请告诉我应该如何将图像 URL 保存到我的 HashMap

我不太懂编码，所以我从 Youtube 视频和博客中获取了内容，但我找不到这个问题

我在 HashMap 处收到错误：

final HashMap<String, Object> cartMap = new HashMap<>();
        cartMap.put("pid", productID);
        cartMap.put("pname", productName.getText().toString());
        cartMap.put("price", productPrice.getText().toString());
        cartMap.put("date", saveCurrentDate);
        cartMap.put("time", saveCurrentTime);
        cartMap.put("quantity", numberButton.getNumber());
        cartMap.put("discount", "");
        cartMap.put("image", productImage);

行：

 cartMap.put("image, productImage);

Answer 1

问题来自这一行：

cartMap.put("image", productImage);

您已将 productImage 声明为：

private ImageView productImage;

并且无法将 ImageView 保存到 Firestore，因为 Firestore 只能包含列出的数据类型 here。您收到的错误是 Firestore 客户端表示它不知道如何处理您传入的类型的方式。

如果您想将图像数据本身存储在 Firestore 中，则必须 and store those. But more common these days is to store the image data itself in Cloud Storage through Firebase，然后将该图像（或其下载 URL）的路径存储在 Firestore 中。
