Enums or sealed classes with strings

Question

Can I create an enum or a sealed class in Kotlin that contain string resources?

For instance, I have this class:

private enum class Item(
    val id: Int,
    @DrawableRes val imageRes: Int,
    val title: String
) {
    PURSE(1, R.drawable.ic_card, "My balance"),
    MESSAGES(2, R.drawable.ic_bell, "Messages")
}

If I add a field val resources: Resources in the constructor, I cannot set a parameter resources, so cannot use string resources from strings.xml. In this case I cannot use localization for enums.

You don't need a Resources instance. You can use a string resource, like you did for the drawable:

private enum class Item(
    val id: Int,
    @DrawableRes val imageRes: Int,
    @StringRes val title: Int
)
