关于在MAP里面做合计的问题
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", "");
}
if(i%5==0){
// do something..?
}
