Android HorizontalPaging Sample =================================== This sample shows how to implement tabs, using Fragments and a ViewPager. Introduction ------------ 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)`.
