title: Circular scale animation
body: <p>I'm trying to achieve an animation which scales over a view like this:</p>
  
  <p><a href="https://i.stack.imgur.com/6d1tr.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6d1tr.jpg" alt="Curved animation"></a></p>
  
  <p>At the moment I'm using a scale animation loaded from xml:</p>
  
  <p></p>
  
  <p>This in action looks like this: </p>
  
  <p><a href="https://i.stack.imgur.com/mwoPH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mwoPH.png" alt="Square like scale animation"></a></p>
  
  <p>It scales more like a square.</p>
  
  <p>I was using ObjectAnimator/ValueAnimator with properties before.</p>
  
  <p>Some devices had specific problems with measuring heights for scaling so I reverted to using xml definitions.</p>
  
  <p>Does anyone have any clue how to achieve the above?</p>
