| 43 | /** |
| 44 | * A view containing controls for a MediaPlayer. Typically contains the |
| 45 | * buttons like "Play/Pause", "Rewind", "Fast Forward" and a progress |
| 46 | * slider. It takes care of synchronizing the controls with the state |
| 47 | * of the MediaPlayer. |
| 48 | * <p> |
| 49 | * The way to use this class is to instantiate it programatically. |
| 50 | * The MediaController will create a default set of controls |
| 51 | * and put them in a window floating above your application. Specifically, |
| 52 | * the controls will float above the view specified with setAnchorView(). |
| 53 | * The window will disappear if left idle for three seconds and reappear |
| 54 | * when the user touches the anchor view. |
| 55 | * <p> |
| 56 | * Functions like show() and hide() have no effect when MediaController |
| 57 | * is created in an xml layout. |
| 58 | * |
| 59 | * MediaController will hide and |
| 60 | * show the buttons according to these rules: |
| 61 | * <ul> |
| 62 | * <li> The "previous" and "next" buttons are hidden until setPrevNextListeners() |
| 63 | * has been called |
| 64 | * <li> The "previous" and "next" buttons are visible but disabled if |
| 65 | * setPrevNextListeners() was called with null listeners |
| 66 | * <li> The "rewind" and "fastforward" buttons are shown unless requested |
| 67 | * otherwise by using the MediaController(Context, boolean) constructor |
| 68 | * with the boolean set to false |
| 69 | * </ul> |
