You can use “
android.widget.DatePicker”
class to render a date picker component to select day, month and year
in a pre-defined user interface in android
In this tutorial, you'll create a
DatePickerDialog,
which presents the date picker in a floating dialog box at the press
of a button. When the date is set by the user, a
TextView
will update with the new date.
