title: How to add Page Dots for 2D Pickers in Android Wear?
body: <p>Several stock apps use this kind of "page dots" to guide the user. When I implemented 2D picker, I found out page dots are not part of it. I tried to use images to simulate the effect, but my <code>ImageView</code> moves with the page when user swipes from page to page. </p>
  
  <p>How can I implement this kind of "page dots" that do not move when user swipes? Furthermore, can I control whether/when these dots would appear and fade?</p>
