title: ActionBar calendar spinner
body: <p>In the <a href="http://developer.android.com/intl/ru/design/building-blocks/spinners.html" rel="nofollow noreferrer">android design guidance</a> there is an image of "ActionBar calendar spinner":</p>
  
  <p><img src="https://i.stack.imgur.com/t0aBI.png" alt="enter image description here"></p>
  
  <p>Is there a code realization for this widget (if exists)? Is it a native SDK widget or just design pattern?</p>
