Xamarin.forms ListView 项目不可见

Xamarin.forms ListView Items not visible

我在我的 Droid 项目上将 xamarin.forms 从 v2.0.1.6505 更新到 v2.3.3.180, 我有以下 ListView(简单的):

  customersListView = new ListView() {
                ItemsSource = customers,
                ItemTemplate = new DataTemplate(typeof(EntityViewCell)),
                HorizontalOptions = LayoutOptions.FillAndExpand,
                VerticalOptions = LayoutOptions.FillAndExpand,   
                SeparatorColor = Color.Teal            
            };
  public class EntityViewCell : ImageCell
  {
    public EntityViewCell() : base()
    {
        SetBinding(TextProperty, new Binding("Name"));
        SetBinding(DetailProperty, new Binding("Description"));
        SetBinding(ImageSourceProperty, new Binding("ImageUrl"));
        TextColor = Color.Blue;        
    }
}

我得到以下列表(项目不可见)

为什么我更新后出现问题 Xamarin.forms?

修复解决方案: 尝试

public EntityViewCell() : base()
        {
            SetBinding(TextProperty, new Binding("Name"));
            SetBinding(DetailProperty, new Binding("Description"));
            SetBinding(ImageSourceProperty, new Binding("ImageUrl"));
            TextColor = Color.Blue;//or any other color         
        }
