This class represents the UI (e.g. Fragment/Activity) hosting playback controls and defines the interaction between PlaybackGlue and the host. PlaybackGlueHost provides the following functions:

  • Render UI of PlaybackGlue: setPlaybackRow(Row), setPlaybackRowPresenter(PlaybackRowPresenter).
  • Client for fragment/activity onStart/onStop: setHostCallback(HostCallback).
  • Auto fade out controls after a short period: setFadingEnabled(boolean).
  • Key listener and ActionListener. setOnKeyInterceptListener(View.OnKeyListener), setOnActionClickedListener(OnActionClickedListener).
    • Subclass of PlaybackGlueHost may implement optional interfaces:
  • SurfaceHolderGlueHost to provide SurfaceView for video playback.
  • PlaybackSeekUi to provide seek UI to glue
    • These optional interfaces should be accessed by glue in onAttachedToHost(PlaybackGlueHost).
