JSON解析动态key

工作中后台给我传了带动态的key的json报文的数据，由于没有弄过（key后面需要的）。

{
"data": {
"2016-02": [
{
"account_money": "10.20",
"add_ip": "27.115.75.242",
"add_time": "1454299507",
"affect_money": "3.00",
"back_money": "0.00",
"collect_money": "0.00",
"freeze_money": "0.00",
"id": "330691",
"info": "撤消提现",
"target_uid": "0",
"target_uname": "@网站管理员@",
"type": "撤消提现",
"uid": "18386"
},
{
"account_money": "7.20",
"add_ip": "27.115.75.242",
"add_time": "1454299496",
"affect_money": "-3.00",
"back_money": "0.00",
"collect_money": "0.00",
"freeze_money": "3.00",
"id": "330690",
"info": "提现,默认自动扣减手续费3元",
"target_uid": "0",
"target_uname": "@网站管理员@",
"type": "提现冻结",
"uid": "18386"
}
],
},
"success": "1"
}
```就是上面这样的，没有接触过，查资料，幸亏网上有资料，记录一下。可以通过JSONObject 的keys()方法获得一个迭代器，然后遍历所有的key，keys方法返回一个Iterator对象，它有hasNext方法，来判断是否都遍历完了，用next方法来获取下一个key

<div class="se-preview-section-delimiter"></div>

这里写代码片

while循环是为了得到动态key集合，for循环是为了拿到我项目中需要的数据，处理的不好。好了，谨以此文章记录我遇到的json动态key’问题。

try {
money_record_no_data.setVisibility(View.GONE);
money_record_expandlv.setVisibility(View.VISIBLE);
JSONObject obj = new JSONObject(info);
Iterator<String> keys = obj.keys();
while (keys.hasNext()) {
moneyRecordMess = new ArrayList<MoneyRecordMess>();
String key = keys.next();
recordDates.add(key);
JSONArray data = (JSONArray) obj.get(key);
for (int i = 0; i < data.length(); i++) {
MoneyRecordMess mRecordMess = new MoneyRecordMess();
mRecordMess.setType(data.getJSONObject(i).getString(
"type"));
mRecordMess.setAffect_money(data.getJSONObject(i)
.getString("affect_money"));
mRecordMess.setInfo(data.getJSONObject(i).getString(
"info"));
mRecordMess.setAdd_time(data.getJSONObject(i).getLong(
"add_time"));
// Log.i("type", mRecordMess.getType());
moneyRecordMess.add(mRecordMess);
}
mLists.add(moneyRecordMess);
}
} catch (JSONException e) {
e.printStackTrace();
}
