Android:在childview的onLongclick上调用parentview的onTouch事件

所以我在相对布局中有两个叠加视图。要求是在长按第一个视图后调用第二个视图的触摸事件(以应用手势)。 真的搞砸了触摸和点击事件。如果有人能提供更好的解决方案。

这是我的代码:

gestureDetector = new GestureDetector(this, new MyGestureDetector());
gestureListener = new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        MainActivity.this.event= event;
        return gestureDetector.onTouchEvent(event);
    }
};
gestureDetector.setIsLongpressEnabled(false);
above = (Button) findViewById(R.id.above);
above.setOnTouchListener(gestureListener);

below = (Button) findViewById(R.id.below);
below.setOnLongClickListener(new OnLongClickListener() {    
    @Override
    public boolean onLongClick(View v) {
        Log.d("long", "click");
        //call on down of above here and set visibility gone of below
        return true;
    }
});

我也尝试过dispatchtouchevent(事件);但是哪个事件必须从这里发出?

MyGestureDetector类是:

class MyGestureDetector extends SimpleOnGestureListener {

        @Override
    public boolean onDown(MotionEvent e) {
            Log.e("action", "down");
             //for applying scroll gestures onto it
            return true;
    }

}
