触摸听众的亲子观 [英] Touch Listeners for Parent and Child Views

问题描述

我有一个 Horizo​​ntalScrollView 在 ViewPager ，我已经禁用的观点寻呼机的ontouchevent，但问题是水平滚动视图受此干扰。它不能正常工作，仅移动了一点。

I have a HorizontalScrollView inside a ViewPager , I have disabled the ontouchevent of the view pager, but the problem is horizontal scroll view is disturbed by this. It doesn't work properly, only moves a little.

我只是想了解触摸监听功能， onInterceptTouchEvent 和的TouchEvent 的父母和孩子的看法，有什么是为了他们的呼召，如果我在子视图触摸？

I just want to understand the touch listeners functionality , onInterceptTouchEvent and touchEvent of the parent and child view, what is the order their calling if i touch on a child view?

推荐答案

的TouchEvent首先由儿童观来处理，如果不处理它，这意味着返回false，父视图将会处理它。但onIterceptTouchEvent是之前的TouchEvent

touchEvent is first be handled by child View , if it doesn't handle it ,which means return false,the parent view will handle it. But onIterceptTouchEvent is before touchEvent.
