Inherited methods

From androidx.leanback.widget.OnActionClickedListener

abstract void

onActionClicked(@NonNull Action action)

Callback fired when the host fragment receives an action.

From androidx.leanback.media.PlaybackControlGlue

`void`	`enableProgressUpdating(boolean enable)` Override this to start/stop a runnable to call `updateProgress` at an interval such as `getUpdatePeriod`.
`PlaybackControlsRow`	`getControlsRow()` Returns the playback controls row managed by the glue layer.

`int[]`	`getFastForwardSpeeds()` Returns the fast forward speeds.
`PlaybackRowPresenter`	`getPlaybackRowPresenter()` Returns the playback row Presenter to be passed to `PlaybackGlueHost` in `onAttachedToHost`.
`int[]`	`getRewindSpeeds()` Returns the rewind speeds.
`int`	`getUpdatePeriod()` Returns the time period in milliseconds that should be used to update the progress.
`boolean`	`isFadingEnabled()` Returns true if controls are set to fade when media is playing.
`boolean`	`isPlaying()` Returns true if media is currently playing.
`void`	`onActionClicked(Action action)` Handles action clicks.
`void`	`onAttachedToHost(@NonNull PlaybackGlueHost host)` This method is called attached to associated `PlaybackGlueHost`.
`void`	`onCreateControlsRowAndPresenter()` Instantiating a `PlaybackControlsRow` and corresponding `PlaybackControlsRowPresenter`.
`void`	`onCreatePrimaryActions(SparseArrayObjectAdapter primaryActionsAdapter)` May be overridden to add primary actions to the adapter.
`void`	`onCreateSecondaryActions(ArrayObjectAdapter secondaryActionsAdapter)` May be overridden to add secondary actions to the adapter.
`void`	`onDetachedFromHost()` This method is called when current associated `PlaybackGlueHost` is attached to a different `PlaybackGlue` or `PlaybackGlueHost` is destroyed .
`void`	`onHostStart()` This method is called when `PlaybackGlueHost` is started.
`void`	`onHostStop()` This method is called when `PlaybackGlueHost` is stopped.
`boolean`	`onKey(View v, int keyCode, KeyEvent event)` Handles key events and returns true if handled.
`void`	`onMetadataChanged()` Must be called appropriately by a subclass when the metadata state has changed.
`void`	`onStateChanged()` Must be called appropriately by a subclass when the playback state has changed.
