How do I access a textview Id from recyclerView in fragment class?

I have a recycler view and a XML file for the recycler view. I have used the recycler views inside the fragment layout. I want to access the textview id from the fragment activity for using fragment transactions.

    var titleTextView = view.findViewById<TextView>(R.id.tvTitle)
val subjectFragment = SubjectFragment()
println(titleTextView.text)

the above code provides a null pointer exception

I want to use the fragment manager to use the transactions and switch layouts

//            var fragment = parentFragmentManager?.beginTransaction()
//            fragment?.replace(R.id.newsFrameLayout, subjectFragment)
//            fragment?.commit()

but I cannot seem to access the textview id from the fragment class.

This is the xml layout used in the recycler view of the app

EDIT***

Solved it by using the onClickListener on textview in the adapter class onBindViewHolder function and used activity context for calling the supportFragmentManager.

When you use a recyclerview there isn't a unique tvtitle id available. For each item in the recyclerview there is a tvtitle.
Although you can aceess each of them from the recyclerview adapter.

If you want to access any item of recyclerview then you need to create a event at onBindViewHolder .
Use interface or lambda funtion for getting every view inside activity or fragment.

if you want views when click event happen then implement clickListener.

You should have some item click listner in your adapter class this way:

interface ItemClickListener {
fun onClick(dataYouWantInFragment:String) // or of any type
}

Then you should ask for the interface implementation of your fragment in your adapter class like below:

class YourRVAdapter(private val listener:ItemClickListener) {
override fun onBindViewHolder(holder:YourViewHolder,position:Int) {
holder.bindData(dataForPosition(position),listener)
}
class YourViewHolder(private val view:View) : RecyclerView.ViewHolder(view) {
private val tvTitle = view.findViewById<TextView>(R.id.tvTitle)
fun bindData(data:String,listener:ItemClickListener) {
tvTitle.text = data
view.setOnClickListener {
listener.onClick(tvTitle.text.toString())// pass the data you want in fragment
}
}
}
// If you used binding,
class YourViewHolder(private val binding:YourBinding) : RecyclerView.ViewHolder(binding.root) {
fun bindData(data:String,listener:ItemClickListener) {
binding.tvTitle.text = data
binding.root.setOnClickListener {
listener.onClick(tvTitle.text.toString())// pass the data you want in fragment
}
}
}
}

in your fragment class, you should implement that listener interface like below:

class YourFragmentClass() : ItemClickListener {
override fun onCreateView(...) {
..
recyclerView.adapter = YourRVAdapter(this)
..
}
override fun onClick(dataYouWant:String) {
// use this data for your fragment transaction
childFragmentManager.beginTransaction().add/replace()....commit()
}
}

Now, you should be able to get the onClick() callback in your fragment class with you desired data when you click on a recycler view item.
