        }

        public Object getItem(int position) {
            // TODO Auto-generated method stub
            // return product_id1.size();
            return position;

            return position;
        }

        public View getView(final int position, View convertView,
                ViewGroup parent) {
            // TODO Auto-generated method stub
            final ListContent holder;
            View v = convertView;
            if (v == null) {
                v = mInflater.inflate(R.layout.scan_row1, null);
                holder = new ListContent();

                holder.name = (TextView) v.findViewById(R.id.sc_textname);

                holder.name1 = (TextView) v.findViewById(R.id.sc_review);

                holder.ratings = (RatingBar) v.findViewById(R.id.sc_ratingBar1);

                holder.total_rate = (Button) v.findViewById(R.id.button1);

                holder.img_p = (ImageView) v.findViewById(R.id.image_prod);

                // holder.total_rate.setOnClickListener(mOnTitleClickListener1);


                v.setTag(holder);
            } else {

                holder = (ListContent) v.getTag();
            }


            holder.total_rate.setOnClickListener(mOnTitleClickListener3);

            holder.img_p.setOnClickListener(mOnTitleClickListener_image);

            return v;
        }

    static class ListContent {

        ImageView img_p;
        TextView name1;
        TextView name;
        RatingBar ratings;
        Button total_rate;

    }

    public OnClickListener mOnTitleClickListener3 = new OnClickListener() {
        public void onClick(View v) {
            final int position = list_v
                    .getPositionForView((View) v.getParent());

            Log.d("you are click on Ratings","you are click on Ratings");

        }
    };

        public OnClickListener mOnTitleClickListener_image = new OnClickListener() {
