title: How to hide and show the Android ActionBar like in Google Inbox app?
body: <p>I wnat to show and hide the Android ActionBar when the user scrolls the screen. I found some examples, like <a href="https://stackoverflow.com/questions/25500353/android-actionbar-hide-show-when-scrolling-list-view">this</a> question in SO. But the code showed in this question and its answer makes the action hides after the list have scrolled some pixels, and I want to make this scroll like the Inbox App by Google, that is the action bar is pulled by the Layout according to the user scroll the screen up or down, in other words, I want to show/hide the action bar at the same time the user scroll down/up.</p>
  
  <p>Someone face a problema like this? Some idea?</p>
