title: set title bar name of a activity
body: <p>I'm trying to change my applications activity menu bar title. I managed to change font as follows. Anyone help me to change the name of the title. It may be just a one line, but I can't figure it out. </p>
  
  <pre><code>int actionBarTitle = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
      TextView actionBarTitleView = (TextView) getWindow().findViewById(actionBarTitle);
      if(actionBarTitleView != null){
          actionBarTitleView.setTypeface(typeFace);
      }
  </code></pre>
