Kotlin 中带参数的 Lambda

我想写TextWatcher几EditText秒。在其中任何一个中，我都想为EditText变量赋值。像这样：

var variable: String? = null

private inner class CodeTextWatcher : TextWatcher {
    override fun afterTextChanged(s: Editable?) {
        variable = s?.toString()
    }

    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
    }

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
    }
}

对于几个EditTexts 我想写一些类似的东西：

private inner class CodeTextWatcher(private val method: (String?) -> Unit) : TextWatcher {
    override fun afterTextChanged(s: Editable?) {
        method(s?.toString())
    }

    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
    }

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
    }
}

并称之为：

textWatcher1 = CodeTextWatcher {variable1 = s}
textWatcher2 = CodeTextWatcher {variable2 = s}

但是我不能s在这里写并且想s从afterTextChanged(s: Editable?). 是否有可能？
