Programatically add Done button to Android MediaController subclass
===

I want to add a Done button to a MediaController subclass. Here's what I've tried so far:

        private class MediaControllerWithDoneButton extends MediaController {
    		
    		public MediaControllerWithDoneButton(android.content.Context context) {
    			super(context);
    			
    			Button doneButton = new Button(this);
    		}
    	}

I'm getting an error because there isn't a `Button` constructor that takes a `MediaController` instance as a parameter. Since I'm new to Android and Java I could use some help on how to proceed.
