DatePicker View Tutorial

The DatePicker view, enables users to select a particular date on the activity. 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.

You can create DatePicker View using <DatePicker> xml element like this -

DatePicker view has three main methods-

getMonth()
getDayOfMonth()
getYear()

These methods are used to get month , day & year respectively. Please note that the getMonth() method returns 0 (zero) for January, 1 for February & so on. Hence, you need to add a one to the result of this method to get the month number.
