    inner class ViewHolder1(private val mView: View) : RecyclerView.ViewHolder(mView) {

        fun bind(item: DummyItem) {
            mView.setBackgroundColor(Color.BLUE)
            
            mView.txtAdresFrom.text = item.content
            mView.txtAdresTo.text = item.details
            mView.txtPrice.text = "150 TL"
        }
    }

    inner class ViewHolder2(private val mView: View) : RecyclerView.ViewHolder(mView) {
        fun bind(item: DummyItem) {
            mView.EditText_TCKN.setText("Selam Naber")
        }
    }

    companion object {
        @JvmStatic
        fun DIFF_CALLBACK(): DiffUtil.ItemCallback<DummyItem> = object : DiffUtil.ItemCallback<DummyItem>() {
            override fun areItemsTheSame(oldItem: DummyItem?, newItem: DummyItem?): Boolean {
                return oldItem?.id == newItem?.id
            }

            override fun areContentsTheSame(oldItem: DummyItem?, newItem: DummyItem?): Boolean {
                return (oldItem?.content == newItem?.content) && oldItem?.details == newItem?.details
            }
        }
    }

}

non of this code will work

 mView.setBackgroundColor(Color.BLUE)
        
        mView.txtAdresFrom.text = item.content
        mView.txtAdresTo.text = item.details
        mView.txtPrice.text = "150 TL"
