Вы должны настроить управление для этого. Пожалуйста, пройдите через это и дайте мне знать, если какой-либо запрос.
1) Расширьте представление прокрутки с помощью пользовательского шаблона.
public class HorizontalListview : ScrollView
{
public static readonly BindableProperty ItemsSourceProperty =
BindableProperty.Create("ItemsSource", typeof(IEnumerable), typeof(HorizontalListview), default(IEnumerable));
public IEnumerable ItemsSource
{
get { return (IEnumerable)GetValue(ItemsSourceProperty); }
set { SetValue(ItemsSourceProperty, value); }
}
public static readonly BindableProperty ItemTemplateProperty =
BindableProperty.Create("ItemTemplate", typeof(DataTemplate), typeof(HorizontalListview), default(DataTemplate));
public DataTemplate ItemTemplate
{
get { return (DataTemplate)GetValue(ItemTemplateProperty); }
set { SetValue(ItemTemplateProperty, value); }
}
public event EventHandler<ItemTappedEventArgs> ItemSelected;
public static readonly BindableProperty SelectedCommandProperty =
BindableProperty.Create("SelectedCommand", typeof(ICommand), typeof(HorizontalListview), null);
public ICommand SelectedCommand
{
get { return (ICommand)GetValue(SelectedCommandProperty); }
set { SetValue(SelectedCommandProperty, value); }
}
public static readonly BindableProperty SelectedCommandParameterProperty =
BindableProperty.Create("SelectedCommandParameter", typeof(object), typeof(HorizontalListview), null);
public object SelectedCommandParameter
{
get { return GetValue(SelectedCommandParameterProperty); }
set { SetValue(SelectedCommandParameterProperty, value); }
}
public void Render()
{
if (ItemTemplate == null || ItemsSource == null)
return;
var layout = new StackLayout();
layout.Spacing = 0;
layout.Orientation = Orientation == ScrollOrientation.Vertical ? StackOrientation.Vertical : StackOrientation.Horizontal;
foreach (var item in ItemsSource)
{
var command = SelectedCommand ?? new Command((obj) =>
{
var args = new ItemTappedEventArgs(ItemsSource, item);
ItemSelected?.Invoke(this, args);
});
var commandParameter = SelectedCommandParameter ?? item;
var viewCell = ItemTemplate.CreateContent() as ViewCell;
viewCell.View.BindingContext = item;
viewCell.View.GestureRecognizers.Add(new TapGestureRecognizer
{
Command = command,
CommandParameter = commandParameter,
NumberOfTapsRequired = 1
});
layout.Children.Add(viewCell.View);
}
Content = layout;
}
}
2) Добавьте верхнюю часть пространства имен на свою страницу.
xmlns:control="clr-namespace:**Projectname**.CustomControls"
3) Использовать контроль,
<control:HorizontalListview Orientation="Horizontal">
<control:HorizontalListview.ItemTemplate>
<DataTemplate>
<ViewCell>
<!....Your Design.....>
</ViewCell>
</DataTemplate>
</control:HorizontalListview.ItemTemplate>
</control:HorizontalListview>
4) Свяжите свои данные.
**YourControlName**.ItemsSource = lLstPhotoGallery; // Your List
**YourControlName**.Render();
