编码JSON(android)
我试图从sqlite数据库中的数据解析json 我想要的输出:编码JSON(android),android,json,Android,Json,我试图从sqlite数据库中的数据解析json 我想要的输出: { "report":{ "product":[ { "size": "100" }, { "size": "200" } ] } } 我得到的输出: { "report":{ "product":[ { "size": "200" }, { "size": "200" } ] } } 我的代码: Data = new JSO
{
"report":{
"product":[
{
"size": "100"
},
{
"size": "200"
}
]
}
}
我得到的输出:
{
"report":{
"product":[
{
"size": "200"
},
{
"size": "200"
}
]
}
}
我的代码:
Data = new JSONObject();
Product = new JSONObject();
Report = new JSONObject();
SizeList = controller.distinctSize();
for (HashMap<String, String> map : SizeList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Report.accumulate("product", Product);
Product.put(key, value); //size
}
}
Data.put("report", Report);
try{
Data = new JSONObject();
Report = new JSONObject();
Date date = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
int i=0;
SizeList = controller.distinctSize();
for (HashMap<String, String> map : SizeList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Product = new JSONObject();
Product.put(key, value); //size
ComList = controller.distinctCommodity((String) value);
for (HashMap<String, String> map1 : ComList){
for(Entry<String, String> mapEntry1 : map1.entrySet()){
i++;
String key1 = mapEntry1.getKey();
Object value1 = mapEntry1.getValue();
if(i>1){
Product = new JSONObject();
Report.accumulate("product", Product);
Product.put(key1, value1); //commodity
Product.put(key, value);
}
else{
Report.accumulate("product", Product);
Product.put(key1, value1); //commodity
}
EstabList = controller.establishment( (String) value, (String) value1);
for (HashMap<String, String> map2 : EstabList){
for(Entry<String, String> mapEntry2 : map2.entrySet()){
String key2 = mapEntry2.getKey();
Object value2 = mapEntry2.getValue();
PriceList = controller.price((String) value, (String) value1, (String) value2);
for (HashMap<String, String> map3 : PriceList){
Price = new JSONObject();
Product.put("prices", Price);
for(Entry<String, String> mapEntry3 : map3.entrySet()){
String key3 = mapEntry3.getKey();
Object value3 = mapEntry3.getValue();
Price.put((String) value2, value3); //estabid and price
}
}
}
}
}
}
}
}
Report.accumulate("product",Product);
Report.put("report-date", dateFormat.format(date));
DateList = controller.dates();
for (HashMap<String, String> map : DateList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Report.accumulate(key, value);
}
}
Data.put("report", Report);
但我从代码中得到的是:
{
"report":{
"report-date":"19-03-2013",
"period-start":"18-03-2013",
"period-end":"22-03-2013",
"products":[
{
"commodity":"123456789",
"size":"155g",
"prices":{
"est_id_1":"12.60",
//missing one establishment here
}
},
{
"commodity":"234567890",
"size":"155g",
"prices":{
"est_id_1":"3.5",
}
}
]
}
}
我的代码:
Data = new JSONObject();
Product = new JSONObject();
Report = new JSONObject();
SizeList = controller.distinctSize();
for (HashMap<String, String> map : SizeList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Report.accumulate("product", Product);
Product.put(key, value); //size
}
}
Data.put("report", Report);
try{
Data = new JSONObject();
Report = new JSONObject();
Date date = new Date();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
int i=0;
SizeList = controller.distinctSize();
for (HashMap<String, String> map : SizeList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Product = new JSONObject();
Product.put(key, value); //size
ComList = controller.distinctCommodity((String) value);
for (HashMap<String, String> map1 : ComList){
for(Entry<String, String> mapEntry1 : map1.entrySet()){
i++;
String key1 = mapEntry1.getKey();
Object value1 = mapEntry1.getValue();
if(i>1){
Product = new JSONObject();
Report.accumulate("product", Product);
Product.put(key1, value1); //commodity
Product.put(key, value);
}
else{
Report.accumulate("product", Product);
Product.put(key1, value1); //commodity
}
EstabList = controller.establishment( (String) value, (String) value1);
for (HashMap<String, String> map2 : EstabList){
for(Entry<String, String> mapEntry2 : map2.entrySet()){
String key2 = mapEntry2.getKey();
Object value2 = mapEntry2.getValue();
PriceList = controller.price((String) value, (String) value1, (String) value2);
for (HashMap<String, String> map3 : PriceList){
Price = new JSONObject();
Product.put("prices", Price);
for(Entry<String, String> mapEntry3 : map3.entrySet()){
String key3 = mapEntry3.getKey();
Object value3 = mapEntry3.getValue();
Price.put((String) value2, value3); //estabid and price
}
}
}
}
}
}
}
}
Report.accumulate("product",Product);
Report.put("report-date", dateFormat.format(date));
DateList = controller.dates();
for (HashMap<String, String> map : DateList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Report.accumulate(key, value);
}
}
Data.put("report", Report);
试试看{
数据=新的JSONObject();
报告=新的JSONObject();
日期=新日期();
SimpleDataFormat dateFormat=新SimpleDataFormat(“yyyy-MM-dd”);
int i=0;
SizeList=controller.distinctSize();
for(HashMap映射:SizeList){
对于(条目mapEntry:map.entrySet()){
String key=mapEntry.getKey();
对象值=mapEntry.getValue();
Product=新的JSONObject();
Product.put(键、值);//大小
ComList=控制器.distinctCommodity((字符串)值);
for(HashMap映射1:ComList){
对于(条目mapEntry1:map1.entrySet()){
i++;
字符串key1=mapEntry1.getKey();
对象值1=mapEntry1.getValue();
如果(i>1){
Product=新的JSONObject();
报告.累计(“产品”,产品);
Product.put(键1,值1);//商品
产品。投入(关键、价值);
}
否则{
报告.累计(“产品”,产品);
Product.put(键1,值1);//商品
}
EstabList=控制器。建立((字符串)值,(字符串)值1);
对于(HashMap2:EstabList){
对于(条目mapEntry2:map2.entrySet()){
字符串key2=mapEntry2.getKey();
对象值2=mapEntry2.getValue();
PriceList=controller.price((字符串)值,(字符串)值1,(字符串)值2);
对于(HashMap3:PriceList){
价格=新的JSONObject();
产品卖出价(“价格”,价格);
对于(条目mapEntry3:map3.entrySet()){
字符串key3=mapEntry3.getKey();
对象值3=mapEntry3.getValue();
Price.put((字符串)value2,value3);//estabid和Price
}
}
}
}
}
}
}
}
报告.累计(“产品”,产品);
Report.put(“报告日期”,dateFormat.format(日期));
DateList=controller.dates();
对于(HashMap-map:DateList){
对于(条目mapEntry:map.entrySet()){
String key=mapEntry.getKey();
对象值=mapEntry.getValue();
报告。累计(键、值);
}
}
数据。提交(“报告”,报告);
我应该怎么做?Data=new JSONObject();
Data = new JSONObject();
Report = new JSONObject();
SizeList = controller.distinctSize();
for (HashMap<String, String> map : SizeList){
for(Entry<String, String> mapEntry : map.entrySet()){
String key = mapEntry.getKey();
Object value = mapEntry.getValue();
Product = new JSONObject();
Report.accumulate("product", Product);
Product.put(key, value); //size
}
}
报告=新的JSONObject();
SizeList=controller.distinctSize();
for(HashMap映射:SizeList){
对于(条目mapEntry:map.entrySet()){
String key=mapEntry.getKey();
对象值=mapEntry.getValue();
Product=新的JSONObject();
报告.累计(“产品”,产品);
Product.put(键、值);//大小
}
}
在循环中产品
被重写。每次初始化产品变量都不会在循环中重新初始化。您应该为for循环的每次迭代初始化产品。您好,我可以问您更多关于这个问题的问题吗?已经更新。请查看我的问题。抱歉,我真的不知道如何做。
