title: Android: ActionBar like the stock browser
body: <p>I want my ActionBar to act like it does in the stock/default Android browser:
  It visible at the top of the page, but as the user scrolls down, the bar scrolls out of view, how ever if you scroll the page upward towards the top, the bar comes in to view again, but will hide after some time out, when it does this, it does not affect the underlying view.</p>
  
  <p>I've tried implementing auto-hiding using timers but when the ActionBar hides, it moves up the scrollable view underneath so it looks as is my whole page shifts up instead of the ActionBar floating over the top of the view.</p>
