ScaleGestureDetector triggers onScaleEvent with single finger touch
<p>I have code that onTouchEvent passes the touch event to a member ScaleGestureDetector and if the scale GD triggers a onScaleEvent on my scale listener, I scale up the display item. If the onScale event is not triggered I treat this event as a potential drag and move the displayed item around. I have observed that on certain devices the ScaleGestureDetector triggers an onScale event for me, even if there is just a single finger touching the screen. Is this expected? What is the recommended mechanism to deal with scales and drags at the same time?</p>
