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