android - Custom array adapter doesn't work in DialogFragment -

i want populate list view custom array adapter, looks getview() never called. below code, part creates dialog:

@override public dialog oncreatedialog(bundle savedinstancestate) {     // use builder class convenient dialog construction     alertdialog.builder builder = new alertdialog.builder(getactivity());     builder.setpositivebutton("delete", new dialoginterface.onclicklistener() {         public void onclick(dialoginterface dialog, int id) {             //do deletion         }     })             .setnegativebutton(r.string.cancel, new dialoginterface.onclicklistener() {                 public void onclick(dialoginterface dialog, int id) {                     // user cancelled dialog                 }             });     builder.settitle("dialog title").setview(getcustomview());     return builder.create(); } 

this part creates view, commented on works, doesn't

public view getcustomview(){     layoutinflater inflater = (layoutinflater) getactivity().getsystemservice(context.layout_inflater_service);     view view  = inflater.inflate(r.layout.dialog_delete_option, null);     listview listview = (listview) view.findviewbyid(r.id.listdeloptions);      /*this default array adapter, works */     list<string> list = new arraylist<string>();     list.add("del one");     list.add("del all");     arrayadapter<string> defaultadapter = new arrayadapter<string>(getactivity(),             android.r.layout.simple_list_item_single_choice, list);      /*this custom adapter, not working */     madapter = new deleteadapter(getactivity(),0); //last int not used since     //know layout inflate      //not working     //listview.setadapter(madapter);     //madapter.notifydatasetchanged();      //working     listview.setadapter(defaultadapter);     return view; } 

this custom array adapter, getview relevant, post here whole class in case.

public static class deleteadapter extends arrayadapter{     private final int mlayoutid;     private int mcheckpos;     context mcontext;     string [] mbuttondescription;      public deleteadapter(context context, int resource) {         super(context, resource);         mlayoutid= r.layout.delete_list_item_view;         mcontext = context;         mcheckpos = 0;         mbuttondescription = new string[3];         mbuttondescription[0] = context.getstring(r.string.del_only_this_event);         mbuttondescription[1] = context.getstring(r.string.del_this_and_future_events);         mbuttondescription[2] = context.getstring(r.string.del_all_events);      }       @override     public view getview(int position, view convertview, viewgroup parent) {         view view =convertview;         if (view==null){             view =  view.inflate(mcontext,mlayoutid, null);         }         radiobutton button = (radiobutton) view.findviewbyid(r.id.rddeloption);         button.settag(new integer(position));         button.setoncheckedchangelistener(checkedchangelistener);         if (position== mcheckpos)             button.setchecked(true);         else             button.setchecked(false);         button.settext(mbuttondescription[position]);         return  view;     }      compoundbutton.oncheckedchangelistener checkedchangelistener = new compoundbutton.oncheckedchangelistener() {         @override         public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) {             if (ischecked){                 mcheckpos =  (integer) buttonview.gettag();//tag position             }         }     };       public int getselecteditem(){         return mcheckpos;     }  } 

what's wrong deleteadapter? thanks.
