java - Date/Time Pickers not giving changed values -

i created alertdialog contains both datepicker , timepicker inside of it. date , time pickers initialized each time opened whatever date on text of button used open it. when user clicks "set" button in dialog box supposed update text on button selected date , time keeps @ old date , time.

it appears using datepicker.getyear() , other methods isn't getting selected data in picker because made toast test , displayed old information only.

here code:

startdate.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {              //get date button text             calendar timeinbutton = calendar.getinstance();             simpledateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm", locale.us);             try {                 timeinbutton.settime(sdf.parse(startdate.gettext().tostring()));             } catch (parseexception e) {                 e.printstacktrace();             }             int pyear = timeinbutton.get(calendar.year);             int pmonth = timeinbutton.get(calendar.month);             int pday = timeinbutton.get(calendar.day_of_month);             int phour = timeinbutton.get(calendar.hour_of_day);             int pminute = timeinbutton.get(calendar.minute);              final view dialogview = view.inflate(myactivity.this, r.layout.date_picker_dialog, null);              final datepicker datepicker = (datepicker) dialogview.findviewbyid(r.id.date_picker);             datepicker.init(pyear, pmonth, pday, null);              final timepicker timepicker = (timepicker) dialogview.findviewbyid(r.id.time_picker);             timepicker.setcurrenthour(phour);             timepicker.setcurrentminute(pminute);              alertdialog.builder dateandtimepickerdialog = new alertdialog.builder(addcashgame.this);             dateandtimepickerdialog.settitle("select starting date , time");              layoutinflater inflater = addcashgame.this.getlayoutinflater();              dateandtimepickerdialog.setview(inflater.inflate(r.layout.date_picker_dialog, null));             dateandtimepickerdialog.setpositivebutton("set", new dialoginterface.onclicklistener() {                 @override                 public void onclick(dialoginterface dialog, int which) {                     int newyear = datepicker.getyear();                     int newmonth = datepicker.getmonth() + 1;                     int newday = datepicker.getdayofmonth();                     int newhour = timepicker.getcurrenthour() % 12;                     string newminute = formatter.format(timepicker.getcurrentminute());                     string newamorpm = timepicker.getcurrenthour() % 12 <= 12 ? " am" : " pm";                      string newtime = newmonth + "/" + newday + "/" + newyear + "   " + newhour + ":" + newminute + newamorpm;                      startdate.settext(newtime);                     toast.maketext(addcashgame.this, newtime + "",toast.length_short).show();                 }             });             dateandtimepickerdialog.setnegativebutton("cancel", null);             dateandtimepickerdialog.show();          }     }); 

this happening because you're pointing alertdialog view new one, instead of 1 you've inflated in line:

final view dialogview = view.inflate(myactivity.this, r.layout.date_picker_dialog, null); 

the first view you've inflated contains both datepicker , timepicker set right time, while new 1 set, default, calendar.getinstance().

change line:

dateandtimepickerdialog.setview(inflater.inflate(r.layout.date_picker_dialog, null)); 

to line:

dateandtimepickerdialog.setview(dialogview);
