如何禁用过去的日期并限制用户选择通过时间

Question

如何设置日期和时间选择器的MinDate 和时间。我尝试将其设置为日期，但它不起作用。我不确定如何为 Time 设置它。

private DatePickerDialog showDatePicker() {

    int todaysDate = mCalendar.get(Calendar.DATE);
    datePicker = new DatePickerDialog(ReminderEditActivity.this, new DatePickerDialog.OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

            mCalendar.set(Calendar.YEAR, year);

            mCalendar.set(Calendar.MONTH, monthOfYear);
            mCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
            //view.setMinDate(System.currentTimeMillis() - 1000);
            datePicker.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
            updateDateButtonText(); 
        }

    }, mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH)); 

    return datePicker; 
}

private TimePickerDialog showTimePicker() {

    TimePickerDialog timePicker = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            mCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
            mCalendar.set(Calendar.MINUTE, minute); 
            updateTimeButtonText(); 
        }
    }, mCalendar.get(Calendar.HOUR_OF_DAY), mCalendar.get(Calendar.MINUTE), true); 

    return timePicker; 
}

你可以像这样设置 minDate(type long)

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