Kotlin 字符串替换功能对我不起作用？

Question

大家好，请帮助我，我正在尝试修改链接，但它不起作用。它正在使用 java，但最近我将 java 转换为 kotlin 并收到此错误。

我正在尝试使用当前登录用户电子邮件更改我在 [USER_ID] 中的链接 http://www.offertoro.com/click_track/api?offer_id=419393&pub_id=14&pub_app_id=5&USER_ID=[USER_ID]&GAID=[your_GAID]，但出现错误。

检查屏幕截图 Screenshot

错误

None of the following functions can be called with the arguments supplied.
CharSequence.replace(Regex, String) defined in kotlin.text
String.replace(String, String, Boolean = ...) defined in kotlin.text

我的代码

  fun modifyOfferLink() {
       val id = mAuth!!.currentUser!!.email
        // Modifying Offer Link Acording to Offer Partner
        when (partner) {
            "ogads" -> Finallink = link + "&aff_sub5=" + mAuth!!.currentUser!!.email
            "offertoro" -> Finallink = link.replace("[USER_ID]", mAuth!!.currentUser!!.email)
            "none" -> {
                Finallink = link!!.replace("[USER_ID]", mAuth!!.currentUser!!.email)
            }
            else -> Finallink = link.replace("[USER_ID]", mAuth!!.currentUser!!.email)
        }
    }

Answer 1

很可能没有完全是[USER_ID] 的子字符串。你确定不是["USER_ID"]？

您能否在调用替换之前打印link 的值。这可能会让我们和你看到问题。
