Getting user name, lastname and ID in Firebase

问题

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.

回答1:

To get a Unique ID, you can use:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
String uid = user.getUid();

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();

For google sign-in you can use:

GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getActivity());
if (acct != null) {
  String personName = acct.getDisplayName();
  String personGivenName = acct.getGivenName();
  String personFamilyName = acct.getFamilyName();
  String personEmail = acct.getEmail();
  String personId = acct.getId();
  Uri personPhoto = acct.getPhotoUrl();
}
