Disable or prevent multitouch in Activity

Question

I have several Views on an Activity which a user wants to touch quickly in succession and I capture these touches using a TouchListener and handling Motio

Answer 1

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

 if(ev.getPointerCount() > 1)
  {
     Log.d("Multitouch detected!");
     ev.setAction(MotionEvent.ACTION_CANCEL);
  }

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

Answer 2

For me it worked like this. I just put this line in all active styles in my app

<item name="android:splitMotionEvents">false</item>

my style for example

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
      <item name="android:splitMotionEvents">false</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
      <item name="android:splitMotionEvents">false</item>
</style>

Answer 3

I did it like this :

@Override
public boolean onTouchEvent(MotionEvent event) {
    // TODO Auto-generated method stub

    if(event.getPointerCount() > 1) {
        System.out.println("Multitouch detected!");
        return true;
    }
    else
        return super.onTouchEvent(event);
}

I think you can override onTouchEvent for any view.
