Something like this:

var adapterType1 = adapter1
var adapterType2 = adapter2

lvFoods2.adapter = when (lvFoods2.adapter) {
    adapterType1 -> FoodAdapter(listOfFoods2, this).also { adapterType1 = it }
    adapterType2 -> FoodAdapter2(listOfFoods3, this).also { adapterType2 = it }
    else -> lvFoods2.adapter
}
