I write the click in the adapter.(This adapter deal with an image and a text.)

class  FruitAdapter (val fruitList:List<Fruit>)://Fruit is a data class for an image with its text
    RecyclerView.Adapter<FruitAdapter.ViewHolder>() {
    //not very important here I guess   
    inner class ViewHolder(view: View) : RecyclerView.ViewHolder(view) {
        val fruitImage: ImageView = view.findViewById(R.id.fruitImage)
        val fruitName: TextView = view.findViewById(R.id.fruitName)
    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val view = LayoutInflater.from(parent.context)
            .inflate(R.layout.fruit_item, parent, false)
        val viewholder=ViewHolder(view)    
        viewholder.fruitImage.setOnClickListener{
            //here I try to get the position
            val position=viewholder.absoluteAdapterPosition 
            Log.e("a",position.toString())}

...
}

and it just output -1 to me in logcat, why??

I try to change the “.absoluteAdapterPosition” to “.bindingAdapterPosition” or “.layoutPosition”, but they all -1.
