DatePicker and Timepicker monitoring events get the user select Year Month day seconds/minute information

public class Mainactivity extends Appcompatactivity {private Timepicker timepicker;    Private DatePicker DatePicker;    Private Calendar cal;    private int year;    private int month;    private int day;    private int hour;    private int minute;        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main);        Registered Object Timepicker = (timepicker) Findviewbyid (R.id.timepicker);        DatePicker = (datePicker) Findviewbyid (R.id.datepicker);        Gets the month day seconds information cal = Calendar.getinstance ();        Year = Cal.get (calendar.year);        month = Cal.get (calendar.month); Day = Cal.get (calendar.day_of_month) + 1;        The month starts from 0 so add 1 hour = Cal.get (Calendar.hour_of_day);        minute = Cal.get (Calendar.minute);        Title Display Settitle (year + "-" + month + "-" + Day + "-" + Hour + ":" + minute);        DatePicker initialization Set Initial dateDatepicker.init (year, Cal.get (Calendar.month), Day, new Datepicker.ondatechangedlistener () {@Override public void ondatechanged (DatePicker view, int year, int monthofyear, int. dayofmonth) {Settitle (year +            "-" + (Monthofyear + 1) + "-" + dayofmonth);    }        }); }

Timepicker Monitoring Event Example

        Timepicker.setontimechangedlistener (New Timepicker.ontimechangedlistener () {            @Override public            Void Ontimechanged (timepicker view, int hourofday, int minute) {                                settitle (hourofday + ":" + minute);            }        );

Simultaneous monitoring of the date and time can be an alarm clock

public class Mainactivity extends Appcompatactivity {private Timepicker timepicker;    Private DatePicker DatePicker;    Private Calendar cal;    private int year;    private int month;    private int day;    private int hour;    private int Minute;        @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main);        Registered Object Timepicker = (timepicker) Findviewbyid (R.id.timepicker);        DatePicker = (datePicker) Findviewbyid (R.id.datepicker);        Gets the month day seconds information cal = Calendar.getinstance ();        Year = Cal.get (calendar.year);     month = Cal.get (calendar.month) + 1;        The month starts from 0 so add 1 day = Cal.get (calendar.day_of_month);        hour = Cal.get (Calendar.hour_of_day);        Minute = Cal.get (Calendar.minute);        Title Display Settitle (year + "-" + month + "-" + Day + "-" + Hour + ":" + Minute);  DatePicker initialization Set Initial date      Datepicker.init (year, Cal.get (Calendar.month), Day, new Datepicker.ondatechangedlistener () {@Override public void ondatechanged (DatePicker view, int year, int monthofyear, int dayofmonth) {month = mo                Nthofyear + 1;                Day = DayOfMonth;                Year = year;            Settitle (Year + "-" + month + "-" + Day + "-" + Hour + ":" + Minute);        }        }); Timepicker.setontimechangedlistener (New Timepicker.ontimechangedlistener () {@Override public void O                Ntimechanged (timepicker view, int hourofday, int minute) {hour = Hourofday;                Minute = Minute;            Settitle (Year + "-" + month + "-" + Day + "-" + Hour + ":" + Minute);    }        }); }
