android - ListView Adapter calling getView with the same index 3 times despite there being 17 items in arraylist -
as title says, adapter doesn't work. i've given arraylist of string arrays. arraylist contains 17 string arrays. result should 17 rows in list view. alas, fails me.
@override public view getview(int index, view arg1, viewgroup parent) { layoutinflater inflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service); view view = inflater.inflate(r.layout.courses_list, parent, false); textview modulecode = (textview) view.findviewbyid(r.id.modulecode); modulecode.settext(list.get(index)[0]); log.i("list-get", integer.tostring(index)); textview modulename = (textview) view.findviewbyid(r.id.modulename); modulename.settext(list.get(index)[1]); textview modulecredits = (textview) view.findviewbyid(r.id.modulecredits); modulecredits.settext(list.get(index)[2]); checkbox c = (checkbox) view.findviewbyid(r.id.modulecheck); c.setchecked(true); return view; } this logcat outputs:
04-29 17:31:13.818 14509-14509/com.example.thing i/list-get﹕ 0 04-29 17:31:13.830 14509-14509/com.example.thing i/list-get﹕ 0 04-29 17:31:13.834 14509-14509/com.example.thing i/list-get﹕ 0 this listview looks in xml (with match_parent added):
