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().
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();
}
}
