  <p>Does anyone know where can I find a tutorial or example on how to achive this kind of number picker dialog on android? I googled everything but only managed to find examples where you have to create your own buttons with custom images etc. Can this be done in simple way?</p>
  
  <p>All I could find was this: <a href="http://www.quietlycoding.com/?p=5" rel="noreferrer">http://www.quietlycoding.com/?p=5</a>
  but it doesn't quite help me.</p>
