这是我的适配器类代码：

 public class ChatAdapter extends ArrayAdapter<Chat> {
        private final Context context;
        private final ArrayList<Chat> values;
        ImageLoader imageloader;
        Datamodel dm;

        public ChatAdapter(Context context, ArrayList<Chat> values) {
            super(context, R.layout.list_row_layout_odd, values);
            // TODO Auto-generated constructor stub
            this.context = context;
            this.values = values;
            imageloader = new ImageLoader(context);
        }

        public void addMessage(Chat chat) {
            values.add(chat);
            this.notifyDataSetChanged();
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub

            LayoutInflater inflater = (LayoutInflater) context
