Kotlin |Java

public abstract class FragmentManager.FragmentLifecycleCallbacks

Callback interface for listening to fragment state changes that happen within a given FragmentManager.

Summary

Public constructors
`FragmentLifecycleCallbacks()`

Public methods
`void`	`onFragmentActivityCreated( @NonNull FragmentManager fm, @NonNull Fragment f, @Nullable Bundle savedInstanceState )` This method is deprecated. To get a callback specifically when a Fragment activity's `onCreate` is called, register a `androidx.lifecycle.LifecycleObserver` on the Activity's `Lifecycle` in `onFragmentAttached`, removing it when it receives the `CREATED` callback.
`void`	`onFragmentAttached( @NonNull FragmentManager fm, @NonNull Fragment f, @NonNull Context context )` Called after the fragment has been attached to its host.
`void`	`onFragmentCreated( @NonNull FragmentManager fm, @NonNull Fragment f, @Nullable Bundle savedInstanceState )` Called after the fragment has returned from the FragmentManager's call to `onCreate`.
`void`	`onFragmentDestroyed(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onDestroy`.
`void`	`onFragmentDetached(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onDetach`.
`void`	`onFragmentPaused(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onPause`.
`void`	`onFragmentPreAttached( @NonNull FragmentManager fm, @NonNull Fragment f, @NonNull Context context )` Called right before the fragment's `onAttach` method is called.
`void`	`onFragmentPreCreated( @NonNull FragmentManager fm, @NonNull Fragment f, @Nullable Bundle savedInstanceState )` Called right before the fragment's `onCreate` method is called.
`void`	`onFragmentResumed(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onResume`.
`void`	`onFragmentSaveInstanceState( @NonNull FragmentManager fm, @NonNull Fragment f, @NonNull Bundle outState )` Called after the fragment has returned from the FragmentManager's call to `onSaveInstanceState`.
`void`	`onFragmentStarted(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onStart`.
`void`	`onFragmentStopped(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onStop`.
`void`	`onFragmentViewCreated( @NonNull FragmentManager fm, @NonNull Fragment f, @NonNull View v, @Nullable Bundle savedInstanceState )` Called after the fragment has returned a non-null view from the FragmentManager's request to `onCreateView`.
`void`	`onFragmentViewDestroyed(@NonNull FragmentManager fm, @NonNull Fragment f)` Called after the fragment has returned from the FragmentManager's call to `onDestroyView`.

Public methods

onFragmentActivityCreated

Added in 1.1.0

Deprecated in 1.3.0

public void onFragmentActivityCreated(
    @NonNull FragmentManager fm,
    @NonNull Fragment f,
    @Nullable Bundle savedInstanceState
)

Called after the fragment has returned from the FragmentManager's call to onActivityCreated. This will only happen once for any given fragment instance, though the fragment may be attached and detached multiple times.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state
`@Nullable Bundle savedInstanceState`	Saved instance bundle from a previous instance

onFragmentAttached

Added in 1.1.0

public void onFragmentAttached(
    @NonNull FragmentManager fm,
    @NonNull Fragment f,
    @NonNull Context context
)

Called after the fragment has been attached to its host. Its host will have had onAttachFragment called before this call happens.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state
`@NonNull Context context`	Context that the Fragment was attached to

onFragmentCreated

Added in 1.1.0

public void onFragmentCreated(
    @NonNull FragmentManager fm,
    @NonNull Fragment f,
    @Nullable Bundle savedInstanceState
)

Called after the fragment has returned from the FragmentManager's call to onCreate. This will only happen once for any given fragment instance, though the fragment may be attached and detached multiple times.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state
`@Nullable Bundle savedInstanceState`	Saved instance bundle from a previous instance

onFragmentDestroyed

Added in 1.1.0

public void onFragmentDestroyed(@NonNull FragmentManager fm, @NonNull Fragment f)

Called after the fragment has returned from the FragmentManager's call to onDestroy.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state

onFragmentDetached

Added in 1.1.0

public void onFragmentDetached(@NonNull FragmentManager fm, @NonNull Fragment f)

Called after the fragment has returned from the FragmentManager's call to onDetach.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state

onFragmentPaused

Added in 1.1.0

public void onFragmentPaused(@NonNull FragmentManager fm, @NonNull Fragment f)

Called after the fragment has returned from the FragmentManager's call to onPause.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state

onFragmentPreAttached

Added in 1.1.0

public void onFragmentPreAttached(
    @NonNull FragmentManager fm,
    @NonNull Fragment f,
    @NonNull Context context
)

Called right before the fragment's onAttach method is called. This is a good time to inject any required dependencies or perform other configuration for the fragment before any of the fragment's lifecycle methods are invoked.

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
`@NonNull Fragment f`	Fragment changing state
`@NonNull Context context`	Context that the Fragment is being attached to

Parameters
`@NonNull FragmentManager fm`	Host FragmentManager
