FragmentActivity

Kotlin |Java

open class FragmentActivity : ComponentActivity, ActivityCompat.OnRequestPermissionsResultCallback, RequestPermissionsRequestCodeValidator

androidx.activity.ComponentActivity
↳	androidx.fragment.app.FragmentActivity

Known Direct Subclasses

AppCompatActivity, WatchFaceConfigActivity

AppCompatActivity	Base class for activities that wish to use some of the newer platform features on older Android devices.
WatchFaceConfigActivity	Config activity for the watch face, which supports complication and provider selection, as well as userStyle configuration.

Base class for activities that want to use the support-based Fragments.

Known limitations:

When using the <fragment> tag, this implementation can not use the parent view's ID as the new fragment's ID. You must explicitly specify an ID (or tag) in the <fragment>.

Summary

Public constructors
`<init>()` Default constructor for FragmentActivity.
`<init>(@LayoutRes contentLayoutId: Int)` Alternate constructor that can be used to provide a default layout that will be inflated as part of `super.onCreate(savedInstanceState)`.

open Unit	`onMultiWindowModeChanged(isInMultiWindowMode: Boolean)` Note: If you override this method you must call `super.onMultiWindowModeChanged` to correctly dispatch the event to support fragments attached to this activity.
open Unit	`onPanelClosed(featureId: Int, @NonNull menu: Menu)` Call onOptionsMenuClosed() on fragments.
open Unit	`onPictureInPictureModeChanged(isInPictureInPictureMode: Boolean)` Note: If you override this method you must call `super.onPictureInPictureModeChanged` to correctly dispatch the event to support fragments attached to this activity.
open Boolean	`onPreparePanel(featureId: Int, @Nullable view: View?, @NonNull menu: Menu)` Dispatch onPrepareOptionsMenu() to fragments.
open Unit	`onRequestPermissionsResult(requestCode: Int, @NonNull permissions: Array<String!>, @NonNull grantResults: IntArray)`
open Unit	`onStateNotSaved()` Hook in to note that fragment state is no longer saved.

open Unit	`setExitSharedElementCallback(@Nullable listener: SharedElementCallback?)` When `android.app.ActivityOptions#makeSceneTransitionAnimation(Activity, * android.view.View, String)` was used to start an Activity, listener will be called to handle shared elements on the launching Activity.
