好吧,我是Xamarin的新手,对此有点挣扎。我正在尝试创建带有“页面”或“卡片”轮播的页面。它实际上可以正常工作,但是我无法在其中发布动态数据(名称,schoolClass和课程)?
这就是我想要做的:
ObservableCollection<Details> collection = new ObservableCollection<Details>();
collection.Add(new Details { name = "Peter Hanson", schoolClass = "4. klasse", course = "Math" });
collection.Add(new Details { name = "Tom Jerk", schoolClass = "7. klasse", course = "Geography" });
collection.Add(new Details { name = "Caroline Jump", schoolClass = "1. klasse", course = "English" });
// Carousel pages template
DataTemplate template = new DataTemplate(() =>
{
var stacksample = new StackLayout()
{
HorizontalOptions = LayoutOptions.FillAndExpand,
VerticalOptions = LayoutOptions.FillAndExpand,
BackgroundColor = Color.White
};
stacksample.Children.Add(new Label
{
Text = "{Binding name}",
HorizontalOptions = LayoutOptions.Center
});
stacksample.Children.Add(new Image
{
Source = ImageSource.FromResource("md.Images.default.png",
typeof(EmbeddedImage).GetTypeInfo().Assembly)
});
stacksample.Children.Add(new Label
{
Text = "{Binding schoolClass}",
HorizontalOptions = LayoutOptions.Center,
Style = Headline
});
stacksample.Children.Add(new Label
{
Text = "{Binding course}",
HorizontalOptions = LayoutOptions.Center,
Margin = new Thickness(0, -8, 0, 0),
Style = SubStyle
});
return stacksample;
});
carousel.ItemTemplate = template;
carousel.PositionSelected += pageChanged;
carousel.ItemsSource = collection;
我希望有人能在正确的方向上帮助或指导我,并预先致谢:-)
