Question

我实际上在这里做什么，当用户登录到他们的帐户时，然后我检查他们是否验证了他们的电子邮件地址，如果没有，则我正在启动EmailVerificationActivity。用户单击 SEND VERIFICATION EMAIL （发送验证电子邮件）按钮后，将从该位置将电子邮件验证代码发送到用户的电子邮件地址。

此后，当用户成功验证其电子邮件地址时，再次单击 SEND VERIFICATION LINK 按钮。

而不是显示吐司消息 Toast.makeText(this, "Your email has been verified, Now you can login.", Toast.LENGTH_LONG).show();，重新发送电子邮件验证链接。

为什么isEmailVerified()返回false条件。

这是我的 EmailVerificationActivity

Answer 1

您需要重新加载当前的用户信息。您会看到通过身份验证获得的用户数据很旧，您需要检索最新的数据。为此，请使用reload()方法。

我如何解决该错误。

private void isEmailVerified()
{
    mAuth.getCurrentUser().reload().addOnSuccessListener(new OnSuccessListener<Void>() {
        @Override
        public void onSuccess(Void aVoid) {
            if (mAuth.getCurrentUser()!=null)
            {
                boolean isEmailVerified = mAuth.getCurrentUser().isEmailVerified();
                if (isEmailVerified)
                {
                    Toast.makeText(getApplicationContext(), "Your email has been verified, Now you can login.", Toast.LENGTH_LONG).show();
                }
                else
                {
                    sendVerificationEmail();
                }
            }
        }
    });
}

在isEmailVerified（）的每次调用上返回错误条件，即使在验证电子邮件之后
