我正在使用 xamarin android datepicker 对话框 fragment 。但试图启用今天和 toady + 3 天之间的日期。它不工作。它甚至不适用于最小日期选项。
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;
}
最佳答案
您可以更改 OnCreateDialog
的代码。
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;
}
有DatePicker的截图。注意:我设置的最小日期是三天前,最大日期是三天后。
关于android - 最小日期最大日期在 xamarin android 中不起作用,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/54353741/
