With these it helps I have a Custom view: , You have to add parent layout as parameter to 'inflate' method. class CustomerView(context: Context, attrs: AttributeSet) : LinearLayout(context, attrs) {
private var txtName: TextView
private var txtAge: TextView
init {
View.inflate(context, R.layout.view_customer, this)
txtName = findViewById(R.id.txtTestName)
txtAge = findViewById(R.id.txtTestAge)
txtName.text = "Derek"
txtAge.text = "23"
}
}

Edittext and textview inside recyclerview Android kotlin scrolling issue
Date : March 29 2020, 07:55 AM
To fix the issue you can do You need to have an array of quantities in the KartListAdapter to save the quantities. The values are disappearing an showing wrongly is because the views are getting recycled in the RecyclerView. So you need to save the sates of each row in a separate ArrayList and then show the quantities from there. Hence I would like to propose having a separate ArrayList in your KartListAdapter like var quantityList: List .holder.itemsqty.text = quantityList[position];
holder.btnIncrease.setOnClickListener() {
quantityList[position] = quantityList[position] + 1;
notifyDataSetChanged();
}
holder.btnDecrease.setOnClickListener() {
if(quantityList[position] > 0) {
quantityList[position] = quantityList[position] - 1;
notifyDataSetChanged();
}
}

I wish this help you I assume that the textview's id is movieCount and this is what you need inside the adapter. In your activity create this method: fun getCount(): String {
return movieCount.text.toString()
}
inner class MoviesAdapter(context: Context) : RecyclerView.Adapter<MoviesAdapter.MovieViewHolder>()
val activity: MainActivity = context as MainActivity
activity.getCount()
recyclerview.adapter = MoviesAdapter(this)
