kotlin how do i make a function for that?-CodePudding

I have this screen, I need appropriate text for each r.drawable that is seen in random mode, in each imageview, I wrote the app in KOTLIN and I'm almost done, I just need this text resource explaining the displayed image , to each image its text, can you help me? thank you

I don't know how to create a text that changes according to the image

private lateinit var listId: List<Int>


 private fun pickNumber (){
        val (id1, id2, id3) = listId.shuffled()
        binding.imageView.setImageResource(id1)
        binding.imageView2.setImageResource(id2)
        binding.imageView3.setImageResource(id3)
        
        private fun initializeList() {
        listId = listOf(
            R.drawable.r02 ,
            R.drawable.w02s,
            R.drawable.ror,
            R.drawable.rands,
            R.drawable.rups,
            R.drawable.rles,
            R.drawable.rsw)

The easiest way for you to link each text resource to appropriate image resourse is to change type of listId variable from List<Int> to Map<Int, Int>. Now it will contain pairs of image resources and text resources. Also you should change listOf(...) method to mapOf(R.drawable.desired_drawable to R.string.desired_text, ...) and listId.shuffled() to listId.toList().shuffled(). After this you can just operate with gained pairs of values to set them to corresponding views.
