title: How to make the Toolbar snap into view or out of view when using Google Design Library?
body: <p>I am trying to achieve an effect like WhatsApp has, where the Toolbar (when scrolled) will clip into view magnetlike, or out of view magnetlike.</p>
  
  <p>What I have im my MainActivity XML:</p>
  
  <ul>
  <li>DrawerLayout - Base Layout</li>
  <li>CoordinatorLayout - Layout for the Appbar and Toolbar and Tabs</li>
  <li>AppBarLayout - For holding Toolbar and Tabs</li>
  <li>Toolbar - has THIS flag:               <code>app:layout_scrollFlags="scroll|enterAlways"</code></li>
  <li>SlidingTabLayout - Displays tabs</li>
  <li>ViewPager - For tabs</li>
  <li>RecyclerView - For coordinatorlayout</li>
  </ul>
  
  <p>Now dont get me wrong, it works, when I scroll down the toolbar gets pushed out of view but say I stop scrolling halfway, then the toolbar just sits there half hidden out of view and the other half in view..</p>
  
  <p>How can I approach solving this problem, as I want it to either snap out of view or into view.</p>
