在Firebase中获取用户名，姓氏和ID
问题描述：
我使用firebase创建了一个登录/注册，并且工作正常.但是我需要从用户那里获取姓名和姓氏.我怎样才能做到这一点?我想知道是否有可能从用户那里获得ID，因为我想在我的应用中创建一个排名页面，因此只有ID是唯一的.
I created a login/register using firebase, and it's working fine. But I need to get name and lastname from the user. How can I do this? And I'd like to know if it's possible to get an ID from the user, because I want to create a Rank Page in my app, so only an ID would be unique to do this.
答
要获取唯一ID，您可以使用:
To get a Unique ID, you can use:
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
String uid = user.getUid();
要获取他的名字(我从未在Email/password auth中尝试过此操作，但在第三方提供者auth上可以正常使用):
To get his name (I never tried this in Email/password auth, but it works fine on 3rd party providers auth):
String name = user.getDisplayName();
