any ideas?

help appreciated.

first of all, quite easy.

you have add attribute actionbar item.

android:onclick="openpopup" 

openpopup popup method.

then, in mainactivity way supposed extend actionbaractivity
have add method called onclick.

public void openpopup(menuitem item){        point p;       p.x = 0;       p.y = 0;       showpopup(mainactivity.this, p);       toast.maketext(this, "popup should open", toast.length_long).show();   }  

and of course showpopup method.

private void showpopup(final activity context, point p) {     // inflate popup_layout.xml    linearlayout viewgroup = (linearlayout) context.findviewbyid(r.id.popup);    layoutinflater layoutinflater = (layoutinflater) context      .getsystemservice(context.layout_inflater_service);    view layout = layoutinflater.inflate(r.layout.popup_layout, viewgroup);     // creating popupwindow    final popupwindow popup = new popupwindow(context);    popup.setcontentview(layout);    popup.setwidth(viewgroup.layoutparams.wrap_content);    popup.setheight(viewgroup.layoutparams.wrap_content);    popup.setfocusable(true);     popupwidth = popup.getwidth();     // clear default translucent background    popup.setbackgrounddrawable(new bitmapdrawable(this.getresources()));     // displaying popup @ specified location.    popup.showatlocation(layout, gravity.no_gravity, p.x, p.y);     // getting reference close button, , close popup when clicked.    button close = (button) layout.findviewbyid(r.id.close);    close.setonclicklistener(new onclicklistener() {       @override      public void onclick(view v) {        popup.dismiss();      }    }); } 

that's it.
