    View row = convertView;
    ViewHolder holder = null;

    if (row == null) {
        LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
        row = inflater.inflate(mLayoutResourceId, parent, false);
        holder = new ViewHolder();
        holder.image = (ImageView) row.findViewById(R.id.upload_item_image);
        holder.progressUpdate = (ProgressBar) row

    item.setProgressListener(new ProgressListener() {

        @Override
        public void onProgress(int progress) {
            holder.progressUpdate.setProgress(item.getProgress());
        }
    });
    holder.progressUpdate.setProgress(item.getProgress());
    return row;
}

static class ViewHolder {
    ImageView image;
    ProgressBar progressUpdate;
}

public void updateListFileToUpdate(List<Upload> listFileToUpload) {
    this.listFileToUpload = listFileToUpload;
}

@Override
public int getCount() {
    return listFileToUpload.size();
}

@Override
public Upload getItem(int location) {
    return listFileToUpload.get(location);
}

@Override
public long getItemId(int position) {
    return 0;
