the code using pass information , pick follows:

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_drawer);      mnavigationdrawerfragment = (navigationdrawerfragment)             getsupportfragmentmanager().findfragmentbyid(r.id.navigation_drawer);     mtitle = gettitle();      arraylist<string> menuitems = new arraylist<string>();     menuitems.add("test");      bundle bundle = new bundle();     bundle.putstringarraylist("edttext", menuitems);     /* set fragmentclass arguments */     navigationdrawerfragment fragobj = new navigationdrawerfragment();     fragobj.setarguments(bundle);      // set drawer.     mnavigationdrawerfragment.setup(             r.id.navigation_drawer,             (drawerlayout) findviewbyid(r.id.drawer_layout));  } 

and code using pick new arguments is:

@override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {         arraylist<string> strtext = getarguments().getstringarraylist("edttext");         mdrawerlistview = (listview) inflater.inflate(                 r.layout.fragment_navigation_drawer, container, false);         mdrawerlistview.setonitemclicklistener(new adapterview.onitemclicklistener() {             @override             public void onitemclick(adapterview<?> parent, view view, int position, long id) {                 selectitem(position);             }         });         mdrawerlistview.setadapter(new arrayadapter<string>(                 getactionbar().getthemedcontext(),                 android.r.layout.simple_list_item_activated_1,                 android.r.id.text1,                 strtext));         mdrawerlistview.setitemchecked(mcurrentselectedposition, true);         return mdrawerlistview;     } 

any appreciated!

you can use class static arraylist property

public class values {     public static arraylist<string> myarraylist; } 

in activity:

arraylist<string> menuitems = new arraylist<string>(); values.myarraylist = menuitems; 

in fragment

arraylist<string> strtext = values.myarrayadapter;
