title: Show Bottom Buttons Bar in ListView while scrolling up and hide when scrolling down
body: <p>I have a huge listview, with a Bottom bar with three buttons in them. Now, my question is, Is there a way to hide the bottom bar (With Buttons) while scrolling down, and show them up while scrolling up the listview?</p>
  
  <p>Just like how Google+ Handles in the iOS App. </p>
