/**
|
||||
* Implementation of {@link PagerAdapter} that
|
||||
* uses a {@link Fragment} to manage each page. This class also handles
|
||||
* saving and restoring of fragment's state.
|
||||
* <p/>
|
||||
* <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/>
|
||||
* <p>When using FragmentPagerAdapter the host ViewPager must have a
|
||||
* valid ID set.</p>
|
||||
* <p/>
|
||||
* <p>Subclasses only need to implement {@link #getItem(int)}
|
||||
* and {@link #getCount()} to have a working adapter.
|
||||
* <p/>
|
||||
* <p>Here is an example implementation of a pager containing fragments of
|
||||
* lists:
|
||||
* <p/>
|
||||
* {@sample development/samples/Support13Demos/src/com/example/android/supportv13/app/FragmentStatePagerSupport.java
|
||||
* complete}
|
||||
* <p/>
|
||||
* <p>The <code>R.layout.fragment_pager</code> resource of the top-level fragment is:
|
||||
* <p/>
|
||||
* {@sample development/samples/Support13Demos/res/layout/fragment_pager.xml
|
||||
* complete}
|
||||
* <p/>
|
||||
* <p>The <code>R.layout.fragment_pager_list</code> resource containing each
|
||||
* individual fragment's layout is:
|
||||
* <p/>
|
||||
* {@sample development/samples/Support13Demos/res/layout/fragment_pager_list.xml
