Firebase UserProfileChangeRequest无法正常工作 [英] Firebase UserProfileChangeRequest isn't working

问题描述

我正在尝试创建个人资料活动，用户可以在其中更改那些个人资料"图片和显示名称，我正在尝试更新用户照片或用户名，CompleteListener称为task.isSuccessful = true，但是什么都做完了，为什么?

I'm trying to create an profile activity, where users can change those Profile picture and Display name, I'm trying to update user photo or user name, CompleteListener called, task.isSuccessful = true but nathing done, why?

用于更新名称的功能:

FirebaseUser mFirebaseUser = FirebaseAuth.getInstance().getCurrentUser();
final String newName;
newName = input.getText().toString();
UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
.setDisplayName(newName)
.build();
mFirebaseUser.updateProfile(profileUpdates)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
DatabaseReference mFirebaseDatabaseReference = FirebaseDatabase.getInstance().getReference().child("users");
   mFirebaseDatabaseReference.child(mFirebaseUser.getUid()).child("DisplayName").setValue(newName);
updateUI();
Toast.makeText(ProfileActivity.this, "User display name updated.", Toast.LENGTH_SHORT).show();
} else
Toast.makeText(ProfileActivity.this, "Error while updating display name.", Toast.LENGTH_SHORT).show();
}
});

与我尝试更新刚刚上传到Firebase存储的个人资料图片相同...

Same when i'm trying to update Profile picture that I just uploaded to Firebase Storage...

有主意吗?

有时用户名确实会更新，我认为更新大约需要10分钟以上，为什么?

Sometimes the username really get updated, I think it's take like more then 10 minutes to update, why?

推荐答案

我遇到了一个类似的问题，即直到用户重新验证后，用户信息才更新.我也通过将这些信息保存在我的Firebase数据库中来解决此问题.对我来说，这很有意义，因为我希望用户无论如何都能获得有关其他用户的基本信息.

I have had a similar problem where the User information was not updating until the User re-authenticated. I resolved it by also saving this information in my firebase database. For me this made sense, as I wanted Users to be able to get basic information about other Users anyway.

我的代码最终看起来像这样.创建或修改帐户后，我调用了"users/{uid}"端点，并在那里更新了对象.在这里，我使用 GreenRobot EventBus 将我的新User对象发送给订阅的任何人，以便在屏幕上更新.

My code ended up looking something like this. When the account is created, or modified, I made a call to the "users/{uid}" endpoint and updated the object there. From here I used the GreenRobot EventBus to send my new User object to whoever was subscribed so that it would be updated on the screen.

private FirebaseUser firebaseUser;

public void createUser(String email, String password, final User user, Activity activity, final View view) {
    FirebaseAuth.getInstance().createUserWithEmailAndPassword(email, password)
        .addOnCompleteListener(activity, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());

                // If sign in fails, display a messsage to the user. If sign in successful
                // the auth state listener will be notified and logic to handle
                // signed in user can be handled in the listener
                if (!task.isSuccessful()) {
                    Snackbar.make(view, task.getException().getLocalizedMessage(), Snackbar.LENGTH_SHORT).show();
                } else {
                    firebaseUser = task.getResult().getUser();

                    UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                        .setDisplayName(user.displayName)
                        .build();
                    firebaseUser.updateProfile(profileUpdates);
                    updateDatabase(user);

                    EventBus.getDefault().post(new LoginEvent());
                }
            }
        });
}

public boolean updateDatabase(User user) {
    if (firebaseUser == null) {
        Log.e(TAG, "updateDatabase:no currentUser");
        return false;
    }

    return userReference.setValue(user).isSuccessful();
}

数据库监视程序的设置是这样完成的.请注意，您需要确保在用户注销时删除监听器，并在用户登录时添加新监听器.

The setup of the database watcher was done something like this. Note that you need to make sure that you remove the listener when the User logs out and add a new one when the User logs in.

protected void setupDatabaseWatcher() {
    String uid = firebaseUser.getUid();

    userReference = FirebaseDatabase.getInstance().getReference("users/" + uid);
    userReference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            // This method is called once with the initial value and again
            // whenever data at this location is updated.
            User user = dataSnapshot.getValue(User.class);
            Log.d(TAG, "Value is: " + user);

            EventBus.getDefault().post(new UserUpdateEvent(user));
        }

        @Override
        public void onCancelled(DatabaseError error) {
            // Failed to read value
            Log.w(TAG, "Failed to read value.", error.toException());
        }
    });
}
