title: How to add different fragments to the same ViewPager?
body: <p>While scrolling horizontally in viewpager fragment project it shows only one fragment (fragment_main.xml) for three tabs. how to link a second fragment (fragment2.xml) when the user scrolls horizontally.</p>
  
  <p>Here is my codes</p>
  
  <p><strong>MainActivity</strong></p>
  
  <pre><code>public class MainActivity extends ActionBarActivity implements ActionBar.TabListener {

   * The {@link android.support.v4.view.PagerAdapter} that will provide
   * fragments for each of the sections. We use a
   * {@link FragmentPagerAdapter} derivative, which will keep every
   * loaded fragment in memory. If this becomes too memory intensive, it
   * may be best to switch to a
   * {@link android.support.v4.app.FragmentStatePagerAdapter}.
