        this.userlist = list;
        inflator = context.getLayoutInflater();
    }

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

        ViewHolder holder = null;
        if (convertView == null) {
            convertView = inflator.inflate(R.layout.custom_list, null);
            holder = new ViewHolder();
            holder.title = (TextView) convertView.findViewById(R.id.tvName);
            holder.date_cr = (TextView) convertView.findViewById(R.id.tvDate);
            holder.img = (ImageView)convertView.findViewById(R.id.ivIcon);
            holder.tokenBtn = (Button)convertView.findViewById(R.id.tokenBtn);
            convertView.setTag(holder);
            convertView.setTag(R.id.tvName, holder.title);
            convertView.setTag(R.id.tvDate, holder.date_cr);
            convertView.setTag(R.id.ivIcon,holder.img);
            convertView.setTag(R.id.tokenBtn,holder.tokenBtn);

        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        String token = userlist.get(position).getToken();

        Log.v("MessageList", "token:" + token);

        token = token.substring(0,token.length()-3);

        holder.title.setText(userlist.get(position).getName()+"("+token+")");

        String type_data =  userlist.get(position).getType().toString();

        if((type_data.equals("text")) || (type_data.equals("photo")))
        {
            Log.v("log", "  if  text photo ");
            holder.date_cr.setText(userlist.get(position).getType()+":Received "+userlist.get(position).getCreated_date());
            holder.tokenBtn.setVisibility(View.VISIBLE);
            list.setItemsCanFocus(true);
        }
        else if(type_data.equals("out"))
        {
            Log.v("log", " else out ");
            holder.date_cr.setText(userlist.get(position).getType()+":Sent "+userlist.get(position).getCreated_date());
            holder.tokenBtn.setVisibility(View.GONE);
        }

        if(type_data.equals("text"))
        {
            Log.v("log", " if text ");
            holder.img.setBackgroundResource(R.drawable.chatmessage);

        }
        else if(type_data.equals("photo"))
        {
            Log.v("log", " ese if photo ");
            holder.img.setBackgroundResource(R.drawable.photomessage);

        }
        else if(type_data.equals("out"))
        {
            Log.v("log", " ese if out ");
            holder.img.setBackgroundResource(R.drawable.outmessafe);
        }


        if(position%2==0)
        {
            convertView.setBackgroundResource(R.drawable.whitebackground);
        }
        else
        {
            convertView.setBackgroundResource(R.drawable.greybackground);

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Log.v("log_tag"," token button clicked");
            }
        });


        return convertView;
    }

     class ViewHolder {

                    int position, long arg3) {
                // TODO Auto-generated method stub

                 msg = userLIstArray.get(position).getMessage();
                  token = userLIstArray.get(position).getToken();
                  type = userLIstArray.get(position).getType();
                  int msgId = userLIstArray.get(position).getMessageid();
                  token = token.substring(0,token.length()-3);
                  int token_value = Integer.parseInt(token) * 1000;   

                if(type.equals("text"))
                {
                    Log.v("log",  " if in text to Display " + msg + " token "+token);
                   Intent i = new Intent(MessagesList.this,DisplayPopupActivity.class);
                   i.putExtra("msg", msg);
                   i.putExtra("token", token);
                   i.putExtra("msgid", msgId);
                   startActivity(i);

                }
