- *

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 android.support.v4.app.FragmentPagerAdapter} at the cost of potentially more overhead when - * switching between pages. - *

- *

When using FragmentPagerAdapter the host ViewPager must have a - * valid ID set.

- *

Subclasses only need to implement {@link #getItem(int)} - * and {@link #getCount()} to have a working adapter. - *
