Min date Max date not working in xamarin android


I'm using the xamarin android datepicker dialog fragment. but tried to enable date between today and toady + 3 days. It's not working. It's not even working for min date options only.

public static readonly string TAG = "X:" + typeof (DatePickerFragment).Name.ToUpper();
        Action<DateTime> _dateSelectedHandler = delegate { };

        public void OnDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
        {
            // Note: monthOfYear is a value between 0 and 11, not 1 and 12!
            DateTime selectedDate = new DateTime(year, monthOfYear +1, dayOfMonth);
            Log.Debug(TAG, selectedDate.ToLongDateString());
            _dateSelectedHandler(selectedDate);
        }

        public static DatePickerFragment NewInstance(Action<DateTime> onDateSelected)
        {
            DatePickerFragment frag = new DatePickerFragment();
            frag._dateSelectedHandler = onDateSelected;
            return frag;
        }

        public override Dialog OnCreateDialog(Bundle savedInstanceState)
        {
            DateTime currently = DateTime.Now;
            DatePickerDialog dialog = new DatePickerDialog(Activity, this, currently.Year, currently.Month - 1,
                                                           currently.Day);

            dialog.DatePicker.MinDate = currently.Millisecond;
            dialog.DatePicker.MinDate = currently.AddDays(3).Millisecond;

            return dialog;
        }

Solution

  • You could change the code of OnCreateDialog.

     public override Dialog OnCreateDialog(Bundle savedInstanceState)
        {
            DateTime currently = DateTime.Now;
            DatePickerDialog dialog = new DatePickerDialog(Activity,
                                                           this,
                                                           currently.Year,
                                                           currently.Month - 1,
                                                           currently.Day);
    
           dialog.DatePicker.MinDate = (long)(DateTime.Now.Date - new DateTime(1970, 1, 1)).TotalMilliseconds-1000 * 60 * 60 * 24 * 3;
           dialog.DatePicker.MaxDate = (long)(DateTime.Now.Date - new DateTime(1970, 1, 1)).TotalMilliseconds + 1000 * 60 * 60 * 24 * 3;
            return dialog;
        }
    

    There is screenshot of DatePicker.Note: i set the minimum date is three days ago, max date is three days later.
