Use MotionEvent.getPointerCount(). You can read more details here: Respond to touch events

public boolean onTouchEvent(MotionEvent event) {
    int action = event.getAction();
    switch (action & MotionEvent.ACTION_MASK) {
        case MotionEvent.ACTION_POINTER_DOWN:
            int count = event.getPointerCount();
            // TODO: Do something you want here
            break;
    }
}
