I have an ExoPlayer instance within a RecyclerView in my Android app. While the player works perfectly with the next and previous buttons, I’m facing an issue where the videos don’t switch correctly when I swipe left or right on the RecyclerView. Instead, I just see a blank space where the next or previous video should be and audio of previous video.

RecyclerView class

public class Onclick_MediaViewer extends Fragment  {

    int pos;
    ArrayList<String> galleryItems;
    PlayerView video;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        galleryItems = new ArrayList<>();
        return inflater.inflate(R.layout.onclick_mediaviewer,container,false);

    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        RecyclerView recyclerView = view.findViewById(R.id.mediaViewerRecycler);
        layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
        SnapHelper snapHelper = new PagerSnapHelper();
        recyclerView.setLayoutManager(layoutManager);
        snapHelper.attachToRecyclerView(recyclerView);
        recyclerView.addItemDecoration(new LinePagerIndicatorDecoration());
        Media_OnclickAdapter adapter = new Media_OnclickAdapter();
        recyclerView.setHasFixedSize(true);
        recyclerView.setAdapter(adapter);
        
        recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                if (newState == RecyclerView.SCROLL_STATE_IDLE){
                    //Handle new video
                    int pos = layoutManager.findFirstCompletelyVisibleItemPosition();
                    // I can see update on position here which i can use to switch video
                    Log.d(TAG, "onScrollStateChanged: "+pos);
                }
            }
        });


    }

    private class Media_OnclickAdapter extends RecyclerView.Adapter<Media_OnclickAdapter.Viewholder>{


        @NonNull
        @Override
        public Viewholder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(getActivity()).inflate(R.layout.onclick_mediaviewer_video,parent,false);
            return new Viewholder(view);
        }

        @Override
        public void onBindViewHolder(@NonNull Viewholder holder, int position) {
            Log.d(TAG,"Type == "+holder.getItemViewType());
            pos = holder.getAbsoluteAdapterPosition();
            ExoplayerSingle_Instance.getInstance()
                            .prepareExoPlayer(getActivity(),video,galleryItems);
        }

        @Override
        public int getItemCount() {
            return galleryItems.size();
        }

       

        private class Viewholder extends RecyclerView.ViewHolder {
            public Viewholder(@NonNull View itemView) {
                super(itemView);
                video = itemView.findViewById(R.id.onclickMediaViewer_Video);

            }
        }
    }

}
