@override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main);      listview = (listview) findviewbyid(r.id.listview);     adapter = new myadapter(getapplicationcontext());  }  @override protected void onresume() {     super.onresume();     connecttodatabase(); }  private void connecttodatabase() {     //create database         listview.setadapter(adapter);     } 

my adapter:

        @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;     }

what wrong???

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.
