Try add onTouchListener to RelativeLayout

<pre><code>RelativeLayout rl = (RelativeLayout) findViewById( R.id.relativeLauout );
 rl.setOnTouchListener( new OnTouchListener() {

 @Override
 public boolean onTouch(View v, MotionEvent event) {
 // do something
 return false;
 }
 });
</code></pre>

or use method onTouchEvent from Activity

<pre><code>@Override
public boolean onTouchEvent(MotionEvent event) {
 // TODO Auto-generated method stub
 return super.onTouchEvent(event);
}
</code></pre>

}|code-block|syntax|javascript|1947473|Activity的。这个方法是第一个处理触摸事件的方法。但在这种情况下，您需要使用视图的当前坐标|offset|length|style|CODE|1947474|entityMap^0|0|0|0|8|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Try to override

<pre><code>@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
 return super.dispatchTouchEvent(ev);
}
</code></pre>

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

blocks|key|2651863|text|您可以简单地在xml中设置：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2651864|android:clickable="true"|code-block|syntax|javascript|2651865|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can simply set in your xml:

<pre><code>android:clickable="true"
</code></pre>

blocks|key|36125|text|在处理ACTION_DOWN事件时，尝试在子视图的onTouchEvent()方法中返回false。因此，转发的触摸事件不会被发送给子视图，也就是事件不会被消费。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|36126|entityMap^0|3|B|P|E|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Try to return false in the <code>onTouchEvent()</code> method of child views when processing <code>ACTION_DOWN</code> event. So the forwarding touch events will not be sent to child views, aka event not consumed.

blocks|key|4765389|text|虽然不一定是理想的，但这对于没有动态内容的较小布局很有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4765390|在xml中，将android:clickable="false"设置为布局中ViewGroup的所有后代(包括嵌套的ViewGroups及其子项)。每个被点击的子节点都会将点击传递给它的父节点，最终到达ViewGroup的默认触摸处理程序。确保将根ViewGroup设置为android:clickable="true"或viewgroup.setClickable(true)，您希望在该根目录中获取单击事件|offset|length|style|CODE|4765391|如果动态添加视图，请确保在将其添加到视图层次结构之前调用view.setClickable(false);。|4765392|entityMap^0|0|7|P|3S|O|4H|S|0|S|P|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]|$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@$D|U|E|V|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|K|$]]

While not necessarily being ideal, this works well for smaller layouts that won't have dynamic content.

In xml, set <code>android:clickable="false"</code> to all descendants of the ViewGroup in the layout (including nested ViewGroups and their children). Each child that gets clicked on will then propagate the click to its parent, eventually getting to the ViewGroup's default touch handlers. Make sure to set root ViewGroup, where you want to get the click events as <code>android:clickable="true"</code> or <code>viewgroup.setClickable(true)</code>

If you add views dynamically, make sure to call <code>view.setClickable(false);</code> before adding it to the view hierarchy.

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

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

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...

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

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

so my question is:

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

我有一个RelativeLayout，这个布局有将近10个视图。我已经将OnTouchListener设置为这种布局，并在其中做了一些工作并返回true。当我触摸没有视图的布局(在空白区域)时，这个侦听器工作得很好。如果我接触到此布局的子视图，则此侦听器不会触发...从文档中我了解到，我们可以通过扩展ViewGroup...
