Known Direct Subclasses

PlaybackBannerControlGlue<T extends PlayerAdapter>,PlaybackTransportControlGlue<T extends PlayerAdapter>

A base abstract class for managing a PlaybackControlsRow being displayed in PlaybackGlueHost. It supports standard playback control actions play/pause and skip next/previous. This helper class is a glue layer that manages interaction between the leanback UI components PlaybackControlsRow PlaybackRowPresenter and a functional PlayerAdapter which represents the underlying media player.

The app must pass a PlayerAdapter in constructor for a specific implementation e.g. a MediaPlayerAdapter.

The glue has two action bars: primary action bars and secondary action bars. Apps can provide additional actions by overriding onCreatePrimaryActions(ArrayObjectAdapter) and / or onCreateSecondaryActions(ArrayObjectAdapter) and respond to actions by overriding onActionClicked(Action).

The subclass is responsible for implementing the "repeat mode" in onPlayCompleted().
