i'm creating form consists of edittexts launch datepickerdialogs , timepickerdialogs.

here sections of code:

datepickerdialog

 datepickerdialog datepicker = new datepickerdialog(context, new datepickerdialog.ondatesetlistener() {        @override       public void ondateset(android.widget.datepicker view, int chosenyear, int chosenmonth, int chosendate) {             year = chosenyear;            month = chosenmonth;            date = chosendate;             set(year, month, date);       }  }, year, month, date);   datepicker.settitle("select date");  datepicker.show();

timepickerdialog

 timepickerdialog timepicker = new timepickerdialog(context, new timepickerdialog.ontimesetlistener() {        @override       public void ontimeset(android.widget.timepicker view, int chosenhour, int chosenminute) {            hour = chosenhour;            minute = chosenminute;             set(hour, minute);        }  }, hour, minute, false);   timepicker.settitle("select time");  timepicker.show();
