How to disable past dates in Android date picker?

Question

How can I disable past dates in my Android date picker?

Here's the code that produces my DatePicker:

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        // set date picker as current date
        return new DatePickerDialog(this, datePickerListener, year, month,
                day);
    }
    return null;
}

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int selectedYear,
            int selectedMonth, int selectedDay) {
        year = selectedYear;
        month = selectedMonth+1;
        day = selectedDay;

        startdate.setText(new StringBuilder().append(day).append("-")
                .append(getMonth(month + 1)).append("-").append(year)
                .append(" "));
    }
};

You can do

datePicker.setMinDate(System.currentTimeMillis() - 1000);

which sets today's date as minimum date and all the past dates are disabled.

datePicker is an object of DatePicker if you are using an object of DatePickerDialog you can do

datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);

Note: setMinDate was introduced in API 11
