Solution 1:

Glad you solved the issue. Below is the adapter code for 2nd solution:

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> implements Filterable {
private List<MenuItem> MenuItemsList;
private List<Integer> filteredId;
private RecyclerViewOnItemClick recyclerViewOnItemClick;

public RecyclerViewAdapter(List<MenuItem> nMenuItemsList, RecyclerViewOnItemClick NrecyclerViewOnItemClick) {
    this.MenuItemsList = nMenuItemsList;
    this.recyclerViewOnItemClick = NrecyclerViewOnItemClick;
    filteredId = new ArrayList<>();
    setDefaultIds(filteredId);
}

private void setDefaultIds(List<Integer> dataList) {
    dataList.clear();
    for (int i = 0; i < MenuItemsList.size(); i++) dataList.add(i);
}

@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.menu_item, parent, false);
    ViewHolder holder = new ViewHolder(view, recyclerViewOnItemClick);
    return holder;
}

@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
    MenuItem menuItem = MenuItemsList.get(filteredId.get(position));
    holder.image.setImageResource(menuItem.getImageResource());
    holder.imageName.setText(menuItem.getOilName());
}

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

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    ImageView image;
    TextView imageName;
    CardView parentLayout;
    RecyclerViewOnItemClick recyclerViewOnItemClick;

    public ViewHolder(@NonNull View itemView, RecyclerViewOnItemClick recyclerViewOnItemClick) {
        super(itemView);
        image = itemView.findViewById(R.id.image);
        imageName = itemView.findViewById(R.id.image_name);
        parentLayout = itemView.findViewById(R.id.RelativeLayout);
        this.recyclerViewOnItemClick = recyclerViewOnItemClick;
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        recyclerViewOnItemClick.onItemClick(filteredId.get(getAdapterPosition()));
    }
}

@Override
public Filter getFilter() {
    return filter;
}

private Filter filter = new Filter() {
    //run on background thread
    @Override
    protected FilterResults performFiltering(CharSequence charSequence) {
        List<Integer> filterList = new ArrayList<>();
        if (charSequence == null || charSequence.length() == 0) {
            // if search text is empty add all original list values to filterlist
            setDefaultIds(filterList);
        } else {
            String filterPattern = charSequence.toString().toLowerCase().trim();
            // Perform search on whole original list
            MenuItem menuu;
            for (int i = 0; i < MenuItemsList.size(); i++) {
                menuu = MenuItemsList.get(i);
                if (menuu.getOilName().toLowerCase().contains(filterPattern)) {
                    filterList.add(i);
                }
            }
        }
        FilterResults results = new FilterResults();
        results.values = filterList;
        return results;
    }

    //run on UI thread
    @Override
    protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
        filteredId.clear();
        filteredId.addAll((List<Integer>) filterResults.values);
        notifyDataSetChanged();
    }
};

public interface RecyclerViewOnItemClick {
    void onItemClick(int id);
}
}
