Question

我在Android上使用Firebase来注册用户并将其数据插入到数据库中。我有3个类，片段类从用户获取所有数据 - ＆gt;将对象发送到Model类 - ＆gt; UserModelFirebase

这是项目的层次结构。

这是代码：

SignUpFragment

    public void SignUp(){
        User newUser = new User(txtEmail.getText().toString(),
            txtPassword.getText().toString(),
            false);

    String password = txtPassword.getText().toString();

    Model.instance.addUser(newUser, password, new Model.IAddUser() {
        @Override
        public void onComplete(User user) {
            MusicPostListFragment listFragment = MusicPostListFragment.newInstance(1);
            onButtonPressed(listFragment);
        }

        @Override
        public void onError(String reason) {
            Toast.makeText(v.getContext(), "Unable to create user, Please try again", Toast.LENGTH_LONG);
        }
    });
}

模型

public class Model {
private ModelUserFirebase modelUserFirebase;
public final static Model instance = new Model();

private Model(){
    modelUserFirebase = new ModelUserFirebase();
       }

public interface IAddUser {
    void onComplete(User user);
    void onError(String reason);
}
public void addUser(User user, String password, final IAddUser callback ) {
    modelUserFirebase.addUser(user, password, new ModelUserFirebase.IAddUser() {
        @Override
        public void onComplete(User user) {
            callback.onComplete(user);
        }

        @Override
        public void onError(String reason) {
            callback.onError(reason);
        }
    });
}

UserModelFirebase

public class ModelUserFirebase {

private static final String USERS_KEY = "Users";
private FirebaseAuth firebaseAuth;
private FirebaseDatabase database;
private DatabaseReference usersReference;
private FirebaseAuth.AuthStateListener mAuthStateListener;

private User currentUser;

public ModelUserFirebase() {
    firebaseAuth = FirebaseAuth.getInstance();
    database = FirebaseDatabase.getInstance();
    usersReference = database.getReference(USERS_KEY);
}

interface IAddUser {
    void onComplete(User user);
    void onError(String reason);
}
public void addUser(final User user, String password, final IAddUser callback) {
    firebaseAuth.createUserWithEmailAndPassword(user.getEmail(), "123456Ee!")
            .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    Log.d("dev","createUserWithEmail: onComplete()");
                    FirebaseUser firebaseUser = task.isSuccessful() ?
                            firebaseAuth.getCurrentUser() : null;

                    if (firebaseUser != null) {
                        User savedUser = new User(user);
                        savedUser.setId(firebaseUser.getUid());
                        usersReference.child(firebaseUser.getUid()).setValue(savedUser);
                        callback.onComplete(savedUser);
                    }
                    else {
                        callback.onError(task.getException().getMessage());
                    }
                }
            });
}

发生了什么事？当我调试代码时，我看到addOnCompleteListener行之后什么都没发生，也没有onComplete onError

Firebase身份验证，函数createUserWithEmailAndPassword dosent执行
