Xaml在设置Listview后分配额外的类

Question

以下是模型:https://github.com/xiaofaye/woocommerce.net/blob/master/woocommerce/v3/product.cs#L503

当生成列表时，我将迭代产品类。但是，图像存储在不同的模型中，我不知道如何在listview已经设置好之后调用Xaml的另一个类。

我只需要一个图像来传递我知道产品模型有一个列表称为图像，但我不知道如何将列表传递到图像源绑定

后端

 public Products()
        {
            InitializeComponent();



            InitAsync();



        }
        private async void Back_Clicked(object sender, EventArgs e)
        {
            await Navigation.PopAsync();
        }



        private async Task InitAsync()
        {



            RestAPI rest = new RestAPI("http://example.co.za/wp-json/wc/v3/", "CK_XXXXXX", "cs_xXXXXX");
                WCObject wc = new WCObject(rest);
            var products = await wc.Product.GetAll();
            var p = await wc.Product.GetAll(new Dictionary<string, string>() {
                    {"tag", Suppliers.tagid },
                    { "per_page", "80" } }); ;

            List<ProductImage> z = new List<string> { p.images };
            productsListView.ItemsSource = p;

        }

        async void ProductClicked(object sender, EventArgs args)
        {





            var btn = (Button)sender;

           var a = btn.BindingContext;

            Orders.singleID = Convert.ToInt32(a);




           await Navigation.PushAsync(new Orders());

Answer 1

我没有办法做到这一点，确切的事情我当时想要的。

简而言之，问题是产品有一个Image[]作为示例，我需要访问

Product image[].src所以在绑定中，我最后说

  var p = await wc.Product.GetAll(new Dictionary<string, string>() {
                    {"tag", Suppliers.tagid },
                    { "per_page", "80" } }); ;



  foreach (var item in p)
            {
                foreach (var z in item.images)
                {
                    if (item.images != null)
                    {
                        var YourBinding = z.src;
                    }
                }
            }
