经过这里好心人的大力帮助，我终于几乎可以使用 GestureOverlayView 启动并运行我的小游戏面板（即表面视图类）。通过使用 addView 我终于能够添加 GestureOverlayView 并让它工作，问题是调用这个：

    /** create the login form */
private ViewGroup _createGameStuffs() {
  GestureOverlayView gestures = new GestureOverlayView(this);       
  gestures.setOrientation(gestures.ORIENTATION_VERTICAL);
  gestures.setEventsInterceptionEnabled(true);
  gestures.setGestureStrokeType(gestures.GESTURE_STROKE_TYPE_MULTIPLE);

  gestures.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
          LayoutParams.FILL_PARENT));

  //GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
  gestures.addOnGesturePerformedListener(this);
  Panel p = new Panel(this); //my game view
  panel.addView(p,0);       //add it to the group
  panel.addView(gestures,1); //add the gestureoverlayview i made to the group

  return panel;
}

    public void onCreate(Bundle savedInstanceState) {
               super.onCreate(savedInstanceState);
               requestWindowFeature(Window.FEATURE_NO_TITLE);
               mLibrary = GestureLibraries.fromRawResource(this, R.raw.myspells);

                 // create the panel to enclose everything
               View mainPanel = _createGameStuffs();

              // show the panel on the screen
              setContentView(mainPanel);
              //setContentView(p);
 }

根据我给出的索引，哪个视图占主导地位。这让我相信我的游戏面板必须作为子视图添加到 GestureOverlayView，这是正确的吗？如果是这样，我如何获得 GestureOverlayView 的子视图？还是反过来， GestureOverlayView 成为我主视图的子视图？
