Enclosing class:

ViewPagerSample

public static class ViewPagerSample.PagerAdapter
extends android.support.v4.app.FragmentPagerAdapter

This is a helper class that implements the management of tabs and all details of connecting a ViewPager with associated TabHost. It relies on a trick. Normally a tab host has a simple API for supplying a View or Intent that each tab will show. This is not sufficient for switching between pages. So instead we make the content part of the tab host 0dp high (it is not shown) and the TabsAdapter supplies its own dummy view to show as the tab content. It listens to changes in tabs, and takes care of switch to the correct paged in the ViewPager whenever the selected tab changes.
