 @Override

        public View getView(int position, View convertView, ViewGroup parent) {

            ViewHolder viewHolder = null;

            if (convertView == null) {

                convertView = View.inflate(getActivity(), R.layout.lv_item,

                        null);

                viewHolder = new ViewHolder();

                convertView.setTag(viewHolder);

                viewHolder.lv_imageView = (ImageView) convertView

                        .findViewById(R.id.lv_imageView);

                viewHolder.lv_textView = (TextView) convertView

                        .findViewById(R.id.lv_textView);

            } else {

                viewHolder = (ViewHolder) convertView.getTag();

            }

 

            viewHolder.lv_textView.setText(list.get(position).title);

    class ViewHolder {

            ImageView lv_imageView;

            TextView lv_textView;
