-

i trying fill list in fragment return null object reference.(attempt invoke virtual method 'android.view.view android.view.view.findviewbyid(int)' on null object reference) there code:

    public void oncreate(bundle savedinstancestate) {          super.oncreate(savedinstancestate);          person.add(new gender("35ae111", false, "60 km/h"));          final listview listview= (listview)getview().findviewbyid(r.id.liste);          customadapter customadapter=new customadapter(getactivity(), kisiler);         listview.setadapter(customadapter);     }      @override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {         // inflate layout fragment         return inflater.inflate(r.layout.fragment_all_vehicles, container, false);     } }

you need move things need view oncreateview:

public void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);      person.add(new gender("35ae111", false, "60 km/h")); }  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {     // inflate layout fragment     view view = inflater.inflate(r.layout.fragment_all_vehicles, container, false);     final listview listview= (listview)view.findviewbyid(r.id.liste);      customadapter customadapter=new customadapter(getactivity(), kisiler);     listview.setadapter(customadapter);     return view; }
