如何在 Kotlin 中转换Array<String>为ArrayList<String>？

var categoryList : ArrayList<String>?=null
val list = arrayOf("None", "ABC")
categoryList = ArrayList(Arrays.asList(list))

我收到此错误：

错误

Type inference failed. Expected type mismatch: inferred type is kotlin.collections.ArrayList<Array<String>!> /* = java.util.ArrayList<Array<String>!> */ but kotlin.collections.ArrayList<String>? /* = java.util.ArrayList<String>? */ was expected
