你改了DragLayout的touch拦截吧？

[xmuSistone]

DragLayout里面的dispatchTouchEvent最好不要改动了。DragLayout上游ParentView的touch传递策略可能有误，理论上来说，shouldInterceptTouchEvent是不会报异常的。

@xmuSistone 没有改,代码原封不动的加上去的，部分手机出现了这个bug

[xmuSistone]

什么型号的手机呢？

[EmilyCYY]

您好，我也出现了这个问题。是在魅族note2上出现的，复现：我把scrollview改了之后放在第二个fragment中，然后在scrollview中进行放大的手势就会出现这个问题了。draglayout我是没有改动过的

@EmilyCYY 你更新下DragLayout，提了新代码

[EmilyCYY]

@xmuSistone 非常感谢！
