`Boolean`	`getShowsDialog()` Return the current value of `setShowsDialog(boolean)`.
`Int`	`getTheme()`
`Boolean`	`isCancelable()` Return the current value of `setCancelable(boolean)`.
`Unit`	`onAttach(@NonNull context: Context)`
`Unit`	`onCancel(@NonNull dialog: DialogInterface)`
`Unit`	`onDestroyView()` Remove dialog.
`Unit`	`onDetach()`
`LayoutInflater`	`onGetLayoutInflater(@Nullable savedInstanceState: Bundle?)` Returns the LayoutInflater used to inflate Views of this Fragment. The default implementation will throw an exception if the Fragment is not attached. If this is called from within `onCreateDialog(Bundle)`, the layout inflater from `Fragment#onGetLayoutInflater(Bundle)`, without the dialog theme, will be returned.
`Unit`	`onStart()`
`Unit`	`onStop()`
`Unit`	`onViewStateRestored(@Nullable savedInstanceState: Bundle?)`
`Dialog`	`requireDialog()` Return the `Dialog` this fragment is currently controlling.
`Unit`	`setCancelable(cancelable: Boolean)` Control whether the shown Dialog is cancelable. Use this instead of directly calling `Dialog.setCancelable(boolean)`, because DialogFragment needs to change its behavior based on this.
`Unit`	`setShowsDialog(showsDialog: Boolean)` Controls whether this fragment should be shown in a dialog. If not set, no Dialog will be created and the fragment's view hierarchy will thus not be added to it. This allows you to instead use it as a normal fragment (embedded inside of its activity). This is normally set for you based on whether the fragment is associated with a container view ID passed to `FragmentTransaction.add(int, Fragment)`. If the fragment was added with a container, setShowsDialog will be initialized to false; otherwise, it will be true. If calling this manually, it should be called in `onCreate(Bundle)` as calling it any later will have no effect.
`Unit`	`setStyle(style: Int, @StyleRes theme: Int)` Call to customize the basic appearance and behavior of the fragment's dialog. This can be used for some common dialog behaviors, taking care of selecting flags, theme, and other options for you. The same effect can be achieve by manually setting Dialog and Window attributes yourself. Calling this after the fragment's Dialog is created will have no effect.
`Unit`	`show(@NonNull manager: FragmentManager, @Nullable tag: String?)` Display the dialog, adding the fragment to the given FragmentManager. This is a convenience for explicitly creating a transaction, adding the fragment to it with the given tag, and `committing` it. This does not add the transaction to the fragment back stack. When the fragment is dismissed, a new transaction will be executed to remove it from the activity.
`Int`	`show(@NonNull transaction: FragmentTransaction, @Nullable tag: String?)` Display the dialog, adding the fragment using an existing transaction and then `committing` the transaction.
`Unit`	`showNow(@NonNull manager: FragmentManager, @Nullable tag: String?)` Display the dialog, immediately adding the fragment to the given FragmentManager. This is a convenience for explicitly creating a transaction, adding the fragment to it with the given tag, and calling `FragmentTransaction#commitNow()`. This does not add the transaction to the fragment back stack. When the fragment is dismissed, a new transaction will be executed to remove it from the activity.

From class Fragment

`Unit`	`dump(@NonNull prefix: String, @Nullable fd: FileDescriptor?, @NonNull writer: PrintWriter, @Nullable args: Array<String!>?)` Print the Fragments's state into the given stream.
`Boolean`	`equals(@Nullable other: Any?)` Subclasses can not override equals().
`FragmentActivity?`	`getActivity()` Return the `FragmentActivity` this fragment is currently associated with. May return `null` if the fragment is associated with a `Context` instead.
`Boolean`	`getAllowEnterTransitionOverlap()` Returns whether the the exit transition and enter transition overlap or not. When true, the enter transition will start as soon as possible. When false, the enter transition will wait until the exit transition completes before starting.
`Boolean`	`getAllowReturnTransitionOverlap()` Returns whether the the return transition and reenter transition overlap or not. When true, the reenter transition will start as soon as possible. When false, the reenter transition will wait until the return transition completes before starting.
`Bundle?`	`getArguments()` Return the arguments supplied when the fragment was instantiated, if any.
`FragmentManager`	`getChildFragmentManager()` Return a private FragmentManager for placing and managing Fragments inside of this Fragment.
`Context?`	`getContext()` Return the `Context` this fragment is currently associated with.
`ViewModelProvider.Factory`	`getDefaultViewModelProviderFactory()` Returns the default `ViewModelProvider.Factory` that should be used when no custom `Factory` is provided to the `ViewModelProvider` constructors. The `Fragment's arguments` when this is first called will be used as the defaults to any `androidx.lifecycle.SavedStateHandle` passed to a view model created using this factory.
`Any?`	`getEnterTransition()` Returns the Transition that will be used to move Views into the initial scene. The entering Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as entering is governed by changing visibility from `View#INVISIBLE` to `View#VISIBLE`.
`Any?`	`getExitTransition()` Returns the Transition that will be used to move Views out of the scene when the fragment is removed, hidden, or detached when not popping the back stack. The exiting Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as exiting is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If transition is null, the views will remain unaffected.
`FragmentManager?`	`getFragmentManager()` Return the FragmentManager for interacting with fragments associated with this fragment's activity. Note that this will be non-null slightly before `getActivity()`, during the time from when the fragment is placed in a `FragmentTransaction` until it is committed and attached to its activity. If this Fragment is a child of another Fragment, the FragmentManager returned here will be the parent's `getChildFragmentManager()`.
`Any?`	`getHost()` Return the host object of this fragment. May return `null` if the fragment isn't currently being hosted.
`Int`	`getId()` Return the identifier this fragment is known by. This is either the android:id value supplied in a layout or the container view ID supplied when adding the fragment.
`LayoutInflater`	`getLayoutInflater()` Returns the cached LayoutInflater used to inflate Views of this Fragment. If `onGetLayoutInflater(Bundle)` has not been called `onGetLayoutInflater(Bundle)` will be called with a `null` argument and that value will be cached. The cached LayoutInflater will be replaced immediately prior to `onCreateView(LayoutInflater, ViewGroup, Bundle)` and cleared immediately after `onDetach()`.
`Lifecycle`	`getLifecycle()` Returns the Lifecycle of the provider. Overriding this method is no longer supported and this method will be made `final` in a future version of Fragment.
`LoaderManager`	`getLoaderManager()` Return the LoaderManager for this fragment.
`Fragment?`	`getParentFragment()` Returns the parent Fragment containing this Fragment. If this Fragment is attached directly to an Activity, returns null.
`FragmentManager`	`getParentFragmentManager()` Return the FragmentManager for interacting with fragments associated with this fragment's activity. Note that this will available slightly before `getActivity()`, during the time from when the fragment is placed in a `FragmentTransaction` until it is committed and attached to its activity. If this Fragment is a child of another Fragment, the FragmentManager returned here will be the parent's `getChildFragmentManager()`.
`Any?`	`getReenterTransition()` Returns the Transition that will be used to move Views in to the scene when returning due to popping a back stack. The entering Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as exiting is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If nothing is set, the default will be to use the same transition as `getExitTransition()`.
`Resources`	`getResources()` Return `requireActivity().getResources()`.
`Boolean`	`getRetainInstance()` Returns `true` if this fragment instance's state will be retained across configuration changes, and `false` if it will not.
`Any?`	`getReturnTransition()` Returns the Transition that will be used to move Views out of the scene when the Fragment is preparing to be removed, hidden, or detached because of popping the back stack. The exiting Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as entering is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If nothing is set, the default will be to use the same transition as `getEnterTransition()`.
`SavedStateRegistry`	`getSavedStateRegistry()`
`Any?`	`getSharedElementEnterTransition()` Returns the Transition that will be used for shared elements transferred into the content Scene. Typical Transitions will affect size and location, such as `android.transition.ChangeBounds`. A null value will cause transferred shared elements to blink to the final position.
`Any?`	`getSharedElementReturnTransition()` Return the Transition that will be used for shared elements transferred back during a pop of the back stack. This Transition acts in the leaving Fragment. Typical Transitions will affect size and location, such as `android.transition.ChangeBounds`. A null value will cause transferred shared elements to blink to the final position. If no value is set, the default will be to use the same value as `setSharedElementEnterTransition(Object)`.
`String`	`getString(@StringRes resId: Int)` Return a localized string from the application's package's default string table.
`String`	`getString(@StringRes resId: Int, @Nullable vararg formatArgs: Any!)` Return a localized formatted string from the application's package's default string table, substituting the format arguments as defined in `java.util.Formatter` and `java.lang.String#format`.
`String?`	`getTag()` Get the tag name of the fragment, if specified.
`Fragment?`	`getTargetFragment()` Return the target fragment set by `setTargetFragment`.
`Int`	`getTargetRequestCode()` Return the target request code set by `setTargetFragment`.
`CharSequence`	`getText(@StringRes resId: Int)` Return a localized, styled CharSequence from the application's package's default string table.
`Boolean`	`getUserVisibleHint()`
`View?`	`getView()` Get the root view for the fragment's layout (the one returned by `onCreateView`), if provided.
`LifecycleOwner`	`getViewLifecycleOwner()` Get a `LifecycleOwner` that represents the `Fragment's View` lifecycle. In most cases, this mirrors the lifecycle of the Fragment itself, but in cases of `detached` Fragments, the lifecycle of the Fragment can be considerably longer than the lifecycle of the View itself. Namely, the lifecycle of the Fragment's View is: `created` after `onViewStateRestored(Bundle)` `started` after `onStart()` `resumed` after `onResume()` `paused` before `onPause()` `stopped` before `onStop()` `destroyed` before `onDestroyView()` The first method where it is safe to access the view lifecycle is `onCreateView(LayoutInflater, ViewGroup, Bundle)` under the condition that you must return a non-null view (an IllegalStateException will be thrown if you access the view lifecycle but don't return a non-null view). The view lifecycle remains valid through the call to `onDestroyView()`, after which `getView()` will return null, the view lifecycle will be destroyed, and this method will throw an IllegalStateException. Consider using `getViewLifecycleOwnerLiveData()` or `FragmentTransaction#runOnCommit(Runnable)` to receive a callback for when the Fragment's view lifecycle is available. This should only be called on the main thread. Overriding this method is no longer supported and this method will be made `final` in a future version of Fragment.
`LiveData<LifecycleOwner!>`	`getViewLifecycleOwnerLiveData()` Retrieve a `LiveData` which allows you to observe the `lifecycle of the Fragment's View`. This will be set to the new `LifecycleOwner` after `onCreateView` returns a non-null View and will set to null after `onDestroyView()`. Overriding this method is no longer supported and this method will be made `final` in a future version of Fragment.
`ViewModelStore`	`getViewModelStore()` Returns the `ViewModelStore` associated with this Fragment Overriding this method is no longer supported and this method will be made `final` in a future version of Fragment.
`Int`	`hashCode()` Subclasses can not override hashCode().
`Fragment`	`instantiate(@NonNull context: Context, @NonNull fname: String)` Like `instantiate(Context, String, Bundle)` but with a null argument Bundle.
`Fragment`	`instantiate(@NonNull context: Context, @NonNull fname: String, @Nullable args: Bundle?)` Create a new instance of a Fragment with the given class name. This is the same as calling its empty constructor, setting the `ClassLoader` on the supplied arguments, then calling `setArguments(Bundle)`.
`Boolean`	`isAdded()` Return true if the fragment is currently added to its activity.
`Boolean`	`isDetached()` Return true if the fragment has been explicitly detached from the UI. That is, `FragmentTransaction.detach(Fragment)` has been used on it.
`Boolean`	`isHidden()` Return true if the fragment has been hidden. By default fragments are shown. You can find out about changes to this state with `onHiddenChanged`. Note that the hidden state is orthogonal to other states -- that is, to be visible to the user, a fragment must be both started and not hidden.
`Boolean`	`isInLayout()` Return true if the layout is included as part of an activity view hierarchy via the <fragment> tag. This will always be true when fragments are created through the <fragment> tag, except in the case where an old fragment is restored from a previous state and it does not appear in the layout of the current state.
`Boolean`	`isRemoving()` Return true if this fragment is currently being removed from its activity. This is not whether its activity is finishing, but rather whether it is in the process of being removed from its activity.
`Boolean`	`isResumed()` Return true if the fragment is in the resumed state. This is true for the duration of `onResume()` and `onPause()` as well.
`Boolean`	`isStateSaved()` Returns true if this fragment is added and its state has already been saved by its host. Any operations that would change saved state should not be performed if this method returns true, and some operations such as `setArguments(Bundle)` will fail.
`Boolean`	`isVisible()` Return true if the fragment is currently visible to the user. This means it: (1) has been added, (2) has its view attached to the window, and (3) is not hidden.
`Unit`	`onActivityCreated(@Nullable savedInstanceState: Bundle?)` Called when the fragment's activity has been created and this fragment's view hierarchy instantiated. It can be used to do final initialization once these pieces are in place, such as retrieving views or restoring state. It is also useful for fragments that use `setRetainInstance(boolean)` to retain their instance, as this callback tells the fragment when it is fully associated with the new activity instance. This is called after `onCreateView` and before `onViewStateRestored(Bundle)`.
`Unit`	`onActivityResult(requestCode: Int, resultCode: Int, @Nullable data: Intent?)` Receive the result from a previous call to `startActivityForResult(Intent, int)`. This follows the related Activity API as described there in `Activity#onActivityResult(int, int, Intent)`.
`Unit`	`onAttach(@NonNull activity: Activity)` Called when a fragment is first attached to its activity. `onCreate(Bundle)` will be called after this.
`Unit`	`onAttachFragment(@NonNull childFragment: Fragment)` Called when a fragment is attached as a child of this fragment. This is called after the attached fragment's `onAttach` and before the attached fragment's `onCreate` if the fragment has not yet had a previous call to `onCreate`.
`Unit`	`onConfigurationChanged(@NonNull newConfig: Configuration)`
`Boolean`	`onContextItemSelected(@NonNull item: MenuItem)` This hook is called whenever an item in a context menu is selected. The default implementation simply returns false to have the normal processing happen (calling the item's Runnable or sending a message to its Handler as appropriate). You can use this method for any items for which you would like to do processing without those other facilities. Use `MenuItem#getMenuInfo()` to get extra information set by the View that added this menu item. Derived classes should call through to the base class for it to perform the default menu handling.
`Animation?`	`onCreateAnimation(transit: Int, enter: Boolean, nextAnim: Int)` Called when a fragment loads an animation. Note that if `FragmentTransaction#setCustomAnimations(int, int)` was called with `Animator` resources instead of `Animation` resources, `nextAnim` will be an animator resource.
`Animator?`	`onCreateAnimator(transit: Int, enter: Boolean, nextAnim: Int)` Called when a fragment loads an animator. This will be called when `onCreateAnimation(int, boolean, int)` returns null. Note that if `FragmentTransaction#setCustomAnimations(int, int)` was called with `Animation` resources instead of `Animator` resources, `nextAnim` will be an animation resource.
`Unit`	`onCreateContextMenu(@NonNull menu: ContextMenu, @NonNull v: View, @Nullable menuInfo: ContextMenuInfo?)` Called when a context menu for the `view` is about to be shown. Unlike `onCreateOptionsMenu`, this will be called every time the context menu is about to be shown and should be populated for the view (or item inside the view for `AdapterView` subclasses, this can be found in the `menuInfo`)). Use `onContextItemSelected(android.view.MenuItem)` to know when an item has been selected. The default implementation calls up to `Activity.onCreateContextMenu`, though you can not call this implementation if you don't want that behavior. It is not safe to hold onto the context menu after this method returns.
`Unit`	`onCreateOptionsMenu(@NonNull menu: Menu, @NonNull inflater: MenuInflater)` Initialize the contents of the Fragment host's standard options menu. You should place your menu items in to menu. For this method to be called, you must have first called `setHasOptionsMenu`. See `Activity.onCreateOptionsMenu` for more information.
`View?`	`onCreateView(@NonNull inflater: LayoutInflater, @Nullable container: ViewGroup?, @Nullable savedInstanceState: Bundle?)` Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null. This will be called between `onCreate(Bundle)` and `onViewCreated(View, Bundle)`. A default View can be returned by calling `Fragment(int)` in your constructor. Otherwise, this method returns null. It is recommended to only inflate the layout in this method and move logic that operates on the returned View to `onViewCreated(View, Bundle)`. If you return a View from here, you will later be called in `onDestroyView` when the view is being released.
`Unit`	`onDestroy()` Called when the fragment is no longer in use. This is called after `onStop()` and before `onDetach()`.
`Unit`	`onDestroyOptionsMenu()` Called when this fragment's option menu items are no longer being included in the overall options menu. Receiving this call means that the menu needed to be rebuilt, but this fragment's items were not included in the newly built menu (its `onCreateOptionsMenu(Menu, MenuInflater)` was not called).
`Unit`	`onHiddenChanged(hidden: Boolean)` Called when the hidden state (as returned by `isHidden()` of the fragment has changed. Fragments start out not hidden; this will be called whenever the fragment changes state from that.
`Unit`	`onInflate(@NonNull context: Context, @NonNull attrs: AttributeSet, @Nullable savedInstanceState: Bundle?)` Called when a fragment is being created as part of a view layout inflation, typically from setting the content view of an activity. This may be called immediately after the fragment is created from a `FragmentContainerView` in a layout file. Note this is before the fragment's `onAttach(Context)` has been called; all you should do here is parse the attributes and save them away. This is called the first time the fragment is inflated. If it is being inflated into a new instance with saved state, this method will not be called a second time for the restored state fragment. Here is a typical implementation of a fragment that can take parameters both through attributes supplied here as well from `getArguments()`: Note that parsing the XML attributes uses a "styleable" resource. The declaration for the styleable used here is: The fragment can then be declared within its activity's content layout through a tag like this: This fragment can also be created dynamically from arguments given at runtime in the arguments Bundle; here is an example of doing so at creation of the containing activity:
`Unit`	`onInflate(@NonNull activity: Activity, @NonNull attrs: AttributeSet, @Nullable savedInstanceState: Bundle?)` Called when a fragment is being created as part of a view layout inflation, typically from setting the content view of an activity.
`Unit`	`onLowMemory()`
`Unit`	`onMultiWindowModeChanged(isInMultiWindowMode: Boolean)` Called when the Fragment's activity changes from fullscreen mode to multi-window mode and visa-versa. This is generally tied to `Activity#onMultiWindowModeChanged` of the containing Activity.
`Boolean`	`onOptionsItemSelected(@NonNull item: MenuItem)` This hook is called whenever an item in your options menu is selected. The default implementation simply returns false to have the normal processing happen (calling the item's Runnable or sending a message to its Handler as appropriate). You can use this method for any items for which you would like to do processing without those other facilities. Derived classes should call through to the base class for it to perform the default menu handling.
`Unit`	`onOptionsMenuClosed(@NonNull menu: Menu)` This hook is called whenever the options menu is being closed (either by the user canceling the menu with the back/menu button, or when an item is selected).
`Unit`	`onPause()` Called when the Fragment is no longer resumed. This is generally tied to `Activity.onPause` of the containing Activity's lifecycle.
`Unit`	`onPictureInPictureModeChanged(isInPictureInPictureMode: Boolean)` Called by the system when the activity changes to and from picture-in-picture mode. This is generally tied to `Activity#onPictureInPictureModeChanged` of the containing Activity.
`Unit`	`onPrepareOptionsMenu(@NonNull menu: Menu)` Prepare the Fragment host's standard options menu to be displayed. This is called right before the menu is shown, every time it is shown. You can use this method to efficiently enable/disable items or otherwise dynamically modify the contents. See `Activity.onPrepareOptionsMenu` for more information.
`Unit`	`onPrimaryNavigationFragmentChanged(isPrimaryNavigationFragment: Boolean)` Callback for when the primary navigation state of this Fragment has changed. This can be the result of the `getParentFragmentManager()` containing FragmentManager} having its primary navigation fragment changed via `androidx.fragment.app.FragmentTransaction#setPrimaryNavigationFragment` or due to the primary navigation fragment changing in a parent FragmentManager.
`Unit`	`onRequestPermissionsResult(requestCode: Int, @NonNull permissions: Array<String!>, @NonNull grantResults: IntArray)` Callback for the result from requesting permissions. This method is invoked for every call on `requestPermissions(String[], int)`. Note: It is possible that the permissions request interaction with the user is interrupted. In this case you will receive empty permissions and results arrays which should be treated as a cancellation.
`Unit`	`onResume()` Called when the fragment is visible to the user and actively running. This is generally tied to `Activity.onResume` of the containing Activity's lifecycle.
`Unit`	`onViewCreated(@NonNull view: View, @Nullable savedInstanceState: Bundle?)` Called immediately after `onCreateView(LayoutInflater, ViewGroup, Bundle)` has returned, but before any saved state has been restored in to the view. This gives subclasses a chance to initialize themselves once they know their view hierarchy has been completely created. The fragment's view hierarchy is not however attached to its parent at this point.
`Unit`	`postponeEnterTransition()` Postpone the entering Fragment transition until `startPostponedEnterTransition()` or `FragmentManager#executePendingTransactions()` has been called. This method gives the Fragment the ability to delay Fragment animations until all data is loaded. Until then, the added, shown, and attached Fragments will be INVISIBLE and removed, hidden, and detached Fragments won't be have their Views removed. The transaction runs when all postponed added Fragments in the transaction have called `startPostponedEnterTransition()`. This method should be called before being added to the FragmentTransaction or in `onCreate(Bundle)`, `onAttach(Context)`, or `onCreateView(LayoutInflater, ViewGroup, Bundle)`}. `startPostponedEnterTransition()` must be called to allow the Fragment to start the transitions. When a FragmentTransaction is started that may affect a postponed FragmentTransaction, based on which containers are in their operations, the postponed FragmentTransaction will have its start triggered. The early triggering may result in faulty or nonexistent animations in the postponed transaction. FragmentTransactions that operate only on independent containers will not interfere with each other's postponement. Calling postponeEnterTransition on Fragments with a null View will not postpone the transition. Likewise, postponement only works if `FragmentTransaction reordering` is enabled.
`Unit`	`postponeEnterTransition(duration: Long, @NonNull timeUnit: TimeUnit)` Postpone the entering Fragment transition for a given amount of time and then call `startPostponedEnterTransition()`. This method gives the Fragment the ability to delay Fragment animations for a given amount of time. Until then, the added, shown, and attached Fragments will be INVISIBLE and removed, hidden, and detached Fragments won't be have their Views removed. The transaction runs when all postponed added Fragments in the transaction have called `startPostponedEnterTransition()`. This method should be called before being added to the FragmentTransaction or in `onCreate(Bundle)`, `onAttach(Context)`, or `onCreateView(LayoutInflater, ViewGroup, Bundle)`}. When a FragmentTransaction is started that may affect a postponed FragmentTransaction, based on which containers are in their operations, the postponed FragmentTransaction will have its start triggered. The early triggering may result in faulty or nonexistent animations in the postponed transaction. FragmentTransactions that operate only on independent containers will not interfere with each other's postponement. Calling postponeEnterTransition on Fragments with a null View will not postpone the transition. Likewise, postponement only works if `FragmentTransaction reordering` is enabled.
`ActivityResultLauncher<I>`	`registerForActivityResult(@NonNull contract: ActivityResultContract<I, O>, @NonNull callback: ActivityResultCallback<O>)` Register a request to `start an activity for result`, designated by the given `contract`. This creates a record in the `registry` associated wit this caller, managing request code, as well as conversions to/from `Intent` under the hood. This must be called unconditionally, as part of initialization path, typically as a field initializer of an Activity or Fragment. If the host of this fragment is an `ActivityResultRegistryOwner` the `ActivityResultRegistry` of the host will be used. Otherwise, this will use the registry of the Fragment's Activity.
`ActivityResultLauncher<I>`	`registerForActivityResult(@NonNull contract: ActivityResultContract<I, O>, @NonNull registry: ActivityResultRegistry, @NonNull callback: ActivityResultCallback<O>)`
`Unit`	`registerForContextMenu(@NonNull view: View)` Registers a context menu to be shown for the given view (multiple views can show the context menu). This method will set the `OnCreateContextMenuListener` on the view to this fragment, so `onCreateContextMenu(ContextMenu, View, ContextMenuInfo)` will be called when it is time to show the context menu.
`Unit`	`requestPermissions(@NonNull permissions: Array<String!>, requestCode: Int)` Requests permissions to be granted to this application. These permissions must be requested in your manifest, they should not be granted to your app, and they should have protection level `#PROTECTION_DANGEROUS dangerous`, regardless whether they are declared by the platform or a third-party app. Normal permissions `android.content.pm.PermissionInfo#PROTECTION_NORMAL` are granted at install time if requested in the manifest. Signature permissions `android.content.pm.PermissionInfo#PROTECTION_SIGNATURE` are granted at install time if requested in the manifest and the signature of your app matches the signature of the app declaring the permissions. If your app does not have the requested permissions the user will be presented with UI for accepting them. After the user has accepted or rejected the requested permissions you will receive a callback on reporting whether the permissions were granted or not. Note that requesting a permission does not guarantee it will be granted and your app should be able to run without having this permission. This method may start an activity allowing the user to choose which permissions to grant and which to reject. Hence, you should be prepared that your activity may be paused and resumed. Further, granting some permissions may require a restart of you application. In such a case, the system will recreate the activity stack before delivering the result to . When checking whether you have a permission you should use . Calling this API for permissions already granted to your app would show UI to the user to decided whether the app can still hold these permissions. This can be useful if the way your app uses the data guarded by the permissions changes significantly. A sample permissions request looks like this: <code><p> private void showContacts() { if (getActivity().checkSelfPermission(Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, PERMISSIONS_REQUEST_READ_CONTACTS); } else { doShowContacts(); } } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { if (requestCode == PERMISSIONS_REQUEST_READ_CONTACTS && grantResults[0] == PackageManager.PERMISSION_GRANTED) { doShowContacts(); } } </p></code>
`FragmentActivity`	`requireActivity()` Return the `FragmentActivity` this fragment is currently associated with.
`Bundle`	`requireArguments()` Return the arguments supplied when the fragment was instantiated.
`Context`	`requireContext()` Return the `Context` this fragment is currently associated with.
`FragmentManager`	`requireFragmentManager()` Return the FragmentManager for interacting with fragments associated with this fragment's activity. Note that this will available slightly before `getActivity()`, during the time from when the fragment is placed in a `FragmentTransaction` until it is committed and attached to its activity. If this Fragment is a child of another Fragment, the FragmentManager returned here will be the parent's `getChildFragmentManager()`.
`Any`	`requireHost()` Return the host object of this fragment.
`Fragment`	`requireParentFragment()` Returns the parent Fragment containing this Fragment.
`View`	`requireView()` Get the root view for the fragment's layout (the one returned by `onCreateView`).
`Unit`	`setAllowEnterTransitionOverlap(allow: Boolean)` Sets whether the the exit transition and enter transition overlap or not. When true, the enter transition will start as soon as possible. When false, the enter transition will wait until the exit transition completes before starting.
`Unit`	`setAllowReturnTransitionOverlap(allow: Boolean)` Sets whether the the return transition and reenter transition overlap or not. When true, the reenter transition will start as soon as possible. When false, the reenter transition will wait until the return transition completes before starting.
`Unit`	`setArguments(@Nullable args: Bundle?)` Supply the construction arguments for this fragment. The arguments supplied here will be retained across fragment destroy and creation. This method cannot be called if the fragment is added to a FragmentManager and if `isStateSaved()` would return true.
`Unit`	`setEnterSharedElementCallback(@Nullable callback: SharedElementCallback?)` When custom transitions are used with Fragments, the enter transition callback is called when this Fragment is attached or detached when not popping the back stack.
`Unit`	`setEnterTransition(@Nullable transition: Any?)` Sets the Transition that will be used to move Views into the initial scene. The entering Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as entering is governed by changing visibility from `View#INVISIBLE` to `View#VISIBLE`. If `transition` is null, entering Views will remain unaffected.
`Unit`	`setExitSharedElementCallback(@Nullable callback: SharedElementCallback?)` When custom transitions are used with Fragments, the exit transition callback is called when this Fragment is attached or detached when popping the back stack.
`Unit`	`setExitTransition(@Nullable transition: Any?)` Sets the Transition that will be used to move Views out of the scene when the fragment is removed, hidden, or detached when not popping the back stack. The exiting Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as exiting is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If transition is null, the views will remain unaffected.
`Unit`	`setHasOptionsMenu(hasMenu: Boolean)` Report that this fragment would like to participate in populating the options menu by receiving a call to `onCreateOptionsMenu` and related methods.
`Unit`	`setInitialSavedState(@Nullable state: Fragment.SavedState?)` Set the initial saved state that this Fragment should restore itself from when first being constructed, as returned by `FragmentManager.saveFragmentInstanceState`.
`Unit`	`setMenuVisibility(menuVisible: Boolean)` Set a hint for whether this fragment's menu should be visible. This is useful if you know that a fragment has been placed in your view hierarchy so that the user can not currently seen it, so any menu items it has should also not be shown.
`Unit`	`setReenterTransition(@Nullable transition: Any?)` Sets the Transition that will be used to move Views in to the scene when returning due to popping a back stack. The entering Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as exiting is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If transition is null, the views will remain unaffected. If nothing is set, the default will be to use the same transition as `getExitTransition()`.
`Unit`	`setRetainInstance(retain: Boolean)` Control whether a fragment instance is retained across Activity re-creation (such as from a configuration change). If set, the fragment lifecycle will be slightly different when an activity is recreated: `onDestroy()` will not be called (but `onDetach()` still will be, because the fragment is being detached from its current activity). `onCreate(Bundle)` will not be called since the fragment is not being re-created. `onAttach(Activity)` and `onActivityCreated(Bundle)` will still be called.
`Unit`	`setReturnTransition(@Nullable transition: Any?)` Sets the Transition that will be used to move Views out of the scene when the Fragment is preparing to be removed, hidden, or detached because of popping the back stack. The exiting Views will be those that are regular Views or ViewGroups that have `ViewGroup#isTransitionGroup` return true. Typical Transitions will extend `android.transition.Visibility` as entering is governed by changing visibility from `View#VISIBLE` to `View#INVISIBLE`. If `transition` is null, entering Views will remain unaffected. If nothing is set, the default will be to use the same value as set in `setEnterTransition(Object)`.
`Unit`	`setSharedElementEnterTransition(@Nullable transition: Any?)` Sets the Transition that will be used for shared elements transferred into the content Scene. Typical Transitions will affect size and location, such as `android.transition.ChangeBounds`. A null value will cause transferred shared elements to blink to the final position.
`Unit`	`setSharedElementReturnTransition(@Nullable transition: Any?)` Sets the Transition that will be used for shared elements transferred back during a pop of the back stack. This Transition acts in the leaving Fragment. Typical Transitions will affect size and location, such as `android.transition.ChangeBounds`. A null value will cause transferred shared elements to blink to the final position. If no value is set, the default will be to use the same value as `setSharedElementEnterTransition(Object)`.
`Unit`	`setTargetFragment(@Nullable fragment: Fragment?, requestCode: Int)` Optional target for this fragment. This may be used, for example, if this fragment is being started by another, and when done wants to give a result back to the first. The target set here is retained across instances via `FragmentManager.putFragment()`.
`Unit`	`setUserVisibleHint(isVisibleToUser: Boolean)` Set a hint to the system about whether this fragment's UI is currently visible to the user. This hint defaults to true and is persistent across fragment instance state save and restore. An app may set this to false to indicate that the fragment's UI is scrolled out of visibility or is otherwise not directly visible to the user. This may be used by the system to prioritize operations such as fragment lifecycle updates or loader ordering behavior. Note: This method may be called outside of the fragment lifecycle. and thus has no ordering guarantees with regard to fragment lifecycle method calls.
`Boolean`	`shouldShowRequestPermissionRationale(@NonNull permission: String)` Gets whether you should show UI with rationale for requesting a permission. You should do this only if you do not have the permission and the context in which the permission is requested does not clearly communicate to the user what would be the benefit from granting this permission. For example, if you write a camera app, requesting the camera permission would be expected by the user and no rationale for why it is requested is needed. If however, the app needs location for tagging photos then a non-tech savvy user may wonder how location is related to taking photos. In this case you may choose to show UI with rationale of requesting this permission.
`Unit`	`startActivity(intent: Intent!)` Call `Activity#startActivity(Intent)` from the fragment's containing Activity.
`Unit`	`startActivity(intent: Intent!, @Nullable options: Bundle?)` Call `Activity#startActivity(Intent, Bundle)` from the fragment's containing Activity.
`Unit`	`startActivityForResult(intent: Intent!, requestCode: Int)` Call `Activity#startActivityForResult(Intent, int)` from the fragment's containing Activity.
`Unit`	`startActivityForResult(intent: Intent!, requestCode: Int, @Nullable options: Bundle?)` Call `Activity#startActivityForResult(Intent, int, Bundle)` from the fragment's containing Activity.
`Unit`	`startIntentSenderForResult(intent: IntentSender!, requestCode: Int, @Nullable fillInIntent: Intent?, flagsMask: Int, flagsValues: Int, extraFlags: Int, @Nullable options: Bundle?)` Call `Activity#startIntentSenderForResult(IntentSender, int, Intent, int, int, int, * Bundle)` from the fragment's containing Activity.
`Unit`	`startPostponedEnterTransition()` Begin postponed transitions after `postponeEnterTransition()` was called. If postponeEnterTransition() was called, you must call startPostponedEnterTransition() or `FragmentManager#executePendingTransactions()` to complete the FragmentTransaction. If postponement was interrupted with `FragmentManager#executePendingTransactions()`, before `startPostponedEnterTransition()`, animations may not run or may execute improperly.
`String`	`toString()`
`Unit`	`unregisterForContextMenu(@NonNull view: View)` Prevents a context menu to be shown for the given view. This method will remove the `OnCreateContextMenuListener` on the view.

From class PreferenceDialogFragmentCompat

`DialogPreference!`	`getPreference()` Get the preference that requested this dialog. Available after `onCreate(Bundle)` has been called on the `PreferenceFragmentCompat` which launched this dialog.
`Unit`	`onBindDialogView(view: View!)` Binds views in the content view of the dialog to data. Make sure to call through to the superclass implementation.
`Unit`	`onClick(dialog: DialogInterface!, which: Int)`
`Dialog`	`onCreateDialog(savedInstanceState: Bundle?)`
`View!`	`onCreateDialogView(context: Context!)` Creates the content view for the dialog (if a custom content view is required). By default, it inflates the dialog layout resource if it is set.
`Unit`	`onDismiss(@NonNull dialog: DialogInterface)`
