title: Why motionEvent.getX() return inconsistent values, when using setScaleX()?
body: <p>I've child view resides in a ViewGroup.
  I'd like to scale (zoom) the child with a pinch.
  I'm using setScaleX/Y() to scale the child. The scale is calculated form distance between 2 pointers, in OnTouch().
  But when I set the scale of the child it makes motionEvent.getX() inconsistent, which makes the scale to be inconsistent:</p>
  
  <pre><code>case MotionEvent.ACTION_MOVE:
      p1.set(ev.getX(firstPointerIndex), v.getY(firstPointerIndex));
      Log.d(TAG,"Touch xy: " + ev.getX(firstPointerIndex) + "," +  ev.getY(firstPointerIndex));
      this.setScaleX(scale);
      this.setScaleY(scale);
      break;
  </code></pre>
  
  <h2>Output</h2>
  
  <p>This is the output of one pointer:</p>

  <h2>Question</h2>
  
  <p>The problem is the jumps 35-54 at x-coord or 135-191 at y-coord. I can't understand where these jumps are coming from.
  When I don't use setScaleX/Y(), the ev.getX/T() are consistent - no jumps. Could anyone light me? Shouldn't I use these scale methods? Does they affect the ev.getX/Y()? How can I implement the zoom(with pinch) of the view in other way? </p>
