处理拦截触摸事件，并且不延长的ViewGroup [英] Handling Intercept touch event without extending ViewGroup

问题描述

我有一个 RelativeLayout的这个布局有在这近10次。

I have a one RelativeLayout and this layout is having nearly 10 views in it.

我已经设置 OnTouchListener 来此布局，做一些工作，并返回真。

I have set OnTouchListener to this Layout and doing some work in it and returning true.

这监听器工作正常，当我触摸那里有没有查看布局（平均在空白区域）。如果我谈谈这个布局的子视图，该监听器不点火...

this listener is working fine when I touch the layout where there are no View (mean on Empty area). If I touch on child views of this layout, this listener is not firing...

和从文档，我明白了，我们可以覆盖 onInterceptTouchEvent（）通过扩展的ViewGroup（所以这里RelativeLayout的），并处理触摸事件之前，孩子的意见消耗本次活动..

and from the documentation, I understood that we can override onInterceptTouchEvent() by extending ViewGroup (so here RelativeLayout) and handle touch events before child views consume this event...

这会做的伎俩，但我需要修改，​​我用我的CustomRelativeLayout取代RelativeLayout的需要此功能很多的XML文件。

this will do a trick, but I need to modify many xml files where I need this functionality by replacing RelativeLayout with my CustomRelativeLayout.

所以我的问题是：

有没有什么办法来处理触摸事件的 RelativeLayout的（ofcourse的ViewGroup）的 RelativeLayout的子视图之前消耗事件？我不希望延长 RelativeLayout的 ...

is there any way to handle touch event for RelativeLayout (ofcourse ViewGroup) before child views in RelativeLayout consumes event? I don't want to extend RelativeLayout...

推荐答案

尝试重写

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    return super.dispatchTouchEvent(ev);
}

活动的。 此方法是第一个过程的触摸事件。 但在这种情况下，你需要和意见当前坐标工作

of Activity. This method is the first that process touch events. But in this case you need to work with current coordinates of views
