How to Modify Only First Nested RecyclerView (child) element at Position 0 of Parent RecyclerView?

I have parentRecyclerview that includes a nestedRecyclerview. nestedRecyclerView lists several items: (Apple, Banana, Pear). I want to bold the first item (apple) of this nestedRecyclerview like so:

**Apple**
Banana
Pear

-------

Apple
Banana
Pear

-------

Apple
Banana
Pear

I can get it to bold the first item of each nested recyclerview list by doing:

when (position) {
0 -> 
// code to make apple bold
}

but that gives me:

**Apple**
Banana
Pear

-------

**Apple**
Banana
Pear

-------

**Appla**
Banana
Pear

How do I go about this? I would add all my code, but honestly it is a ton of code and much more complex that apples, bananas, pears. I prefer code in Kotlin, but I can figure out Java if thats what you know. Thanks!

Lots of internet searching done, but most talk about onClickListener events.

try using this create variable to manage bold of view based on position

class NestedAdapter(...) {
private var topItemBold = false

override fun onBindViewHolder(holder: NestedViewHolder, position: Int) {
    val item = items[position]

    if (topItemBold && position == 0) {
        holder.textView.setTypeface(null, Typeface.BOLD)
    } else {
        holder.textView.setTypeface(null, Typeface.NORMAL)
    }

    // ... rest of your binding logic
}

and update your parent adapter like this

class ParentAdapter(...) {
override fun onBindViewHolder(holder: ParentViewHolder, position: Int) {

    val nestedAdapter = holder.nestedRecyclerView.adapter as NestedAdapter

    if (position == 0) {
        nestedAdapter.topItemBold = true
    } else {
        nestedAdapter.topItemBold = false
    }
}

so in above our topItemBold only true for first item on nested view on first item of parent list
