当点击的时候，会先调用顶级viewgroup的dispatchTouchEvent，如果顶级的viewgroup拦截了此事件（onInterceptTouchEvent返回true），则此事件序列由顶级viewgroup处理。如果顶级viewgroup设置setOnTouchListener，则会回调接口中的onTouch，此时顶级的viewgroup中的onTouchEvent不再回调，如果不设置setOnTouchListener则onTouchEvent会回调。如果顶级viewgroup设置setOnClickListener，则会回调接口中的onClick。如果顶级viewgroup不拦截事件，事件就会向下传递给他的子view，然后子view就会调用它的dispatchTouchEvent方法。 about android-daily-interview CLOSED
