Create a Calender instance and set the date you want. Then call calendar.getTimeInMillis();. See the answer of this previous SO question for more information.

EDIT To set the calendar date you can use something like this:

//Lets suppose you have a DatePicker instance called datePicker
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, datePicker.getDayOfMonth());
cal.set(Calendar.MONTH, datePicker.getMonth());
cal.set(Calendar.YEAR, datePicker.getYear());

See the Calendar class for more information.
