替换JSONObject某个对象的值

有时候我们只想替换JSONObject某个对象的值，不想把所有对象的值都列出来。那就用for循环把所有的值重新赋值一遍。再单独给需要赋值的对象重新赋值

JSONObject itemObject = new JSONObject(sJson);
String labelData = itemObject.getString("TEMPLATE_DATA");
JSONObject labelDetailObject = new JSONObject(labelData);
for (Iterator<String> it = labelDetailObject.keys(); it.hasNext(); ) {
     String key = it.next();
     labelDetailObject.put(key, labelDetailObject.get(key));
}
labelDetailObject.put("LabelSizeWidth",labelWidth);
labelDetailObject.put("LabelSizeHeight",labelHeight);
labelDetailObject.put("LabelGap",labelGap);
for (Iterator<String> it = itemObject.keys(); it.hasNext(); ) {
    String key = it.next();
    itemObject.put(key, itemObject.get(key));
}
itemObject.put("TEMPLATE_DATA",labelDetailObject);

我的JSON格式是

{

"xx": "TEST001",
"xx": "19022001",
"TEMPLATE_DATA": {
   "xx": "TEST001",
   "xxx": "60",
   "xx": "40",
   "xx": "2",
   "xx": "3",
   "xx": [{
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy",
         "xx": "yy"
      }

}

}
