推荐答案

其实，我理解了它与我的一个朋友一个小的帮助。需要使用iterator对象。 这里是code中的片段

I actually figured it out with a small help from one of my friend. Needed the use of Iterator object. Here is the snippet of code

JSONObject channels = jobj.getJSONObject(TAG_CHANNELS);
    Iterator<?> keys=channels.keys();
    while( keys.hasNext() )
    {
        String key = (String)keys.next();
        Log.e("Key", key);
        if( channels.get(key) instanceof JSONArray ){
            jsontags.add(key);
        }
    }
