My app

Solution

  • You could create a function that maps drawable ids to string ids:

    @StringRes
fun getTextId(@DrawableRes drawableId: Int): Int =
    when (drawableId) {
        R.drawable.image_one -> R.string.text_one
        R.drawable.image_two -> R.string.text_two
        R.drawable.image_three -> R.string.text_three
        ...
        else -> error("unexpected drawable id")
    }

    The best solution will depend on exactly how you are choosing/displaying your random images.
