java - 在Firebase上注册帐户后，用户如何在验证电子邮件之前无法登录？

Question

我的登录帐户有问题。注册帐户后，Firebase 将验证发送到我注册的电子邮件。然后，应用程序通过 toast 通知用户必须检查电子邮件。如果用户不验证电子邮件，他们将无法登录应用程序，但情况正好相反。不验证就可以登录注册邮箱，估计邮箱验证没用

所以，有一些来自 Register Activity.java 类的代码，我在其中嵌入了用于验证的代码，还有用于登录逻辑的 Login Activity.java

我希望输出是用户在验证电子邮件之前无法登录，但我在 3 个月内找不到有效的代码:)谢谢

使用这个:

if(user!=null && user.isEmailVerified()){
    // Add your stuff here
}else{
    // Not Authenticated User Message
}

引用this
