使用 Firebase 通过电子邮件和密码对用户进行身份验证

Question

我正在尝试为我的应用使用 Firebase 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(电子邮件，密码(.addOnCompleteListener...

当我为onCompleteListener创建一个抽象的内部类时，它会编译但onClick不会启动，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：没有点击声音，就像我在单击ontextview切换到登录屏幕或文本视图切换回注册页面时听到的声音。不会触发任何事件。

我做错了什么，我已经阅读了我能找到的所有文档......

Answer 1

添加 addonSuccessListener 而不是 onComplete
