我想做的是，当我单触tvtop时，我想将触摸事件传递给tvbottom，tvbottom显示toast。
此外，tvtop与其他触摸事件保持在顶部。
当我刷tvtop时，它不能将touch事件传递给tvbottom。
只有单触必须将触摸事件传递给tvbooth。
如果我返回假tvboottom得到传递的touch事件，但是使用gesturedector它不工作。

tvTop.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
   Toast.makeText(getApplicationContext(),"i am top",Toast.LENGTH_SHORT).show();
    return false;
}
});

我怎么能这么做！
