It uses [ViewPager][2] and 57[FragmentPagerAdapter][3] to handle swiping between tabs and displaying the selected tab content. 58 59 601. Create an Activity that extends [FragmentActivity][4], with a [ViewPager][2] for its layout. 612. Implement [ActionBar.TabListener][1] interface. 623. Create a class that extends [FragmentPagerAdapter][3] and override its `getItem(int position)`, 63`getCount()` and `getPageTitle(int position)` methods. 644. In the `onCreate(Bundle savedInstanceState)` method of your activity, set navigation mode to tabs for the 65ActionBar using `setNavigationMode(ActionBar.NAVIGATION_MODE_TABS)`. Note: This is DEPRECATED as of Android 66Lollipop. 675. Set your custom [FragmentPagerAdapter][3] on your [ViewPager][2]. 686. Implement `setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener())` on your [ViewPager][2] to 69know the selected tab, so you can update your ActionBar with `setSelectedNavigationItem(position)`. 70 71[1]: http://developer.android.com/reference/android/support/v7/app/ActionBar.TabListener.html 72[2]: http://developer.android.com/reference/android/support/v4/view/ViewPager.html 73[3]: http://developer.android.com/reference/android/support/v4/app/FragmentPagerAdapter.html 74[4]: http://developer.android.com/reference/android/support/v4/app/FragmentActivity.html 75 </intro> 76 </metadata> 77 78</sample> 79
