java - Fragment content does not show up until I switch it and select it again -

i've got problem android app: fragment content doesn't show until switch , select again. should load @ fragment start list of cards.

here got oncreate method of fragment loads everything:

@override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     bundle = this.getarguments();     debts = bundle.getparcelablearraylist("list");     adapter =  new cardadapter(getactivity(), android.r.color.holo_blue_dark);      (int i=0; i<debts.size();++i) {         debt d = debts.get(i);         card card = new card(d.getseconduser(),d.getsubject());         adapter.add(card);     }   } 

and here onactivitycreated method set adapter list:

@override public void onactivitycreated(bundle savedinstancestate) {     super.onactivitycreated(savedinstancestate);      cardlistview list = (cardlistview) getview().findviewbyid(r.id.newcard);     list.setcardtheme(cardtheme.light);     list.setadapter(adapter); } 

it works if use arraylist of cards loaded, not way. tried everything... thank much.

update: tried solutions gave me, keeps happening, code now:

@override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     bundle = this.getarguments();     debts = bundle.getparcelablearraylist("list");     adapter =  new cardadapter(getactivity(), android.r.color.holo_blue_dark);      (int i=0; i<debts.size();++i) {         debt d = debts.get(i);         card card = new card(d.getseconduser(),d.getsubject());         adapter.add(card);     }   }  @override public view oncreateview(layoutinflater inflater, viewgroup container,                          bundle savedinstancestate) {      view rootview = inflater.inflate(r.layout.fragment_debts, container,             false);      cardlistview list = (cardlistview) rootview.findviewbyid(r.id.newcard);     list.setcardtheme(cardtheme.light);     list.setadapter(adapter);      return rootview; } 

you should initialize cardlistview inside oncreateview() method. oncreateview() gets called before onactivitycreated() method. oncreateview() should point when view of fragment initialized.

@override public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {      //use layout file instead of r.layout.fragment_main     view rootview = inflater.inflate(r.layout.fragment_main, container,                 false);      cardlistview list = rootview.findviewbyid(r.id.newcard);     list.setcardtheme(cardtheme.light);     list.setadapter(adapter); } 

please take @ the lifecycle of fragments.
