// Clear the data private void showpopup () {layoutinflater mlayoutinflater = (layoutinflater) getsystemservice (layout_inflater_service); viewgroup mview = (viewgroup) mlayoutinflater. inflate (R. layout. soft_calendar_popup, null, true); Final popupwindow = new popupwindow (mview, layoutparams. wrap_content, layoutparams. wrap_content, true); Final radiobutton radio1 = (radiobutton) mview. findviewbyid (R. id. radio0); Final radiobutton Radio2 = (radiobutton) mview. findviewbyid (R. id. radio1); Final radiobutton radio3 = (radiobutton) mview. findviewbyid (R. id. radio2); button btn1 = (button) mview. findviewbyid (R. id. button1); btn1.setonclicklistener (New onclicklistener () {@ overridepublic void onclick (view v) {// The operation popupwindow implemented by the OK button. dismiss () ;}}); button btn2 = (button) mview. findviewbyid (R. id. button2); btn2.setonclicklistener (New onclicklistener () {@ overridepublic void onclick (view v) {// cancel the operation popupwindow implemented by the button. dismiss () ;}}); popupwindow. setbackgrounddrawable (New bitmapdrawable (); popupwindow. showatlocation (findviewbyid (R. id. relativelayout1), gravity. center | gravity. center, 0, 0); // popupwindow is displayed in the center of the screen. update ();}
