}

/**

 */
public static class ItemViewHolder extends RecyclerView.ViewHolder {

    public final TextView textView;
    public final ImageView handleView;

    public ItemViewHolder(View itemView) {
        super(itemView);
        textView = (TextView) itemView.findViewById(R.id.text);
        handleView = (ImageView) itemView.findViewById(R.id.handle);
    }
}
