protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); final layoutinflater inflater = (layoutinflater) this.getsystemservice(context.layout_inflater_service); final popupwindow pw = new popupwindow( inflater.inflate(r.layout.activity_setting, null, false), 200, 200, true); setcontentview(r.layout.activity_memo); button bt1 = (button) findviewbyid(r.id.button1); button bt2 = (button) findviewbyid(r.id.btnback); bt1.setonclicklistener(new button.onclicklistener() { @override public void onclick(view v) { view layout = inflater.inflate(r.layout.activity_memo, listview); showatlocation(layout, gravity.center, 0, 0); } }); bt1.setonclicklistener(new button.onclicklistener() { @override public void onclick(view v) { pw.dismiss(); } }); }

you can have background activity listener of popup window. when button clicked in popup window, phone call method onbuttonclick(string text) on listener. since activity listener, text.

android return-value popupwindow
