android - Empty Rows in listview -


whenever add new value in array creates 2 rows 1 empty row in listview. when delete value in array value removed both row still exists.

protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.listcontact);               sharedpreferences=getsharedpreferences(preferences,context.mode_private);         for(int i=1;i<=n+1;i++) {         string st=sharedpreferences.getstring(string.valueof(i), "");         conact_list.add(st);         } arrayadapter adapter=new arrayadapter<string>(getbasecontext(),android.r.layout.simple_list_item_1,conact_list); listview cv= (listview) findviewbyid(r.id.listview); cv.setadapter(adapter); }

below opinion:

case 1: check number of data object matching item in view. mean in for(int i=1;i<=n+1;i++ check value of n, equal number items displayed in view. if 2 values same, should check data in preference again.

otherwise, go case 2 : check adapter, in adapter should check getview , getcount method. number value returned getcount must same number of data object.
