使用 Firebase 通过电子邮件和密码对用户进行身份验证

Question

我正在尝试使用 Firebase 为我的应用建立用户身份验证，运行以下代码，我得到：

错误：找不到符号 mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener...

当我为onCompleteListener 创建一个抽象内部类时，它编译但onClick 没有启动，因为当您单击注册按钮时没有任何反应，甚至没有错误消息。我定义了Toast.makeText(SignUpActivity.this, "Error !" + task.getException().getMessage(), Toast.LENGTH_SHORT).show();，没有任何反应：当点击ontextview切换到登录屏幕或文本视图切换回注册页面时，没有像我听到的点击声音。没有事件被触发。

我做错了什么我已经阅读了我能找到的所有文档......

添加 addonSuccessListener 而不是 onComplete
