/**
 * Provide default implementation to return a simple grid view.  Subclasses
 * can override to replace with their own layout.  If doing so, the
 * returned view hierarchy <em>must</em> have a GridView whose id
 * is {@link android.R.id#list android.R.id.list} and can optionally
 * have a sibling view id {@link android.R.id#empty android.R.id.empty}
 * that is to be shown when the grid is empty.
 *
 * <p>If you are overriding this method with your own custom content,
 * consider including the standard layout {@link android.R.layout#list_content}
 * in your layout file, so that you continue to retain all of the standard
 * behavior of ListFragment.  In particular, this is currently the only
 * way to have the built-in indeterminant progress state be shown.
