-/**
- * Implementation of {@link android.support.v4.view.PagerAdapter} that
- * uses a {@link Fragment} to manage each page. This class also handles
- * saving and restoring of fragment's state.
- *
- * <p>This version of the pager is more useful when there are a large number
- * of pages, working more like a list view.  When pages are not visible to
- * the user, their entire fragment may be destroyed, only keeping the saved
- * state of that fragment.  This allows the pager to hold on to much less
- * memory associated with each visited page as compared to
- * {@link FragmentPagerAdapter} at the cost of potentially more overhead when
- * switching between pages.
- *
- * <p>When using FragmentPagerAdapter the host ViewPager must have a
- * valid ID set.</p>
- *
- * <p>Subclasses only need to implement {@link #getItem(int)}
- * and {@link #getCount()} to have a working adapter.
- *
- * <p>Here is an example implementation of a pager containing fragments of
- * lists:
- *
- * {@sample development/samples/Support4Demos/src/com/example/android/supportv4/app/FragmentStatePagerSupport.java
- *      complete}
- *
- * <p>The <code>R.layout.fragment_pager</code> resource of the top-level fragment is:
- *
- * {@sample development/samples/Support4Demos/res/layout/fragment_pager.xml
- *      complete}
- *
- * <p>The <code>R.layout.fragment_pager_list</code> resource containing each
- * individual fragment's layout is:
- *
- * {@sample development/samples/Support4Demos/res/layout/fragment_pager_list.xml
- *      complete}
