android - 保存后个人资料图片不显示(它只显示空白屏幕)

Question

我正在尝试上传用户个人资料图片并存储在 firebase 中。我的图片已成功存储在 firebase 存储和用户数据库中。

当我上传图像时它显示在我的屏幕上，但是一旦我保存并重新打开设置以查看个人资料图像，它就没有显示，它只显示空白屏幕(但名称和电话在重新打开时显示，仅图片不显示)

我附上了从 db 获取值并在 ui 中显示的代码，还添加了当用户单击保存图像按钮时调用的 saveUserInformation()，此函数将名称、电话和个人资料图像保存在 db 中。我在下面添加了数据库的屏幕截图，还添加了我收到的错误 fragment 。

我做错了什么？

这是我控制台记录时 glide 输出的内容:在此处配置文件 img:目标:android.support.v7.widget.AppCompatImageView{528bbb2 V.ED..C.. ......ID 0,0-300,300 #7f0a00b9 app:id/profileImage}[CDS]rx超时:0

您收到以下错误:

Load failed for com.google.android.gms.tasks.zzu@c0645c1

因为你试图显示一个不存在的图像。正如我在您的数据库中看到的那样，profileImageUrl 属性包含一个无效有效的图像 url。

看到红线了吗？它实际保存的是内存中对象的地址，不是图像 url。发生这种情况是因为您在 downloadUrl 对象上调用 toString() 方法。所以你获取 donwload url 的方式是不正确的。 <强> This 是获取 url 的正确方法。一旦获得图像的 url 并将其添加到数据库，一切都会按预期工作。
