class ListMoviesAdapter(
private val movies: MutableList<Item>,
) :
RecyclerView.Adapter<ViewHolder>() {
inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var contentImage: ImageView? = itemView.findViewById(R.id.contentImage)
var contentTitle: TextView? = itemView.findViewById(R.id.contentTitle)
var contentSubTitle1: TextView? = itemView.findViewById(R.id.contentSubtitle1)
}
interface onItemClickListener {
fun onItemCLick(position: Int)
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val inflater = LayoutInflater.from(parent.context)
val view = inflater.inflate(R.layout.item_6, parent, false)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val MoviesData: Item = movies.get(position)
holder.contentImage?.let {
Glide.with(it)
.load(MoviesData.media.thumbnail)
.fitCenter()
.into(holder.contentImage!!)
}
holder.contentImage?.setOnClickListener {
val moviesFragment = MoviesFragment()
val bottomsheet = DetailsFragment()
bottomsheet.show(moviesFragment.requireActivity().supportFragmentManager,"Bottomsheet")
Toast.makeText(holder.itemView.context, MoviesData.text.title, Toast.LENGTH_LONG).show()
}
holder.contentTitle?.text = MoviesData.text.title
holder.contentSubTitle1?.text = MoviesData.text.subtitle1
}
override fun getItemCount(): Int {
return movies.size
}
}
this is bottom sheet
override fun onCreate(savedInstanceState: Bundle?) {

setupView()
getMovieList()
adapter.addImageslider(slider)

}
fun addmovielist(movies: MutableList<Item>) {
adapter.addImageslider(movies)
}
private fun getMovieList() {
val apicall = Retrofit.Builder()

.create(Api::class.java)
val moviedata = apicall.GetMovieList()
moviedata.enqueue(object : Callback<ImageSLider> {

val size = responeBody.page.body.rows.size - 1

}
movies_list(list_movies)
}
override fun onFailure(call: Call<ImageSLider>, t: Throwable) {
Toast.makeText(requireActivity(), t.toString(), Toast.LENGTH_LONG).show()
}
})
}
@SuppressLint("NotifyDataSetChanged")

LinearLayoutManager(requireContext(), LinearLayoutManager.HORIZONTAL, false)
movie_recycle.adapter = ContentAdapter(all_movies)

}
this is nested recyclerview
class ContentAdapter(val item: MutableList<Rows>) :

var itemlist: MutableList<Item> = mutableListOf()
class ContentAdapterVH(itemView: View?) : RecyclerView.ViewHolder(itemView!!) {

val dashboardScreen = DashboardScreen()
val moviesFragment = MoviesFragment()
fun bind(data: Rows) {
recycleMovie?.apply {
recycleMovie.adapter = ListMoviesAdapter(data.items, moviesFragment)
layoutManager = LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false)
}
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ContentAdapterVH {
val inflater = LayoutInflater.from(parent.context)
val view = inflater.inflate(R.layout.item_6_list, parent, false)
return ContentAdapterVH(view)
}
override fun onBindViewHolder(holder: ContentAdapterVH, position: Int) {
val contentData: Rows = item.get(position)
holder.categoryText?.text = contentData.text.title
holder.bind(contentData)
}
override fun getItemCount(): Int {
return item.size
}
}
please help to solve this or give any link to refer this thank you

Just create a object class and create a method for bottom sheet and pass the context to this method. And from adapter, call this method on click on the item or where you want to display the bottom sheet Simple way is that you have to set click listener on onBindViewHolder method in adapter and directly call this showBottomSheet method. And pass the required data to it for displaying is in bottom sheet
object BottomSheetUtils {
fun showBottomSheet(
fragment: Fragment
) {
val bottomSheetDialog = BottomSheetDialog(fragment.requireContext())
bottomSheetDialog.setContentView(R.layout.your_custom_bottom_sheet_layout)
// Just update UI and set click listeners etc...
bottomSheetDialog.textviewName.text = "Example"
bottomSheetDialog.show()
}
}

I Pass appcompactivity to the bottom adapter and trigger the bottom sheet using support fragment manager thank you all
