| This sample shows how to implement tabs, using Fragments and a ViewPager. |
| </description> |
| <intro> |
| This sample implements tabs using the deprecated [ActionBar.TabListener][1]. It uses [ViewPager][2] and |
| [FragmentPagerAdapter][3] to handle swiping between tabs and displaying the selected tab content. |
| |
| |
| 1. Create an Activity that extends [FragmentActivity][4], with a [ViewPager][2] for its layout. |
| 2. Implement [ActionBar.TabListener][1] interface. |
| 3. Create a class that extends [FragmentPagerAdapter][3] and override its `getItem(int position)`, |
| `getCount()` and `getPageTitle(int position)` methods. |
| 4. In the `onCreate(Bundle savedInstanceState)` method of your activity, set navigation mode to tabs for the |
| ActionBar using `setNavigationMode(ActionBar.NAVIGATION_MODE_TABS)`. Note: This is DEPRECATED as of Android |
| Lollipop. |
| 5. Set your custom [FragmentPagerAdapter][3] on your [ViewPager][2]. |
| 6. Implement `setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener())` on your [ViewPager][2] to |
| know the selected tab, so you can update your ActionBar with `setSelectedNavigationItem(position)`. |
