我试图在活动中显示用户的个人资料。但是，当我尝试执行此操作时，它仅显示电子邮件。名称，照片，电话号码未显示。
如何显示当前用户的所有字段？我尝试了
getCurrentuser()
获取当前用户信息并在字段中进行设置。但这并没有显示所有字段。

Android Studio显示
sendEmailVerification()
可能会产生NullPointerException。除了
getReference()
和
getDownloadUrl()
也可能产生NullPOinterException。如何解决所有问题并正确获得预期的输出？ Here is a screenshot of profile.
答案 0 :(得分：0)
您实际上并没有定义用户名， 在Firebase身份验证
的onCompleteListener方法中使用此方法
new UserProfileChangeRequest.Builder()
.setDisplayName(nameUser)
.build();
