如何使用Moshi将json中的int列表转换为枚举列表/数组？

enum class Color {
    RED,
    GREEN,
    BLUE
}

class EnumListAdapter<T : Enum<T>> private constructor(private val enumClass: Class<T>) : JsonAdapter<List<T>>() {

    @FromJson
    override fun fromJson(reader: JsonReader): List<T>? {
        if (reader.peek() == JsonReader.Token.BEGIN_ARRAY) {
            val list = mutableListOf<T>()
            reader.beginArray()
            while (reader.hasNext()) {
                val intValue = reader.nextInt()
                val enumValue = enumClass.enumConstants[intValue]
                list.add(enumValue)
            }
            reader.endArray()
            return list
        }
        return null
    }

    @ToJson
    override fun toJson(writer: JsonWriter, value: List<T>?) {
        if (value != null) {
            writer.beginArray()
            for (enumValue in value) {
                val intValue = enumValue.ordinal
                writer.value(intValue)
            }
            writer.endArray()
        } else {
            writer.nullValue()
        }
    }

    companion object {
        fun <T : Enum<T>> create(enumClass: Class<T>): EnumListAdapter<T> {
            return EnumListAdapter(enumClass)
        }
    }
}

val moshi = Moshi.Builder()
    .add(EnumListAdapter.create(Color::class.java))
    .build()

val json = "[0, 1, 2]"
val adapter = moshi.adapter<List<Color>>()
val colors = adapter.fromJson(json)
