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)`.
