Question

我正在将Prism与Xamarin Forms一起使用，并将所有软件包都保持最新。我在项目中使用SfRotator，SfNavigationDrawer等，但是我的问题是SfRotator。旋转器中的图像未显示。我尝试使用未显示任何图像的控件。我移到FFImageLoading，它在SfRotator外部起作用，但在内部不起作用。另外，如果我在或内使用CachedImageFastRenderer，则会引发NullReferenceException

以下是代码段：

MainPageViewModel.cs

 public class MainPageViewModel : ViewModelBase

    private List imageCollection;
    public List ImageCollection

    set { SetProperty(ref imageCollection, value); }

    public MainPageViewModel(INavigationService navigationService)
    : base(navigationService)
    {
    Title = "Main Page";

    ImageCollection = new List();
    ImageCollection.Add(new OfferSection ("offer1.jpg", "1" ));
    ImageCollection.Add(new OfferSection ("offer2.jpg", "2" ));
    ImageCollection.Add(new OfferSection ("offer3.png", "3" ));
    }

OfferSection.cs

public class OfferSection
{

public string Image { get; set; }

public string OfferId { get; set; }

public OfferSection(string image, string id )
{
Image = image;
OfferId = id;
}

先谢谢了。等待迅速的响应

我们确认我们能够重现“ 图像未在android的旋转器中显示”的问题。我们已经记录了此问题的错误报告，并将在2018年第4卷SP1中提供此修复程序，预计将在 2019年2月的第一个星期推出。

注意：我为Syncfusion工作。
