The problem is that you are not using a different view holder for every line, and that when recycling your list item views your holders are shuffled togheter.

You can see this simply adding a final int position field to your holder, where to store the getView position parameter; debugging, you will see what happen.

So, you can't use holders to store your quantity values

Furthermore, you are not using the variable list to store quantity values. This code is working for me:

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

    final ViewHolder holder;
    LayoutInflater inflater = activity.getLayoutInflater();

    if (convertView == null) {

        convertView = inflater.inflate(R.layout.order_custom, null);

        holder = new ViewHolder();

        holder.order = (Button) convertView.findViewById(R.id.order);
        holder.item_name = (TextView) convertView.findViewById(R.id.item_name);
        holder.order_qty = (TextView) convertView.findViewById(R.id.order_count);

        convertView.setTag(holder);

    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    try{
        HashMap map = list.get(position);

        holder.item_name.setText(map.get("name"));
        holder.order_qty.setText(map.get("quantity"));

        //Log.v("Available or not", ""+map.get("available"));


    }catch(Exception e){
        e.printStackTrace();
    }


    holder.order.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) {
            // TODO Auto-generated method stub

            //here am click the button to change order count text value
            int qty = Integer.valueOf(list.get(position).get("quantity"));

            qty++;

            holder.order_qty.setText(""+String.valueOf(qty));
            list.get(position).put("quantity", qty+"");
        }
    });


    return convertView;
}
