I couldnt make it work with popup but tried alert box and was implementation became very easy.

here is the code for alert box: http://www.androidsnippets.com/prompt-user-input-with-an-alertdialog

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    final View popupView = inflater.inflate(R.layout.popup2, null);
    final PopupWindow popup2 = new PopupWindow(popupView,
          RadioGroup.LayoutParams.MATCH_PARENT,
          RadioGroup.LayoutParams.MATCH_PARENT);
    popup2.setFocusable(true);
    popup2.showAtLocation(view, Gravity.CENTER, 0, 0);
}
