如何检索用户个人资料名称信息，例如姓名和电子邮件以及个人资料照片？

Question

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {

                        String currentUserID = mAuth.getCurrentUser().getUid();
                        DataRef.child("Users").child(currentUserID).child("Name").setValue(name);
                        DataRef.child("Users").child(currentUserID).child("Email").setValue(email);

                        // Sign in success, update UI with the signed-in user's information
                        Log.d(TAG, "signInWithCredential:success");
                        FirebaseUser user = mAuth.getCurrentUser();
                        updateUI();
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w(TAG, "signInWithCredential:failure", task.getException());
                        // Toast.makeText(MainActivity.this, task.getException().getLocalizedMessage(), Toast.LENGTH_SHORT).show();
                    }

                    // ...
                }
            });

用户信息类：

public class UserInformation {

    private String email;
    private String name;

    public UserInformation(){

    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Answer 1

首先分配 Firebase 用户。

FirebaseUser firebaseUser = mAuth.getCurrentUser();

将保存用户的数据。

检索当前用户数据有不同的方法

String userEmail = firebaseUser.getEmail();
String uid = firebaseUser.getDisplayName();
String photouri = String.ValueOf(firebaseUser.getPhotoUrl());

Answer 2

在task.isSuccessful(){你需要添加：

user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null) {
    String uid = user.getUid();
    token = user.getUid();
    email = user.getEmail();
    displayName = user.getDisplayName();
}
