最后，我认识到Room需要在类型转换器实现中进行一些特殊更改(更改为ArrayList<HashMap<String, OtherServiceEntity>>).尽管如此，还是不​​知道这是一个功能或错误，因为在其他情况下，我仍然可以使用List作为类型.这就是我所做的细节，现在我可以运行它了

Finally, I recognized that Room needs some special change in type converter implementation (change to ArrayList<HashMap<String, OtherServiceEntity>>). Still, don't know it is a feature or bug because other cases I am still able to use List as type. This is the detail what I did, and now I am able to run it

@Entity(tableName = "ProfileEntities")
data class ProfileEntity(
        @TypeConverters(ProfileTypeConverter::class)
        @SerializedName("details") var details: List<ProfileDetailEntity> = listOf(),
        @Embedded
        @SerializedName("images") var images: ProfileImagesEntity = ProfileImagesEntity(),
        @PrimaryKey
        @SerializedName("masterId") var masterId: Long = 0,
        @TypeConverters(OtherServicesTypeConverter::class)
        @SerializedName("otherServices") var otherServices: ArrayList<HashMap<String, OtherServiceEntity>> = arrayListOf(),
        @SerializedName("updatedAt") var updatedAt: String = ""
)

以及转换器的实现

class ProfileTypeConverter {
    private val gson = Gson()
    @TypeConverter
    fun stringToList(data: String?): List<ProfileDetailEntity> {
        if (data == null) {
            return Collections.emptyList()
        }

        val listType = object : TypeToken<List<ProfileDetailEntity>>() {

        }.type

        return gson.fromJson<List<ProfileDetailEntity>>(data, listType)
    }

    @TypeConverter
    fun listToString(someObjects: List<ProfileDetailEntity>): String {
        return gson.toJson(someObjects)
    }
}

class OtherServicesTypeConverter {
    private val gson = Gson()
    @TypeConverter
    fun stringToList(data: String?): ArrayList<HashMap<String, OtherServiceEntity>> {
        if (data == null) {
            return ArrayList()
        }

        val listType = object : TypeToken<ArrayList<HashMap<String, OtherServiceEntity>>>() {

        }.type

        return gson.fromJson<ArrayList<HashMap<String, OtherServiceEntity>>>(data, listType)
    }

    @TypeConverter
    fun listToString(objects: ArrayList<HashMap<String, OtherServiceEntity>>): String {
        return gson.toJson(objects)
    }
}

祝您编程愉快！
