Answer 1

You can try this way

main activity

public void initialize(List> responseObjectList) {
    RecyclerView upperRecyclerView = (RecyclerView) this.findViewById(R.id.main_layout);
    upperRecyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
    VerticalAdapter adapter = new VerticalAdapter(this, responseObjectLists);
    upperRecyclerView.setAdapter(adapter);
    adapter.notifyDataSetChanged();
}

Vertical recycled view adapter

public class VerticalAdapter extends RecyclerView.Adapter {

    final private SearchActivity activity;
    List> list;

    public VerticalAdapter(SearchActivity activity, List> lists) {
        this.list = lists;
        this.activity = activity;
    }

    public Holder onCreateViewHolder(ViewGroup parent,int viewType) {
        View itemLayoutView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.vertical_layout, null);
        return new Holder(itemLayoutView);
    }

    public void onBindViewHolder(Holder viewHolder, int position) {
        List objectList = list.get(position);
        viewHolder.packageTitle.setText(objectList.get(0).getTag());
        ImageAdapter imageAdapter = new ImageAdapter(activity, objectList);
        viewHolder.horizontalRecyclerView.setLayoutManager(new LinearLayoutManager(activity, LinearLayoutManager.HORIZONTAL, false));
        viewHolder.horizontalRecyclerView.setAdapter(imageAdapter);
        viewHolder.horizontalRecyclerView.setNestedScrollingEnabled(false);
        imageAdapter.notifyDataSetChanged();
    }

    public final static class Holder extends RecyclerView.ViewHolder {

        protected TextView packageTitle;
        protected RecyclerView horizontalRecyclerView;

        public Holder(View view) {
            super(view);
            this.packageTitle = (TextView) view.findViewById(R.id.recycleViewTitle);
            this.horizontalRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
            this.horizontalRecyclerView.setLayoutManager(new LinearLayoutManager(this.horizontalRecyclerView.getContext(), LinearLayoutManager.HORIZONTAL, false));
            this.horizontalRecyclerView.setNestedScrollingEnabled(false);
            horizontalRecyclerView.setAdapter(null);
        }
    }

    public int getItemCount() {
        return ListUtil.isEmpty(list) ? 0 : list.size();
    }
}

Horizontal recycleview adapter

public class ImageAdapter extends     RecyclerView.Adapter {

    private List mainPageResponseList;
    private SearchActivity activity;

    public ImageAdapter(SearchActivity activity, List mainPageResponseList) {
        this.mainPageResponseList = mainPageResponseList;
        this.activity = activity;
    }

    public ImageAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemLayoutView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.horizontal_layout_view, null);
        ViewHolder viewHolder = new ViewHolder(itemLayoutView);
        return viewHolder;
    }

    public void onBindViewHolder(ViewHolder viewHolder, int position) {
        ResponseObject object = mainPageResponseList.get(position);
        Util.setImageUsingGlide(object.getImage(), viewHolder.imageView);
        viewHolder.packageName.setText(object.getDestination());
        viewHolder.packagePrice.setText(object.getPrice() + "");
        viewHolder.imageView.setOnClickListener(null);
    }

    public final static class ViewHolder extends RecyclerView.ViewHolder {

        protected ImageView imageView;
        protected TextView packageName;
        protected TextView packagePrice;

        public ViewHolder(View view) {
            super(view);
            this.imageView = (ImageView) view.findViewById(R.id.packageImage);
            this.packageName = (TextView) view.findViewById(R.id.packageName);
            this.packagePrice = (TextView) view.findViewById(R.id.packagePrice);
        }
    }

    public int getItemCount() {
        return ListUtil.isEmpty(mainPageResponseList) ? 0 : mainPageResponseList.size();
    }
}
