我有一个由这样的SQLite查询的返回值填充的列表
class TableClass
{
public string Name {get;set};
public string id {get;set};
}
List<TableClass> myClass = Database.GetListOfObjects<TableClass>();
返回时，myClass为非null。
由此，我尝试创建一个ListView，这是我遇到绑定问题的地方。目前我的代码看起来像这样
var publist = new ListView
{
ItemsSource = pubgroups,
IsGroupingEnabled = true,
GroupDisplayBinding = new Binding("Public"),
ItemTemplate = new DataTemplate(() =>
{
var label = new Label()
{
Text = SetBinding(TextCell.TextProperty, "Name"),
ClassId = SetBinding(ClassIdProperty, "id")
};
var image = new Image()
{
ClassId = SetBinding(ClassIdProperty, "id"),
Source = Device.OS == TargetPlatform.WinPhone ? "Images/groups" : "groups",
WidthRequest = 50,
HeightRequest = 50,
};
return new ViewCell
{
View = new StackLayout
{
Padding = new Thickness(0, 5),
Orientation = StackOrientation.Horizontal,
Children =
{
image,
new StackLayout
{
VerticalOptions = LayoutOptions.Center,
Spacing = 0,
Children =
{
label
}
}
}
}
};
}),
};
pubgroupstack.Children.Add(publist);
当我尝试构建时，在SetBinding行上出现错误。错误是The best overloaded method match for Xamarin.Forms.BindableObject.SetBinding(Xamarin.Forms.BindableProperty, Xamarin.Forms.BindableBase) has some invalid arguments
有没有一种方法可以根据列表中的属性执行此绑定？
SetBinding返回一个void-将其分配给您的属性不会做任何有用的事情。您还尝试使用TextCell.TextProperty绑定标签，这是错误的。
代替
var label = new Label()
{
Text = SetBinding(TextCell.TextProperty, "Name"),
ClassId = SetBinding(ClassIdProperty, "id")
};
尝试
var label = new Label();
label.SetBinding(Label.TextProperty, "Name");
label.SetBinding(Label.ClassIdProperty, "id");
