遍历jsonobject

遍历jsonobject

1 entrySet.iterator生成迭代器

2 从迭代器获取Map.Entry的单元对象

3 获取key和value

Map<String,JSONObject> macRssi_id = new HashMap<String, JSONObject>();
        Iterator it = rssi_id.entrySet().iterator();
        while (it.hasNext()){
            Map.Entry<String,JSONObject> entry = (Map.Entry<String,JSONObject>)it.next();
            String key = entry.getKey();

            JSONArray array = rssi_id.getJSONArray(key);
