title: How to set the titles in a ViewPager PagerTitleStrip instantly
body: <p>I know that I can override the <code>getPageTitle()</code> method of <code>FragmentPagerAdapter</code>:</p>
  
  <pre><code>@Override
  public CharSequence getPageTitle(int position) {
      return "myTitle";
  }
  </code></pre>
  
  <p>...but I'd like to change to page titles on a <code>CursorLoader</code> callback:</p>
  
  <pre><code>@Override
  public void onLoadFinished(Loader&lt;Cursor&gt; loader, Cursor cursor) {
              // How to set the page title here? I miss something like:
              //     mPagerTitleStrip.setTitle(1, "My Title");
              // or: mFragmentPagerAdapter.setTitle(1, "My Title");
  }
  </code></pre>
