android - Spinner onItemSelected does not work - 


private spinner spinnermonth;  public view oncreateview(layoutinflater inflater         , @nullable viewgroup container         , @nullable bundle savedinstancestate) {     super.oncreateview(inflater, container, savedinstancestate);     _view = inflater.inflate(r.layout.fragment_spinnermonth, container, false);      // month     spinnermonth = (spinner) _view.findviewbyid(r.id.spinnermonth);     spinnermonth.setadapter(monthadapter);     spinnermonth.setselection(_selectedmonth - 1);     return _view; }  private void savedata() {     spinnermonth.setonitemselectedlistener(new adapterview.onitemselectedlistener() {         @override         public void onitemselected(adapterview<?> adapterview, view view, int i, long l) {         log.d("month",i);                 }          @override         public void onnothingselected(adapterview<?> adapterview) {         }     }); }

my codes above. if determine global spinner, onitemselected not work. if determine local spinner, work. why happen? need global spinner.

find solution

public view oncreateview(layoutinflater inflater         , @nullable viewgroup container         , @nullable bundle savedinstancestate) {     super.oncreateview(inflater, container, savedinstancestate);     _view = inflater.inflate(r.layout.fragment_spinnermonth, container, false);      // month     spinnermonth = (spinner) _view.findviewbyid(r.id.spinnermonth);     spinnermonth.setadapter(monthadapter);     spinnermonth.setselection(_selectedmonth - 1);     spinnermonth.setonitemselectedlistener(new adapterview.onitemselectedlistener() {         @override         public void onitemselected(adapterview<?> adapterview, view view, int i, long l) {         log.d("month",i);                 }          @override         public void onnothingselected(adapterview<?> adapterview) {         }     });     return _view; }
