Android Spinner onItemSelected not being called inside Fragment -


i have activity calls several fragments. in 1 of fragments trying create dialog spinner programmatically , add menu option (in toolbar). manage make work (atleast view showing), onitemselected not getting called.

my code:

public class newsfeed extends fragment { private static final string tag = "tag"; private string tag; private arrayadapter<new> newsadapter; private arrayadapter<tag> tagsadapter; private spinner spinner;  public newsfeed() {     sethasoptionsmenu(true); }  public static newsfeed newinstance(string tag) {     newsfeed fragment = new newsfeed();     bundle args = new bundle();     args.putstring(tag, tag);     fragment.setarguments(args);     return fragment; }  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     if (getarguments() != null) {         tag = getarguments().getstring(tag);     }     sethasoptionsmenu(true);  }  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {     getactivity().settitle(tag);     navigationview activitynav = (navigationview) getactivity().findviewbyid(r.id.nav_view);     bottomnavigationview activitybuttomnav = (bottomnavigationview) getactivity().findviewbyid(r.id.navigation);     activitynav.setcheckeditem(r.id.nav_news);     activitybuttomnav.getmenu().getitem(1).setchecked(true);     view v = inflater.inflate(r.layout.fragment_news_feed, container, false);      //spinner related code           tagsadapter = new tagsadapter(getactivity(), android.r.layout.simple_spinner_item, (arraylist<tag>) applicationdata.tags);     spinner = new spinner(getactivity(), spinner.mode_dialog);     tagsadapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);     spinner.setprompt("filtrar por categoria:");     spinner.setadapter(tagsadapter);     spinner.setonitemselectedlistener(new adapterview.onitemselectedlistener() {         @override         public void onitemselected(adapterview<?> parent, view view, int position, long id) {          }          @override         public void onnothingselected(adapterview<?> parent) {          }     });      newsadapter = new newsadapter(getactivity().getapplicationcontext(), 0, (arraylist<new>) applicationdata.news);     listview listview = (listview) v.findviewbyid(r.id.listview);     listview.setonitemclicklistener(new adapterview.onitemclicklistener() {         @override         public void onitemclick(adapterview<?> adapter, view view, int position, long id) {             fragmenttransaction ft = getactivity().getsupportfragmentmanager().begintransaction();             newsdisplay nd = newsdisplay.newinstance(tag, applicationdata.news.get(position).getnewsurl());             ft.addtobackstack(null);             ft.replace(r.id.fragmentcontent, nd).commit();         }     });     listview.setadapter(newsadapter);     return v; }  @override public void oncreateoptionsmenu(menu menu, menuinflater inflater) {     inflater.inflate(r.menu.main, menu);     super.oncreateoptionsmenu(menu, inflater); }  @override public boolean onoptionsitemselected(menuitem item) {     int id = item.getitemid();      if (id == r.id.filter_category) {          //for showing spinner         spinner.performclick();         return true;     }     return super.onoptionsitemselected(item); }

}

already tried:

to make newsfeed implementing onitemselectedlistener.

to create onitemselectedlistener object inside setonitemselectedlistener.

could give me help? might have being fragment , toolbar in activity.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
