直接上代码：



  ResList = DB.select(); //SELECT方法，检索之后返回一个List

                int rowSize = ResList .size();



                if (rowSize != 0) {

                        for (int i = 0; i < 20; i++) {  //固定只输出20行，不够补空行

                            dataTmp = new HashMap<String, String>();

                            if(i < rowSize){

                                dataTmp.put("KENSU1",

                                    sqlRes_List.get(i).get("KENSU1").toString());

                                dataTmp.put("GAK1", sqlRes_List.get(i).get("GAK1")

                                    .toString());

                                dataTmp.put("KENSU2",

                                    sqlRes_List.get(i).get("KENSU2").toString());

                                dataTmp.put("GAK2", sqlRes_List.get(i).get("GAK2")

                                    .toString());

                                dataTmp.put("KENSU3",

                                    sqlRes_List.get(i).get("KENSU3").toString());

                                dataTmp.put("GAK3", sqlRes_List.get(i).get("GAK3")

                                    .toString());

                                dataTmp.put("KENSU4",

                                    sqlRes_List.get(i).get("KENSU4").toString());

                                dataTmp.put("GAK4", sqlRes_List.get(i).get("GAK4")

                                    .toString());

                            }

                            else if (i > rowSize){

                                dataTmp.put("KENSU1","");

                                dataTmp.put("GAK1", "");

                                dataTmp.put("KENSU2","");

                                dataTmp.put("GAK2", "");

                                dataTmp.put("KENSU3","");

                                dataTmp.put("GAK3", "");

                                dataTmp.put("KENSU4","");

                                dataTmp.put("GAK4", "");

                            }
