This sample demonstrates how to create swipe views with tabs. Users can swipe
|
|
between tabs, or click on a tab title to jump to the section. Some tabs are
|
|
scrollable, meaning that users can scroll horizontally through the tab strip and
|
|
select a tab.

This sample use combination of [ViewPager][1] and [TabLayout][2] to create swipe
|
|
views with tabs.
|
|
|
|
In order to use ViewPager, you first need to implement a PagerAdapter to feed
|
|
its content. In this sample, we use [FragmentPagerAdapter][3] and
|
|
[FragmentStatePagerAdapter][4]. FragmentPagerAdapter is useful when you have a
|
|
limited number of fixed pages. FragmentStatePagerAdapter can be used for
|
|
ViewPager with a lot of pages as it can save and restore state of Fragments
|
|
inside of it in a memory-efficient way.
|
|
|
|
Using TabLayout with ViewPager is simple. Just call the method
|
|
[setupWithViewPager(ViewPager)][5], and the TabLayout generates corresponding
|
|
tabs for the ViewPager. The titles are populated from [getPageTitle(int)][6]
|
|
method of your ViewPager adapter.
