请告诉我应该如何在我的 HashMap 中保存图像 URL

我不太懂编码，所以我从 Youtube 视频和博客中获取内容，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);

在线：

 cartMap.put("image, productImage);

Answer 1

问题出在这一行：

cartMap.put("image", productImage);

您已将productImage 声明为：

private ImageView productImage;

而且无法将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。

---

如果您想将图像数据本身存储在 Firestore 中，则必须 get the bytes from the image view 并存储这些数据。但现在更常见的是store the image data itself in Cloud Storage through Firebase，然后将该图像的路径（或其下载 URL）存储在 Firestore 中。
