@override public view getview(final int position, view convertview, final viewgroup parent) { final myholder holder; if (convertview == null) { convertview = layoutinflater.inflate(r.layout.list_row, null); holder = new myholder(); holder.vocabs = (textview) convertview.findviewbyid(r.id.textviewvocabs); holder.points = (textview) convertview.findviewbyid(r.id.textviewpoints); holder.tick = (imagebutton) convertview.findviewbyid(r.id.tick); holder.cross = (imagebutton) convertview.findviewbyid(r.id.cross); convertview.settag(holder); } else { holder = (myholder) convertview.gettag(); } holder.id = id.get(position); holder.vocabs.settext(vocabs.get(position)); holder.points.settext(points.get(position) + ""); holder.tick.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { //toast.maketext(parent.getcontext(), "yes... :d ... learn :d", toast.length_short).show(); points.set(position, points.get(position) + 1); database.execsql("update vocabs set points=" + points.get(position) + " id=" + id.get(position) + ";"); notifydatasetchanged(); } }); holder.cross.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { //toast.maketext(parent.getcontext(), "yes... :d ... learn :d", toast.length_short).show(); if (points.get(position) != 0) { points.set(position, points.get(position) - 1); database.execsql("update vocabs set points=" + points.get(position) + " id=" + id.get(position) + ";"); } notifydatasetchanged(); } }); convertview.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { toast.maketext(parent.getcontext(), means.get(position), toast.length_long).show(); } }); final view finalconvertview = convertview; convertview.setonlongclicklistener(new view.onlongclicklistener() { @override public boolean onlongclick(view v) { //popup-menu delete item. popupmenu popupmenu = new popupmenu(parent.getcontext(),finalconvertview); popupmenu.getmenuinflater().inflate(r.menu.popup_menu, popupmenu.getmenu()); popupmenu.show(); popupmenu.setonmenuitemclicklistener(new popupmenu.onmenuitemclicklistener() { @override public boolean onmenuitemclick(menuitem item) { if (item.gettitle().equals("delete")) { database.execsql("delete vocabs id=" + holder.id + ";"); id.remove(position); vocabs.remove(position); means.remove(position); points.remove(position); notifydatasetchanged(); } return false; } }); //toast.maketext(parent.getcontext(), "onlongclickfunction! " + position, toast.length_long).show(); return false; } }); return convertview; } i work itellij idea 13.1.4. add appcompat supports popup_menu on apis older 11. when run application, everythings ok. when long click on item in listview below error:

i suspect you're not getting correct view when calling popupmenu constructor.
change code from:
popupmenu popupmenu = new popupmenu(parent.getcontext(),finalconvertview); to:
popupmenu popupmenu = new popupmenu(parent.getcontext(), v); i admit maybe same view depending on layout design. suggested code under more accurate. view parameter v points row item in listview.
please post menu xml r.menu.popup_menu also.
