Android LinearLayout Multi-Touch

I am using LinearLayout's to represent different parts of my UI. The idea is that these layouts will be in a grid arrangement. In addition, the user will be able to drag the windows around to re-arrange them. I started by creating my layouts, and everything works great. Then I applied an OnTouchListener to my views:

 touchListener = new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                Log.e("VARS","MotionEvent!");
                if(event.getPointerCount() == 2) {
                Log.e("VARS","It's two!");

                }
                return false;
            }
        };

It completely ignores the case where event.getPointerCount() is two! It seems that this method is only invoked when the pointer count is one. I put this in my manifest:

<uses-feature android:name="android.hardware.touchscreen.multitouch"/>

and it still doesn't work. Does LinearLayout have a special case where only MotionEvent's with a pointer count of one are recognized, or is there something else I'm missing?

You need to change return false to return true. By consuming the MotionEvent, it will work correctly.

You cannot set it higher than 1. It doesnt have something to do with linearlayout.
