示例1: duplicateTouchEventForChildren
import android.view.MotionEvent; //導入方法依賴的package包/類
/**
* Duplicate touch events to child views.
* We want to dispatch a down motion event and the move events to
* child views, but calling dispatchTouchEvent() causes StackOverflowError.
* Therefore we do it manually.
*
* @param ev motion event to be passed to children
* @param pendingEvents pending events like ACTION_DOWN. This will be passed to the children before ev
