How do I set the current date in a DatePicker?

I need to be able to choose date and time in my application It should either be done by using a dialog, or starting a new intent.

The way I have done it now, is that I have started a new intent, since I need to set both date a开发者_如何学Gond time.

My problem is that I need to set the current date on the Datepicker (This is possible with the Timepicker using setCurrentHour and setCurrentMinute) onCreate, and set that as a lower boundary.

I can't find any functions in the Android API for doing this with the DatePicker.

Anyone have a suggestion to solve this problem?

Thanks in advance!

Edit: Important: The DatePicker and TimePicker must be in the same dialog/intent

Straight to code

Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR);
int mMonth = c.get(Calendar.MONTH);
int mDay = c.get(Calendar.DAY_OF_MONTH);

DatePickerDialog dialog =
    new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
dialog.show();

---

Try this:

Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);     

// set current date into datepicker
datepicker.init(year, month, day, null);

If you are simply looking for the equivalent of setCurrentHour() and setCurrentMinute() on TimePicker, but on DatePicker - see updateDate (int year, int month, int dayOfMonth) on DatePicker.

DatePicker mDatePicker = (DatePicker) findViewById(R.id.datePicker);
mDatePicker.updateDate(1994, 6, 12);
// Sets date displayed on DatePicker to 12th June 1994

You can query the current date through the Calendar class.

Calendar now = Calendar.getInstance();
now.get(Calendar.WHATDOYOUNEED);

Feed it's get() method with different parameters to customize your query.

The tutorial for the DatePicker seems to do exactly this?

http://developer.android.com/resources/tutorials/views/hello-datepicker.html

Refer to:

    // get the current date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    // display the current date (this method is below)
    updateDisplay();
