8*d353a188SXin Li------------
9*d353a188SXin Li
10*d353a188SXin LiThis sample implements tabs using the deprecated [ActionBar.TabListener][1]. It uses [ViewPager][2] and
11*d353a188SXin Li[FragmentPagerAdapter][3] to handle swiping between tabs and displaying the selected tab content.
12*d353a188SXin Li
13*d353a188SXin Li
14*d353a188SXin Li1. Create an Activity that extends [FragmentActivity][4], with a [ViewPager][2] for its layout.
15*d353a188SXin Li2. Implement [ActionBar.TabListener][1] interface.
16*d353a188SXin Li3. Create a class that extends [FragmentPagerAdapter][3] and override its `getItem(int position)`,
17*d353a188SXin Li`getCount()` and `getPageTitle(int position)` methods.
18*d353a188SXin Li4. In the `onCreate(Bundle savedInstanceState)` method of your activity, set navigation mode to tabs for the
19*d353a188SXin LiActionBar using `setNavigationMode(ActionBar.NAVIGATION_MODE_TABS)`. Note: This is DEPRECATED as of Android
20*d353a188SXin LiLollipop.
21*d353a188SXin Li5. Set your custom [FragmentPagerAdapter][3] on your [ViewPager][2].
22*d353a188SXin Li6. Implement `setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener())` on your [ViewPager][2] to
23*d353a188SXin Liknow the selected tab, so you can update your ActionBar with `setSelectedNavigationItem(position)`.
