title: Show Hide Sherlock Action Bar
body: <p>I have added Sherlock action bar to an activity by using the following line in manifest:</p>
  
  <pre><code>android:theme="@style/Theme.Sherlock.Light"
  </code></pre>
  
  <p>I want to save on screen space and hide the action bar by default and show it only when user taps on the screen. I have seen it in Aldiko app but don't know how to implement it.</p>
  
  <p>Any help is welcomed.</p>
