Can I get milliseconds date value from a datepicker? (the milliseconds since 1970 value)

I have a DatePicker d; and I need to get the开发者_开发百科 milliseconds value of the date. (the milliseconds since 1970 value)

how can I do it?

Create a calender object and set the date and time from the date picker and today.getTimeInMillis().

onDateSet(...) {
    Calendar c = Calendar.getInstance();
    c.set(...);
    long mills = c.getTimeInMillis();
}

You just have to convert your result, using Calendar, or, more easily, Joda-Time

Here is an example with Joda-Time :

DateMidnight d = new DateMidnight(picker.getYear(), picker.getMonth(), picker.getDayOfMonth());
long millis = d.toDate().getTime();
