I have implemented a fragment activity with a nav drawer, which works well for clicking and loading the fragments that are listed in the nav drawer.
When you click an item in my nav drawer it loads the new fragment and highlights the correct list item in the nav drawer. The problem is, in those selected fragments if you click on a button which loads a new fragment that is not listed in the nav drawer, it keeps the last item in the nav drawer highlighted and you can not click it again while it is highlighted.
My MainDrawer2 fragment activity is:
public class MainDrawer2 extends FragmentActivity
{
private static final String EXTRA_NAV_ITEM = "extraNavItem";
private static final String STATE_CURRENT_NAV = "stateCurrentNav";
private ActionBarDrawerToggle mDrawerToggle;
