          case 0:
          return getString(R.string.title_section1).toUpperCase(l);
          case 1:
          return getString(R.string.title_section2).toUpperCase(l);
          case 2:
          return getString(R.string.title_section3).toUpperCase(l);

          }
          return null;
      }
  
      }
  </code></pre>
  
  <p>and in onCreate:</p>
  
  <pre><code>mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
  
      // Set up the ViewPager with the sections adapter.
      mViewPager = (ViewPager) findViewById(R.id.pager);
      mViewPager.setAdapter(mSectionsPagerAdapter);
  </code></pre>
