Android Kotlin图标/图像变量

我有一个数据类，需要将图像/图标保存为变量。所以我可以在以后把它们放到ImageView中。有人知道怎么做吗？我的图像/图标是可绘制的。例如，ic_delete

这里是我的数据类：

data class Category(
    val id: EnumCategories,
    val name: String,
    val itemType: EnumTypes?,
    val icon: Image
)

val categories = listOf(

    Category(EnumCategories.CATEGORY01, "CATEGORY01", null, -> Here should be my image <-),
    Category(EnumCategories.CATEGORY02, "CATEGORY02", EnumTypes.TYPE1, -> Here should be my image <-),
    Category(EnumCategories.CATEGORY03, "CATEGORY03", EnumTypes.TYPE2, -> Here should be my image <-)
)

谢谢

取一个int，这样你就可以使用int了

data class Category(
    val id: EnumCategories,
    val name: String,
    val itemType: EnumTypes?,
    val icon: Int
)

并将图像另存为

val categories = listOf(

    Category(EnumCategories.CATEGORY01, "CATEGORY01", null, R.mipmap.ic_icon),
    ,...,..
)

使用val图标：Int

data class Category(
    val id: EnumCategories,
    val name: String,
    val itemType: EnumTypes?,
    val icon: Int
)

val categories = listOf(

    Category(EnumCategories.CATEGORY01, "CATEGORY01", null, R.mipmap.ic_icon),
    ,...,..
)
