PlaybackFragment

public class PlaybackFragment
extends Fragment

java.lang.Object
   ↳ android.app.Fragment
     ↳ androidx.leanback.app.PlaybackFragment

This class is deprecated.
use PlaybackSupportFragment

A fragment for displaying playback controls and related content.

A PlaybackFragment renders the elements of its ObjectAdapter as a set of rows in a vertical list. The Adapter's PresenterSelector must maintain subclasses of RowPresenter.

A playback row is a row rendered by PlaybackRowPresenter. App can call setPlaybackRow(Row) to set playback row for the first element of adapter. App can call setPlaybackRowPresenter(PlaybackRowPresenter) to set presenter for it. setPlaybackRow(Row) and setPlaybackRowPresenter(PlaybackRowPresenter) are optional, app can pass playback row and PlaybackRowPresenter in the adapter using setAdapter(ObjectAdapter).

Auto hide controls upon playing: best practice is calling setControlsOverlayAutoHideEnabled(boolean) upon play/pause. The auto hiding timer will be cancelled upon tickle() triggered by input event.
