SearchSupportFragment

Kotlin |Java

open class SearchSupportFragment : Fragment

kotlin.Any
↳	androidx.fragment.app.Fragment
	↳	androidx.leanback.app.SearchSupportFragment

A fragment to handle searches. An application will supply an implementation of the SearchResultProvider interface to handle the search and return an ObjectAdapter containing the results. The results are rendered into a RowsSupportFragment, in the same way that they are in a .

A SpeechRecognizer object will be created for which your application will need to declare android.permission.RECORD_AUDIO in AndroidManifest file. If app's target version is >= 23 and the device version is >= 23, a permission dialog will show first time using speech recognition. 0 will be used as requestCode in requestPermissions() call. setSpeechRecognitionCallback(SpeechRecognitionCallback) is deprecated.

Speech recognition is automatically started when fragment is created, but not when fragment is restored from an instance state. Activity may manually call startRecognition(), typically in onNewIntent().

Inherited functions

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 context: Context)` Called when a fragment is first attached to its context. `onCreate(Bundle)` will be called after this.
