title: React Native overlapping views with elevation not work
body: <p><a href="https://i.stack.imgur.com/b1okI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/b1okI.png" alt="Card elevation with overlapping button"></a></p>
  
  <p>I want to show button above card with elevation, but my problem is button goes behind card. If I remove elevation of card then button shows above card. I want both button above card and card with elevation. How can I achieve this?</p>
  
  <p>Currently I put button below card and give minus marginTop to button, It's working without card elevation but not with elevation. </p>
  
  <p>Note: I tried absolute position and zIndex both but not worked.</p>
