Question

完成帐户创建活动后，firebase不会创建该帐户，并显示尚未创建新用户。我查看了Firebase网站上的文档，但似乎无法理解我所缺少的内容。下面是负责帐户创建的功能。

我还检查了android studio是否具有所有firebase SDK的最新版本，以及我是否已使用firebase助手正确配置了项目。

在我的onClick函数中，也会因为我的异常错误而受到影响。我在我的registerAction（）和onClick（）函数中都强调了有问题的行。

    public void onClick(View v) {
    switch (v.getId()) {
        case R.id.registerButton:
        registerAction(EmailField.getText().toString(), PasswordField.getText().toString()); **Error handles here**
        break;

        case R.id.loginButton:
            loginAction(EmailField.getText().toString(), PasswordField.getText().toString());
            break;

        case R.id.resendConfirmationButton:
            confirmAction();
            break;

        case R.id.resetButton:
            resetAction();
            break;

        case R.id.forgotButton:
            forgotPasswordAction(EmailField.getText().toString());
            break;

        case R.id.showLoginButton:
            showLoginAction(true);
            break;

        case R.id.showRegisterButton:
            showRegisterAction(true);
            break;
    }

}
 private void registerAction() {
      String email = EmailField.getText().toString();
      String password = PasswordField.getText().toString();

// This sends the users email and password to firebase to save as a token.
    Log.d(TAG, "Create user account: " + email);
    mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { **Error also occurs here**
    @Override
    public void onComplete(@NonNull Task<AuthResult> task) {
        if(task.isSuccessful()) {
            // This is called when the user registration as expected.
            Log.d(TAG, "CreatedUserWithEmail:success");
            Toast.makeText(AuthenticationActivity.this, "Registration was successful", Toast.LENGTH_LONG).show();
            mAuth.getCurrentUser();
        } else {
            // In the event that user authentication fails.
            Log.w(TAG, "CreatedWithEmail:failure", task.getException());
            Toast.makeText(AuthenticationActivity.this, "User registration has failed", Toast.LENGTH_LONG).show();
        }
    }
});

运行代码后，Android Studio会返回此异常：

Answer 1

您写错了Case：

case R.id.registerButton:
        registerAction();
        break;

说明：

您的Switch案例包含registerAction方法/函数，不带任何参数。

我建议在registerAction中输入Null，以检查用户是否未输入值。应用程序将崩溃
