1 line annon inner class array initialisation because I want to be able to add & remove but I'm too lazy to extend BaseAdapter.

Crazy Array Init

public class NavDrawerArrayAdapter extends ArrayAdapter<String> {
    public NavDrawerArrayAdapter(final Context context) {
        super(context, android.R.layout.simple_list_item_activated_1, android.R.id.text1,
                new ArrayList<String>() {{
                    add(context.getString(R.string.nav_drawer_section_explore));
                    add(context.getString(R.string.nav_drawer_section_rewards));
                    add(context.getString(R.string.nav_drawer_section_offers));
                    add(context.getString(R.string.nav_drawer_section_events));
                }});
        refresh();
    }

    public void refresh() {
        if (MyApplication.isSignedIn()) {
            remove(getContext().getString(R.string.nav_drawer_section_sign_in_up));
            add(getContext().getString(R.string.nav_drawer_section_account));
        } else {
            add(getContext().getString(R.string.nav_drawer_section_sign_in_up));
            remove(getContext().getString(R.string.nav_drawer_section_account));
        }
    }
}
