Question

我正在使用Firebase身份验证功能，但遇到了问题。我有两个活动，SignUpActivity.java和SignInActivity.java。注册帐户后，我将被重定向到登录活动，在其中输入我的凭据。但是，即使使用了正确的凭据，我仍然无法登录。以下是代码和屏幕截图

编辑：我仍然无法解决此问题。是否有人愿意帮助我？

SignUpActivity.java

public class SignUpActivity extends AppCompatActivity {
private EditText inputEmail, inputPassword;
private Button btnSignIn, btnSignUp, btnResetPassword;
private ProgressBar progressBar;
private FirebaseAuth auth;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_signup);

    auth = FirebaseAuth.getInstance();

    btnSignIn = (Button) findViewById(R.id.sign_in_button);
    btnSignUp = (Button) findViewById(R.id.sign_up_button);
    inputEmail = (EditText) findViewById(R.id.email);
    inputPassword = (EditText) findViewById(R.id.password);
    progressBar = (ProgressBar) findViewById(R.id.progressBar);
    btnResetPassword = (Button) findViewById(R.id.btn_reset_password);

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

    btnSignIn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(SignUpActivity.this, SignInActivity.class));
        }
    });

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

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

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

            if (password.length() < 6) {
                Toast.makeText(getApplicationContext(), "Password too short, enter minimum 6 characters!", Toast.LENGTH_SHORT).show();
                return;
            }

            // Progress bar beings loading
            progressBar.setVisibility(View.VISIBLE);

            createAccount(email, password);
        }
    });
}

public void createAccount(String email, String password) {
    auth.createUserWithEmailAndPassword(email, password)
            .addOnCompleteListener(SignUpActivity.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);
                    if (task.isSuccessful()) {
                        startActivity(new Intent(SignUpActivity.this, SignInActivity.class));
                        finish();
                    } else {
                        Toast.makeText(SignUpActivity.this, "Authentication failed." + task.getException(),
                                Toast.LENGTH_SHORT).show();
                    }
                }
            });
}
}

SignInActivity.java

public class SignInActivity extends AppCompatActivity {

private EditText inputEmail, inputPassword;
private FirebaseAuth auth;
private ProgressBar progressBar;
private Button btnSignup, btnLogin, btnReset;

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


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

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

    inputEmail = (EditText) findViewById(R.id.email);
    inputPassword = (EditText) findViewById(R.id.password);
    progressBar = (ProgressBar) findViewById(R.id.progressBar);
    btnSignup = (Button) findViewById(R.id.btn_signup);
    btnLogin = (Button) findViewById(R.id.btn_login);
    btnReset = (Button) findViewById(R.id.btn_reset_password);

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

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

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

    btnLogin.setOnClickListener(new View.OnClickListener() {

        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(SignInActivity.this, new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            progressBar.setVisibility(View.GONE);
                            if (task.isSuccessful()) {
                                Intent intent = new Intent(SignInActivity.this, MainActivity.class);
                                startActivity(intent);
                                finish();

                            } else {
                                // there was an error
                                if (password.length() < 6) {
                                    inputPassword.setError(getString(R.string.minimum_password));
                                } else {
                                    Toast.makeText(SignInActivity.this, getString(R.string.auth_failed), Toast.LENGTH_LONG).show();
                                }
                            }
                        }
                    });
        }
    });
