title: Get touch position while dragging
body: <p>I have some views which I like to drag around. The views are within 
  a LinearLayout, which itself is within a scrollview.</p>
  
  <p>I want to get the position of the current finger (touch), to 
  make a smooth scroll on my scrollview, depending of the 
  height of the current drag.</p>
  
  <p>I start my draggin after a long click with the 
  View build-in listener startDrag</p>
  
  <pre><code>view.startDrag(null, shadowBuilder, view, 0);
  </code></pre>
  
  <p>I am also able to get the relativ position of the drag 
  on the view that is currently hovered by </p>
  
  <pre><code>view.setOnDragListener(new OnDragListener() {
          @Override
          public boolean onDrag(View v, DragEvent event) {
              //get event positions
          }
      });
  </code></pre>
  
  <p>But this only works for the view where the drag shadow is currently on 
  and DragEvent only provides relative positions, not raw positions.</p>
  
  <p><strong>What I need is the position of the finger, while the drag happens.</strong> Unfortunately all onTouchEvents get consumed while dragging.</p>
  
  <p>Does anybody know how I get this to work?</p>
  
  <p><em>Ps: One way that works (kind of) which I currently use, is to calculate the 
  position of the touch via the dragEvent.relativePosition in combination
  with the view position. But isn't there a better way to go?</em></p>
