java - Firebase 登录 - 加载卡住

Question

我的问题是，完成注册或注册表单后 - 用户在我的 Firebase 中正确显示 - 但加载不断转动并且不转到下一页。

表单如下:LoginActivity.java，然后menuPrincipal.java

-或-、profileRegistration.java、profileRegistration.java，然后 menuPrincipal.java。

代码中没有显示错误。唯一奇怪的事情是在 profileRegistration.java 中:

public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        progressBarImage.setVisibility(View.GONE);
                        profileImageUrl =   taskSnapshot.getDownloadUrl().toString();
                    }

.getDownloadUrl() 被划线，它表示它已被弃用，但没有出现任何错误。

这是我的LoginActivity.java:

    }

    //Ceci est la condition du mot de passe qui doit être de plus de 6 caractères
    if (password.length()<6) {
        passwordLogin.setError("Minimum length of password is 6.");
        passwordLogin.requestFocus();
        return;
    }

    //Ceci est pour le gif loading pendant la création du compte
    progressBar.setVisibility(View.VISIBLE);

    //Ceci permet de passer au Menu Principal une fois que le login est successful
    mAuth.signInWithEmailAndPassword(email, password)
            .addOnCompleteListener(LoginActivity.this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    // If sign in fails, display a message to the user. If sign in succeeds
                    // the auth state listener will be notified and logic to handle the
                     // signed in user can be handled in the listener.
                    progressBar.setVisibility(View.GONE);
                    if (!task.isSuccessful()) {

                    }
                      else{
                        Intent intent = new Intent(LoginActivity.this, menuPrincipal.class);

                    }
                }

我对此还很陌生，所以如果问题确实很明显而我没有看到它，我很抱歉。预先感谢您!

您的寄存器应该是:

auth.createUserWithEmailAndPassword(email, password)
                        .addOnCompleteListener(RegistrationActivity.this, new OnCompleteListener<AuthResult>() {
                            @Override
                            public void onComplete(@NonNull Task<AuthResult> task) {
                                Toast.makeText(SignupActivity.this, "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show();
                                progressBar.setVisibility(View.GONE);

在您的profileRegistration中，您应该调用LoginActivity

@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressBarImage.setVisibility(View.GONE);
profileImageUrl = taskSnapshot.getDownloadUrl().toString();
}

您需要添加

Intent intent = new Intent(profileRegistration.this,  LoginActivity.class);
                            startActivity(intent); 

在LoginActivity中应该是

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //Get Firebase auth instance
        auth = FirebaseAuth.getInstance();

        if (auth.getCurrentUser() != null) {
            startActivity(new Intent(LoginActivity.this, MainActivity.class));
            finish();
        }

        // set the view now
        setContentView(R.layout.activity_login);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        inputEmail = (EditText) findViewById(R.id.emailLogin);
        inputPassword = (EditText) findViewById(R.id.passwordLogin);
        progressBar = (ProgressBar) findViewById(R.id.progressBar);
        btnSignup = (Button) findViewById(R.id.signUp);
        btnLogin = (Button) findViewById(R.id.logNow);

        //Get Firebase auth instance
        auth = FirebaseAuth.getInstance();

        btnSignup.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(LoginActivity.this, RegistrationActivity.class));
            }
        });

        btnReset.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(LoginActivity.this, ResetPasswordActivity.class));
            }
        });

        btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String email = inputEmail.getText().toString();
                final String password = inputPassword.getText().toString();

                if (TextUtils.isEmpty(email)) {
                    Toast.makeText(getApplicationContext(), "Enter email address!", Toast.LENGTH_SHORT).show();
                    return;
                }

                if (TextUtils.isEmpty(password)) {
                    Toast.makeText(getApplicationContext(), "Enter password!", Toast.LENGTH_SHORT).show();
                    return;
                }

                progressBar.setVisibility(View.VISIBLE);

                //authenticate user
                auth.signInWithEmailAndPassword(email, password)
                        .addOnCompleteListener(LoginActivity.this, new OnCompleteListener<AuthResult>() {

                                    if (password.length() < 6) {
                                        inputPassword.setError(getString(R.string.minimum_password));
                                    } else {
                                        Toast.makeText(LoginActivity.this, getString(R.string.auth_failed), Toast.LENGTH_LONG).show();
                                    }
                                } else {
