Firebase用户登录失败，找不到无效的电子邮件com.google.firebase.auth

Question

我的LoginActivity包含EditText，用户可以输入他们的电子邮件和密码。所有代码对我来说都没问题。

但是，单击登录按钮后，用户无法登录。事实证明，该电子邮件无效，其中EditText电子邮件包含以下内容：

android.support.v7.widget.AppCompatEditText{b014ce3 VFED..CL. .F...... 56,646-1384,804 #7f0d0096 app:id/etEmailLogin}

请帮我找出错误。

两个Toasts都显示相同的内容：

另外，请让我知道为什么会出现这种情况：

谢谢你的善意。

更新： 添加getText()和onCompleteListener后，消息会显示：

Answer 1

首先，确保Firebase控制台中的所有内容都很好（帐户都在那里等等）

目前似乎没有任何代码可以处理登录失败的情况。我刚刚在我的应用中使用Firebase实现了登录，因此这是我在用户按下登录按钮时使用的代码。 （注意：我刚刚注意到一个错误，在返回语句之前按钮没有设置为可单击，但除此之外一切都很好）

//    authenticates user, and starts main activity if successful
@OnClick(R.id.login_button)
public void login(View view) {

//        prevents the user launching the main activity multiple times if their login is valid
    loginButton.setClickable(false);

    String email = null;
    String pass = null;


    //        prevents null entries for email
    if (usernameInput.getText().length() != 0) {
        email = usernameInput.getText().toString();
    } else {
        Toast.makeText(LoginScreen.this, "Please enter your email",
                Toast.LENGTH_SHORT).show();
        return;
    }

    //        prevents null entries for pass
    if (passwordInput.getText().length() != 0) {
        pass = passwordInput.getText().toString();
    } else {
        Toast.makeText(LoginScreen.this, "Please enter your password",
                Toast.LENGTH_SHORT).show();
        return;
    }


//        signs in with the entered email and pass
    AuthManager.firebaseAuth.signInWithEmailAndPassword(email,pass)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
//                        sign in success
                    Log.v(TAG, "signIn:onComplete:" + task.isSuccessful());

//                        if sign in is successful, pass auth info to global variables, and launch intent and start the main activity
                    if (task.isSuccessful()){

                        AuthManager.user = AuthManager.firebaseAuth.getCurrentUser();
                        AuthManager.userUID = AuthManager.user.getUid();
                        AuthManager.loggedIn = true;
//                            creates the DB manager to make initial and future DB calls
                        new DBManager();

                        Toast.makeText(LoginScreen.this, "Signed in",
                                Toast.LENGTH_SHORT).show();
                        startMainActivity();
                    } else {
//                            if sign in fails
                        Log.w(TAG, "signIn", task.getException());
                        Toast.makeText(LoginScreen.this, "Incorrect username or password",
                                Toast.LENGTH_SHORT).show();
//                            makes the button clickable again
                        loginButton.setClickable(true);

                    }

                }
            });

}

我在我的实现中也使用了一个自定义的AuthManager类，但是你设置FirebaseAuth对象的方式完全没问题。

Answer 2

返回的异常代码ERROR_INVALID_EMAIL表示您作为电子邮件地址传递给signInWithEmailAndPassword()的字符串不具有有效电子邮件地址的格式。

检查logcat输出，查看Log.d(TAG, emaill)的记录内容。如果您认为有效地址，请发布值。

<强>更新

问题在于这些陈述：

final String passwordl = etPasswordLogin.toString().trim();
final String emaill = etEmailLogin.toString().trim();

你想要这样的东西：

final String passwordl = etPasswordLogin.getText().toString().trim();
final String emaill = etEmailLogin.getText().toString().trim();

更新2：

完成建议的更正后，您的signin()方法应如下所示：

public void signIn() {
    final String passwordl = etPasswordLogin.getText().toString().trim(); //NOTE addition of getText()
    final String emaill = etEmailLogin.getText().toString().trim(); //NOTE addition of getText()

    FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
    Toast.makeText(LoginActivity.this, user.getEmail()+"; "+    (findViewById(R.id.etEmailLogin)).toString().trim(), Toast.LENGTH_LONG).show();
    Log.d(TAG, emaill);

    mAuth.signInWithEmailAndPassword(emaill, passwordl);
    Intent in = new Intent(LoginActivity.this, WelcomeActivity.class);
    startActivity(in);
};

Log.d(TAG, emaill)的输出应该是您输入的有效电子邮件地址，例如myName@domainName。如果日志输出不是您输入的电子邮件地址，请发布记录的值并重新发布signin()的代码。
