        this.activity = act;

        this.row = resource;

        this.items = arrayList;

        /*options = new DisplayImageOptions.Builder().showStubImage(R.drawable.blank).showImageForEmptyUrl(R.drawable.blank).cacheInMemory().cacheOnDisc().build();

        imageLoader = ImageLoader.getInstance();
                */

            holder = new ViewHolder();

            view.setTag(holder);

        {
            holder = (ViewHolder) view.getTag();
        }

        if ((items == null) || ((position + 1) > items.size()))

            return view;

        objBean = items.get(position);

        holder.tvTitle = (TextView) view.findViewById(R.id.tvtitle);

        holder.tvDesc = (TextView) view.findViewById(R.id.tvdesc);

        holder.tvDate = (TextView) view.findViewById(R.id.tvdate);

        holder.imgView = (ImageView) view.findViewById(R.id.image);

        holder.pbar = (ProgressBar) view.findViewById(R.id.pbar);
