我想在 Kotlin 中保存和恢复 mutableList 或数组

问：

我有以下 mutableList

val rowsSavedList = mutableListOf<Int>()

The data is lost when the app changes from portrait to landscape. I save the rest of my data using onSaveInstanceState and restore with onRestoreInstanceState Is there a way to do this with the mutableList.

我尝试使用onSaveInstanceState和onRestoreInstanceState，但它不起作用。任何帮助将不胜感激。
