Android - json 解析的问题

我有如下的 JSON：

{
        "places": [{
            "name": "Ankola",
            "slug": "ankola",
            "category": "beach",
            "distance": "521",
            "travel_time": "8 hrs, 2 mins",
            "days": "3",
            "latitude": "14.669456",
            "longitude": "74.300952",
            "weather": "Summer 21u00b0-36u00b0C, Winter 12u00b0-35u00b0C",
            "todo": "Baskal gudda, Nadibag, Shedikuli, Keni, Belekeri",
            "about": "Ankola is a small town surrounded by numerous temples. It is in line with Arabian sea. Ankola is famous for its native breed of mango called ishaad and for cashews harvesting.",
           "image": [
                     "Cm5NXlq.jpg",
                     "9OrlQ9C.jpg",
                     "DRWZakh.jpg",
                     "dFKVgXA.jpg",
                     "5WO2nDf.jpg"
                     ]
        }]
}

我知道如何获取关键值- value pairs，但是我不知道如何在json中解析数组，再形成一个字符串数组。
我想实现的是，例如，我在 "image" tag下有5个图像名，我想让它们在一个字符串数组中，如何实现？

解决方案

先把整的弄成一个JsonObject jo = new JsonObject(你获取的内容)；
JsonArray ja = jo.optJsonArray("image");
后面再for循环

解决方案二：

楼上拼错了 =-=
完整的代码：

        try {
            JSONObject jsonObject = new JSONObject(json);
            JSONArray jsonArray = jsonObject.getJSONArray("places");
            for (int i = 0, l = jsonArray.length(); i < l; i++) {
                JSONObject jsonObject2 = jsonArray.getJSONObject(i);
                JSONArray ja = jsonObject2.optJSONArray("image");
                String[] img = new String[5];
                for (int j = 0, k = ja.length(); j < k; j++) {
                    img[i] = ja.get(i).toString();
                    Log.v("", "" + img[i]);
                }
            }
        } catch (JSONException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }
