call getter method in adapter class

I've built a recyclerview, which displays a list of some data. Now i want to commit the data of the clicked list element to a new detail activity via intent.putExtra.

I don't know how to call my getter methods of my data for each list element in the onClick event of the adapter class.

Here is my adapter code:

public class BarsItemAdapter extends RecyclerView.Adapter<BarsItemAdapter.ListItemViewHolder> {

    private ArrayList<BarsItem> listData;

    private static Context sContext;

    public static class ListItemViewHolder extends RecyclerView.ViewHolder
            implements OnClickListener  {
        public TextView nameView;
        public TextView adresseView;
        public TextView typView;
        public TextView bewertungView;


        public ListItemViewHolder (View itemView){
            super(itemView);
            nameView = (TextView) itemView.findViewById(R.id.name);
            adresseView = (TextView) itemView.findViewById(R.id.adresse);
            typView = (TextView) itemView.findViewById(R.id.typ);
            bewertungView = (TextView) itemView.findViewById(R.id.bewertung);
            itemView.setOnClickListener(this);
        } // end constructor

        @Override
        public void onClick (View v) {
            Intent intent = new Intent(sContext,ActivityDetail.class);
            // HERE I WANT TO COMMIT MY DATA
            sContext.startActivity(intent);
        }

    } // end class ListItemViewHolder

    public BarsItemAdapter(ArrayList<BarsItem> list) {
        this.listData = list;
    }

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

    @Override
    public void onBindViewHolder(ListItemViewHolder holder, int position) {
        BarsItem ni = listData.get(position);
        holder.nameView.setText(ni.getName());
        holder.adresseView.setText(ni.getAdresse());
        holder.typView.setText(ni.getTyp());
        holder.bewertungView.setText(ni.getBewertung());
    } // end onBind

    @Override
    public ListItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.list_row_layout, parent, false);
        itemView.setPadding(10,5,10,5); // left top right bottom
        sContext = parent.getContext();
        return new ListItemViewHolder(itemView);
    } // end onCreate

}

The getter and setter methods are in a external file named "BarsItem.java"

Thanks for your help!
