Android UI Control Series: Datepicker,timepicker (date and time selection)

The date and time are the features of any mobile platform, and so does Android.

DatePicker: Used to implement the date (Year month day)

Timepicker: Used to implement time (hours, minutes, seconds)
Calendar: An abstract base class that converts between an annual date object and an integer number field, such as month, day, hour, and so on.

For example

Final Calendar calendar=calendar.getinstance (); Myear=calendar.get (calendar.year);-Get year mmonth=calendar.get ( Calendar.month);-Get the Month mday=calendar.get (calendar.day_of_month);-Get the Day Mhour=calendar.get (calendar.hour_of_day);- Get Mminute=calendar.get (Calendar.minute);-Get points

And so on, you can refer to the API documentation

Timepickerdialog, Datepickerdialog is the time class in the form of dialog boxes.

Needless to say, the example is as follows:
