刚看了下，确实有你说的这个问题。在那里return false就可以了。我之前也没注意，很感谢你的提出。

这是为什么啊？？
我查了一下在onTouchEvent中，返回true表示消费了这次事件，返回false表示未消费。
按理不是应该消费了就不再次执行了吗？
我抓了下日志，是if那句判断执行了四次，有时候是五次，好不可思议啊

这是事件消费与传递的知识点，如果不清楚可以再回去看看。返回false就是本次的事件序列，后面的MOVE和UP都不由这个View处理了，然而返回true就是代表这个View会消费掉整个的事件序列后面的MOVE和UP都会由这个View来处理，你知道的只要你的手指没离开这个View MOVE会一直执行。这也就是会出现多次的原因。
