| /** |
| * A View that contains the controls for MediaPlayer2. |
| * It provides a wide range of UI including buttons such as "Play/Pause", "Rewind", "Fast Forward", |
| * "Subtitle", "Full Screen", and it is also possible to add multiple custom buttons. |
| * |
| * <p> |
| * <em> MediaControlView2 can be initialized in two different ways: </em> |
| * 1) When VideoView2 is initialized, it automatically initializes a MediaControlView2 instance and |
| * adds it to the view. |
| * 2) Initialize MediaControlView2 programmatically and add it to a ViewGroup instance. |
| * |
| * In the first option, VideoView2 automatically connects MediaControlView2 to MediaController, |
| * which is necessary to communicate with MediaSession2. In the second option, however, the |
| * developer needs to manually retrieve a MediaController instance and set it to MediaControlView2 |
| * by calling setController(MediaController controller). |
| * |
| * <p> |
| * There is no separate method that handles the show/hide behavior for MediaControlView2. Instead, |
| * one can directly change the visibility of this view by calling View.setVisibility(int). The |
| * values supported are View.VISIBLE and View.GONE. |
| * In addition, the following customization is supported: |
| * Set focus to the play/pause button by calling requestPlayButtonFocus(). |
| * |
| * <p> |
| * It is also possible to add custom buttons with custom icons and actions inside MediaControlView2. |
| * Those buttons will be shown when the overflow button is clicked. |
| * See {@link VideoView2#setCustomActions} for more details on how to add. |
| * |
| * TODO PUBLIC API |
