推荐答案

尝试覆盖MediaController.

Try overriding MediaController.dispatchTouchEvent()

它更适合您的任务，请在我的回答此处详细了解原因.

It suits your task better, see my answer here for a detailed explanation why.

代码将如下所示:

public class MyMediaController extends MediaController {
    ...
    private WeakReference<Button> mButton;

    // TODO You'll have to call this whenever the layout might have been rebuilt
    // i.e. in onCreate() of your activity (or in onConfigurationChanged() if you
    // handle configuration changes yourself)
    public void setButton(Button button) {
        mButton = new WeakReference<Button>(button);
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent event) {
        int iX = (int) event.getX();
        int iY = (int) event.getY();

        Button button = mButton.get();
        if (button != null) {
            Rect buttonHitRect = new Rect();
            button.getHitRect(buttonHitRect);
            if (buttonHitRect != null && buttonHitRect.contains(iX, iY)) {
                // user hit the button, dispatch event to the button
                button.dispatchTouchEvent(event);
                return true;
            }
        }
        // button did not get hit, pass the touch through
        return super.dispatchTouchEvent(event)
    }
}

尝试一下，让我知道如何进行.

Try this, let me know how it goes.
