i have code should allow me take value calculator , utilize further:

//-----------------this section creates keypad functionality (int o = 0; o < keybuttons.length; o++) { final int n = o; keybuttons[o] = (button) findviewbyid(data.keyids[n]); keybuttons[o].setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { seek { string tmp = texts[selectedit].gettext() .tostring(); switch (n) { case 3: texts[selectedit].settext(tmp.substring(0, tmp.length() - 1)); break; //get cursor position , delete char case 7: { // create intent realcalc. intent intent2 = new intent("uk.co.quarticsoftware.realcalc"); double x = 0; // set initial value (double). if (!texts[selectedit].gettext() .tostring() .equals("")) { x = double.valueof(texts[selectedit].gettext() .tostring()); } intent2.putextra("x", x); // launch calculator seek { startactivityforresult(intent2, 0); } grab (activitynotfoundexception e) { intent intent = new intent(intent.action_view, uri.parse("market://details?id=uk.co.nickfines.realcalc")); seek { startactivity(intent); } grab (activitynotfoundexception f) { // google play store app not available. } } break; } //open calculator case 11: { if (!tmp.contains("e")) texts[selectedit].settext(tmp + "" + keybuttons[n].gettext()); break; } //check e if dont have default case case 15: { tl.setvisibility(view.gone); break; } //simulate button default: { texts[selectedit].settext(tmp + "" + keybuttons[n].gettext()); //get cursor start , end , entire string // replace selected string button text //insert break; } } //end of switch } //end of seek grab (activitynotfoundexception e) { intent intent = new intent(intent.action_view, uri.parse("market://details?id=uk.co.nickfines.realcalc")); // calculator not installed } //calculator.num=n; grab (exception e) { stringwriter sw = new stringwriter(); e.printstacktrace(new printwriter(sw)); easyphysactivity.error = sw.tostring(); } } @override protected void onactivityresult(int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data); if (resultcode == activity.result_ok) { // user pressed ok. double value = data.getdoubleextra("x", double.nan); if (double.isnan(value)) { // calculation result "error". } else { // calculation result ok. } } else { // user pressed cancel or button. } } }); } //----------------------------------------

but doesn't these 3 lines:

@override protected void onactivityresult (int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data);

if delete @override becomes better, still shows error

super.onactivityresult(requestcode, resultcode, data);

what going wrong in here?

you cannot override onactivityresult within onclicklistener because not exist in base of operations class. move onactivityresult code within activity class, not onclicklistner.
