В Xamarin.forms Android вы можете попробовать приведенный ниже код.
Создать класс DateTimePicker.cs.
public class DateTimePicker : Entry, INotifyPropertyChanged
{
public DatePicker _datePicker { get; private set; } = new DatePicker() { MinimumDate = DateTime.Today, IsVisible = false };
public TimePicker _timePicker { get; private set; } = new TimePicker() { IsVisible = false };
string _stringFormat { get; set; }
public string StringFormat { get { return _stringFormat ?? "dd/MM/yyyy HH:mm"; } set { _stringFormat = value; } }
public DateTime DateTime
{
get { return (DateTime)GetValue(DateTimeProperty); }
set { SetValue(DateTimeProperty, value); OnPropertyChanged("DateTime"); }
}
private TimeSpan _time
{
get
{
return TimeSpan.FromTicks(DateTime.Ticks);
}
set
{
DateTime = new DateTime(DateTime.Date.Ticks).AddTicks(value.Ticks);
}
}
private DateTime _date
{
get
{
return DateTime.Date;
}
set
{
DateTime = new DateTime(DateTime.TimeOfDay.Ticks).AddTicks(value.Ticks);
}
}
BindableProperty DateTimeProperty = BindableProperty.Create("DateTime", typeof(DateTime), typeof(DateTimePicker), DateTime.Now, BindingMode.TwoWay, propertyChanged: DTPropertyChanged);
public DateTimePicker()
{
BindingContext = this;
_datePicker.SetBinding<DateTimePicker>(DatePicker.DateProperty, p => p._date);
_timePicker.SetBinding<DateTimePicker>(TimePicker.TimeProperty, p => p._time);
_timePicker.Unfocused += (sender, args) => _time = _timePicker.Time;
_datePicker.Focused += (s, a) => UpdateEntryText();
GestureRecognizers.Add(new TapGestureRecognizer()
{
Command = new Command(() => _datePicker.Focus())
});
Focused += (sender, args) =>
{
Device.BeginInvokeOnMainThread(() => _datePicker.Focus());
};
_datePicker.Unfocused += (sender, args) =>
{
Device.BeginInvokeOnMainThread(() =>
{
_timePicker.Focus();
_date = _datePicker.Date;
UpdateEntryText();
});
};
}
private void UpdateEntryText()
{
Text = DateTime.ToString(StringFormat);
}
static void DTPropertyChanged(BindableObject bindable, object oldValue, object newValue)
{
var timePicker = (bindable as DateTimePicker);
timePicker.UpdateEntryText();
}
}
Использование в App.xaml.cs
var dtPicker = new DateTimePicker()
{
VerticalOptions = LayoutOptions.FillAndExpand,
HorizontalOptions = LayoutOptions.FillAndExpand,
StringFormat = "HH:mm dd/MM/yyyy"
};
MainPage = new ContentPage
{
Content = new StackLayout
{
VerticalOptions = LayoutOptions.Center,
Children = {
dtPicker._datePicker,
dtPicker._timePicker,
dtPicker
},
BackgroundColor = Color.Aqua
}
};
