view not created for fragment of viewpager inside recyclerview - kotlin

Question

I want to make Home screen like Instagram where video will play/pause on horizontal and vertical scrolling.
For that I am using fragment inside viewpager and viewpager inside recyclerview for achieving horizontal and vertical scrolling.
Issue is that for second item of recyclerview view of fragment is not created.
can anyone help me to achieve this functionality.
Thanks in advance.
Below is the adapter class of recyclerview.
class DashboardFeedsAdapterNew(
private val mContext: Context, var mList: ArrayList<PostListModel.PostListData>,
private val viewHolderClicks: ViewHolderClicks,
) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {
var mInflater: LayoutInflater =
mContext.getSystemService(Activity.LAYOUT_INFLATER_SERVICE) as LayoutInflater
var mActivePage = 0
private var isLoadingAdded = false
val LOADING_TYPE = 0
val POST_TYPE = 1
val STORY_TYPE = 2
fun getList(): ArrayList<PostListModel.PostListData> {
return mList
}
override fun onCreateViewHolder(
parent: ViewGroup,
viewType: Int
): RecyclerView.ViewHolder {
when (viewType) {
POST_TYPE -> {
val v = LayoutInflater.from(parent.context)
.inflate(R.layout.raw_feed, parent, false)
return PostViewHolder(v)
}
}
val v =
mInflater.inflate(R.layout.raw_feed, parent, false)
return PostViewHolder(
v
)
}
override fun getItemViewType(position: Int): Int {
if(position == mList.size -1 && isLoadingAdded) {
return LOADING_TYPE
} else {
/*if ((position + 1) % 5 == 0) {
return STORY_TYPE
}*/
return POST_TYPE
}
}
override fun onBindViewHolder(
holder: RecyclerView.ViewHolder,
position: Int
) {
val model = mList[holder.adapterPosition]
if (holder is PostViewHolder) {
//post type
try {
if (model.files.isNotEmpty()) {
setupViewpager(holder, model)
}
} catch (e: Exception) {
e.printStackTrace()
}
}
}
private fun setupViewpager(binding: PostViewHolder, model: PostListModel.PostListData) {
binding.vpAttachment.adapter = ViewPagerAdapter((activityContext() as AppCompatActivity).supportFragmentManager,model)
binding.vpAttachment.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
override fun onPageScrolled(
position: Int,
positionOffset: Float,
positionOffsetPixels: Int
) {
mActivePage = binding.vpAttachment.currentItem
}
override fun onPageSelected(position: Int) {
}
override fun onPageScrollStateChanged(state: Int) {}
})
}
inner class ViewPagerAdapter(fm: FragmentManager, val mData: PostListModel.PostListData) :
FragmentStatePagerAdapter(fm, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT ) { //FragmentPagerAdapter
