You are always calling displayView() with the selected index position in the list of NavDrawerItems. In the case where the user is logged out, there are only 2 items in the list. When the user chooses "login", the index position is 1, not 5.
You probably want to add one more variable to NavDrawerItem which represents which Fragment to show when the user selects that item. You could use either an int value which is then passed to displayView(), or your could use the class name of the Fragment to show.
EDIT: Add example code
In NavDrawerItem, you should have something like:
String title;
Icon icon;
add the following:
int thingToDo;
Then, in the constructor of NavDrawerItem, add an int parameter to the constructor to initialize the field, like this:
public NavDrawerItem(String title, Icon icon, int thingToDo) {
this.title = title;
this.icon = icon;
this.thingToDo = thingToDo;
}
change all your calls that create new NavDrawerItem instances to include the "thing to do", like this:
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1), 0));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1), 5));
Then, in SlideMenuClickListener.onItemClick() method, do this:
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// Get the item that was selected
NavDrawerItem item = navDrawerItems.get(position);
// display view for selected nav drawer item
displayView(item.thingToDo);
}
