title: Strike through text setting in action bar tab dynamicaly
body: <p>I want to set text in action bar tab dynamically. Showing that the feature is not available.  How to do that? i had changed the disable tab icon dynamically as you can see in the image in the <a href="https://drive.google.com/file/d/0B_8n82ljiOxIcUZOeHJsdVRZUzQ/view?usp=sharing" rel="nofollow">link</a></p>
  
  <pre><code>audioTab = actionBar.newTab();
  actionBar.setIcon(mSectionsPagerAdapter.getIcon(i));
  actionBar.setText(mSectionsPagerAdapter.getPageTitle(i));
  actionBar.setTabListener(this);
  actionBar.addTab(audioTab);
  //changing icon dynamically
  audioTab.setIcon(R.drawable.audio_disabled);
  videoTab.setIcon(R.drawable.video_disabled);
  </code></pre>
