title: How to use setDisplayOptions method for action bar?
body: <p>I want for an action bar to set:</p>
  
  <pre><code> actionBar.setDisplayShowTitleEnabled(true);
   actionBar.setDisplayHomeAsUpEnabled(true);
  </code></pre>
  
  <p>and in other place:</p>
  
  <pre><code>  actionBar.setDisplayShowTitleEnabled(true);
    actionBar.setDisplayHomeAsUpEnabled(false);
  </code></pre>
  
  <p>but using instead the <code>setDisplayOptions</code> method (which seems that is recommended when you want "to set several display options at once") but do not know how to use it ...</p>
