android - ListView items repeat in BaseAdapter -

i'm pulling data , loading baseadapter list view. currently, items in listview same last item added, list looks this:

item 3 item 3 item 3 

instead of:

item 1 item 2 item 3 

i've checked on data sources, , data that's loaded source unique each time. think there's somehting wrong baseadapter, i'm not sure is. here's baseadapter:

baseadapter.java

arraylist<threadlistdata> mylist = new arraylist<>(); layoutinflater inflater; context context;  public threadbaseadapter(context context, arraylist<threadlistdata> mylist) {     this.context = context;     inflater = layoutinflater.from(this.context);     this.mylist = mylist; }  @override public int getcount() {     return mylist.size(); }  @override public threadlistdata getitem(int position) {     return mylist.get(position); }  @override public long getitemid(int position) {     return 0; }  @override public view getview(int position, view convertview, viewgroup parent) {      if (convertview == null) {         layoutinflater inflater = layoutinflater.from(this.context);         convertview = inflater.inflate(r.layout.listitem_newthread, parent, false);      }      threadlistdata listdata = getitem(position);      textview name = (textview)convertview.findviewbyid(r.id.name_newthread);     textview username = (textview)convertview.findviewbyid(r.id.username_newthread);      name.settext(listdata.getname());     username.settext(listdata.getname());      parseimageview profile = (parseimageview)convertview.findviewbyid(r.id.profilepicture);      bitmaptask task = new bitmaptask(listdata.getimage());      task.execute(profile);      return convertview; } 

i'll start baseadapter, , can show more code if requested. appreciated!

you missed return position

modifiy getitemid as

@override public long getitemid(int position) {     return position; }
