A helper 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 PlaybackControlsRowPresenter and a functional PlayerAdapter which represents the underlying media player.

Apps must pass a PlayerAdapter in the 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().

Sample Code:

 public class MyVideoFragment extends VideoFragment {
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         PlaybackBannerControlGlue playerGlue =
                 new PlaybackBannerControlGlue(getActivity(),
                         new MediaPlayerAdapter(getActivity()));
         playerGlue.setHost(new VideoFragmentGlueHost(this));
         playerGlue.setSubtitle("Leanback artist");
         playerGlue.setTitle("Leanback team at work");
         String uriPath = "android.resource://com.example.android.leanback/raw/video";
         playerGlue.getPlayerAdapter().setDataSource(Uri.parse(uriPath));
         playerGlue.playWhenPrepared();
     }
 }
