The best way to work around this scenario is to use a <code>ViewGroup</code> and implement the <code>onInterceptTouchEvent</code> method to manually route the touch events as you see fit.

The easiest way I found to force single touch across an entire app is to set it using a theme:

<pre><code>&lt;style name="MyTheme" parent="@android:style/Theme.Holo.Light"&gt;
 &lt;item name="android:windowEnableSplitTouch"&gt;false&lt;/item&gt;
 &lt;item name="android:splitMotionEvents"&gt;false&lt;/item&gt;
&lt;/style&gt;
</code></pre>

Manifest:

<pre><code> &lt;application
 android:label="@string/app_name"
 android:theme="@style/MyTheme" &gt;
</code></pre>

I think you can override onTouchEvent for any view.

Override dispatchTouchEvent and intercept all touches there, for all multi touches the pointercount is more than one.

<pre><code> if(ev.getPointerCount() &gt; 1)
 {
 Log.d("Multitouch detected!");
 ev.setAction(MotionEvent.ACTION_CANCEL);
 }
</code></pre>

This cancels the touches and clears the pressed state of the buttons without taking any further action.

my style for example

 &lt;item name=&quot;android:splitMotionEvents&quot;&gt;false&lt;/item&gt;
&lt;/style&gt;

&lt;style name=&quot;AppTheme.NoActionBar&quot;&gt;
 &lt;item name=&quot;windowActionBar&quot;&gt;false&lt;/item&gt;
 &lt;item name=&quot;windowNoTitle&quot;&gt;true&lt;/item&gt;

Here horizentalLinearGridItem is parentLayout view where we insert child views.
In my code its LinearLayout. In this LinearLayout I added child views. But when I clicked two child views simultaneously, both were getting the events. To block that I used the above code.

I got it to work for me by just adding some code in <code>OnTouchEvent</code> method,

<pre><code>boolean action_down_required = false;

@Override
public boolean onTouchEvent(MotionEvent event) {

 int action = event.getAction();

 if(event.getPointerCount() &gt; 1){
 action_down_required = true;
 return true;
 }

 if(action_down_required){
 action = MotionEvent.ACTION_DOWN;
 }

 switch (action) {
 case MotionEvent.ACTION_DOWN:

 // your code goes here...

 action_down_required = false;
 break;

 // Other events...
</code></pre>

I have several Views on an Activity which a user wants to touch quickly in succession and I capture these touches using a <code>TouchListener</code> and handling <code>MotionEvent.ACTION_DOWN</code>. However, if the user is using two hands, it's very likely that the next View will be 'Touch'ed before the user pulls the previous finger up. In this scenario, a <code>MotionEvent.ACTION_MOVE</code> is fired for the first view rather than the desired <code>MotionEvent.ACTION_DOWN</code> for the second view.

Is there any way to work around or prevent this behavior? I've tried dispatching a new event with <code>MotionEvent.ACTION_UP</code> and also removing the event listener but neither seem to work.

我在用户想要快速触摸的活动上有几个视图，并且我使用TouchListener和处理MotionEvent.ACTION_DOWN来捕捉这些触摸。但是，如果用户使用两只手，则很可能在用户提起上一个手指之前，下一个视图将被“触摸”。在这种情况下，将为第一个视图触发MotionEvent.ACTION_MOVE，而不是为第二个视图触发所需的MotionEvent.ACTION_DOWN。有什么方法可以解
