Android TableLayout IndexOutOfBoundsException中的ArrayList

我的活动中有一个方法，如果用户向下滚动TableLayout，它应该从webservice添加项。它看起来像：

  private void getOrderList(String page, String perpage) throws JSONException
{

    DatabaseHandler db = new DatabaseHandler(getApplicationContext());
    try {
        DataParsing u = new DataParsing();
        UserFunctions n = new UserFunctions();
        JSONObject k= n.getOrders(page,perpage);

        orders = u.wrapOrders(k);
        Dao<ProcessStatus,Integer> dao = db.getStatusDao();
        Log.i("status",dao.queryForAll().toString());
        QueryBuilder<ProcessStatus,Integer> query = dao.queryBuilder();
        Where where = query.where();
        //query.selectColumns(ProcessStatus.STATUS_TITLE).where().eq(ProcessStatus.STATUS_ID,).toString());
        //PreparedQuery<ProcessStatus, Integer> preparedQuery = ((Object) query).prepareQuery();
        String result = "";
        List<String[]> results = null;
        String res[][] = null;

        try{
            for(Order r : orders)
            {
                 GenericRawResults<String[]> rawResults = dao.queryRaw("select "+ ProcessStatus.STATUS_TITLE +" from process_status where "+ ProcessStatus.STATUS_ID + " = " + r.getProcess_status().getProccessStatusId());
                 results = rawResults.getResults();
                 String[] resultArray = results.get(0); //This will select the first result (the first and maybe only row returned)
                 result = resultArray[0]; //This will select the first field in the result (That should be the ID you need)
                 r.getProcess_status().setProccessStatusTitle(result);
                 Log.i("res",r.toString());
                 forPrint.add(r);
                 Log.i("asd",forPrint.toString());
                 //res = Integer.toString(r.getOrderid());             
             }

        }

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

    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

我应该如何实现这一点

我通过简单的验证解决了这个问题。我的方法appendRows（）如下所示：
