【问题描述】：
我在这一行有一个错误：final User user = new User(Address, confirmPassword, UserEmail, Password, PhoneNumber, Username,link);
错误是“无法解决符号链接”

如果您需要更多详细信息，请在下面发表评论，我已经删除了一些代码。任何人都可以帮助解决这个问题吗？非常感谢您的帮助
【问题讨论】：
-
您的
link对象是字符串类型的有效对象。能否请添加您的错误的屏幕截图，看看它的样子？ -
我添加了一张图片，这是您要求的吗？
-
你从不声明链接
-
我声明了 String link = downloadUri.toString();在添加成功监听器
