title: Fragment Tabs inside Fragment
body: <p>I have in my Main Activity an Action bar navigation using tabs using Fragments (with Material Design), as below which works well, but now I wish to have Tab navigation within my Fragments...</p>
  
  <pre><code>// Add Fragments to Tabs in Main Activity
  private void setupViewPager(ViewPager viewPager) {
      Adapter adapter = new Adapter(getSupportFragmentManager());
      adapter.addFragment(new FeedsFragment(), "Latest Updates");
      adapter.addFragment(new ClubTeamsFragment(), "Club Teams");
      adapter.addFragment(new FixturesFragment(), "Fixtures");
      adapter.addFragment(new ResultsFragment(), "Results");
      adapter.addFragment(new ClubFieldsFragment(), "Club Fields");
      viewPager.setAdapter(adapter);
  }
  </code></pre>
  
  <p>I'm pretty sure that TabHost is now deprecated.</p>
  
  <p>I wish to achieve the attached image. The blue tabs are at the Main Activity level and the gray date tabs are in the selected fragment view.</p>

  <p>I have read a few post about using Tab Host or Fragment Activity, or do I use Activity that is extended to Fragment?</p>
