    @Override
    public View getView(final int position, View convertView, ViewGroup parent)
    {
        View view = convertView;

        final ViewHolder holder;

        if (view == null) 
        {

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

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

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

        if (holder.tvTitle != null && null != objBean.getTitle() && objBean.getTitle().trim().length() > 0)
