我正在使用来自android docs的内置Json库。我一直在成功解析直到category数组，之后我被困在这里：{＆＃34;数值＆＃34;。我创建了一个物品对象，但之后我无法检索到价值。我应该如何处理这个任何帮助将不胜感激。 P.S不能使用Jackson或Gson解析器，因为其他一切都依赖于我正在使用的当前解析器。
答案 0 :(得分：0)
我不完全确定我理解你的问题，但是你可以使用keys方法获得一个迭代器，它允许你枚举＆＃34;项目中的键。对象
代码看起来与此类似：
JSONObject items = ...;
Iterator itemIter = items.keys();
while (itemIter.hasNext()) {
String key = (String)itemIter.next();
JSONObject item = items.getJSONObject(key);
...
}
编辑：
如果它为您提供Enumeration，则您很可能不会使用org.json。尝试与Iterator交换Enumeration：
JSONObject items = ...;
Enumeration itemEnum = items.keys();
while (itemEnum.hasMoreElements()) {
String key = (String)itemEnum.nextElement();
JSONObject item = items.getJSONObject(key);
...
}
答案 1 :(得分：0)
您可以使用迭代器来解析动态生成的json：以下是我用于项目的代码：
JSONObject responseJsonObject = obj.getJSONArray("items");
int size = responseJsonObject.length();
for(int i = 0;i<size;i++){
Jsonobject temp = responseJsonObject.getItemAtIndex(i);
Iterator keys = temp.keys();
while (keys.hasNext()) {
String curKey = (String) keys.next();
String curValue = responseJsonObject.getString(curKey);
AppData.listCityId.add(curKey);
AppData.listCityName.add(curValue);
// Log.d("key", curKey+ " "+curValue);
}
}
请注意，我只展示了如何解析动态json。
