@MaAnQing 这段是伪代码，主要是为了描述三者之间的关系，并非实际的代码。

@singwhatiwanna 我知道这是伪代码，按照这段伪代码可知当onInterceptTouchEvent(ev)返回为true时才会调用onTouchEvent(ev)，但我在实际开发中，我遇到onInterceptTouchEvent返回false时仍会触发onTouchEvent事件，这样是不是就说明上述为代码有问题，是不是说明三者之间的关系并非为上述为伪代码所描述的那样

onInterceptTouchEvent返回false表示ViewGroup不拦截这个事件,自然会分发到子View,但是如果子View的onTouch/onTouchEvent同样返回false,即子View不处理该事件,事件又会回到上级ViewGroup处理,即你说的调用onTouchEvent.刚看本书,不知理解是否正确

@MaAnQing 你说的那个问题书中有详细说明，我也理解。上面那段伪代码，如果考虑到各种情况，那就不能那么简洁了，就没有意义了，还请分别去理解。

@kutear 应该就是你讲的那样，没有验证
