title: Android Gallery Scale Center Image & Spacing Issue
body: <p>I have an <code>Activity</code> containing a <code>Gallery</code> view.  I've defined an <code>onItemSelectedListener</code> on the <code>Gallery</code>, so that whenever an item is selected I apply a scale animation to the currently selected view.  The listener, and scaling works pretty much as expected, except for one issue. </p>
  
  <p>When I defined the Gallery, I set the <code>spacing</code> attribute, however, after the view is scaled, the spacing is not being set properly.  See the image below as an example of the issue.</p>
  
  <p>Any thoughts on how I can maintain the proper spacing?   </p>
