Question

我有一个来自android Http的长字符串，如下所示：

{"movies":[
{"movieId":"fmen71229238","eTitle":"Mission: Impossible - Ghost Protocol","cTitle":"不可能的任務：鬼影行動","imageUrl":"http://test.mobibon.com.tw/MovieGoTest/Pics/pl_fmen7122923814_s.jpg","releaseDate":"2011/12/15","saleType":"0"},
{"movieId":"fstw79905171","eTitle":"Seediq Bale","cTitle":"賽德克．巴萊(上)太陽旗","imageUrl":"http://test.mobibon.com.tw/MovieGoTest/Pics/pl_fstw7990517114_s.jpg","releaseDate":"2011/9/9","saleType":"0"},
{"movieId":"fytw91390391","eTitle":"You Are the Apple of My Eye","cTitle":"那些年，我們一起追的女孩","imageUrl":"http://test.mobibon.com.tw/MovieGoTest/Pics/pl_fytw9139039102_s.jpg","releaseDate":"2011/8/19","saleType":"0"}
]}

字符串是JSON格式，我希望它在不同的数组中排序，并在Listview中显示，所以我使用了像这样的JSON paser

JSONArray result = new JSONArray(retSrc);
        for(int i = 0;i < result.length(); i++)
        {
        JSONObject stock_data = result.getJSONObject(i);
        Log.i("bird","eTitle:"+stock_data.getString("eTitle"));
        }
        } finally {
        }
        }

p.s retSrc是来自网站的长字符串

但是日志

Log.i("bird","eTitle:"+stock_data.getString("eTitle"));

什么都不记录。

我希望它像这样记录：

Answer 1

这是解析它的代码

String jsonData = "{\"movies\":["
                + "{\"movieId\":\"fmen71229238\",\"eTitle\":\"Mission: Impossible - Ghost Protocol\",\"cTitle\":\"??????:????\",\"imageUrl\":\"http://test.mobibon.com.tw/MovieGoTest/Pics/pl_fmen7122923814_s.jpg\",\"releaseDate\":\"2011/12/15\",\"saleType\":\"0\"},"
                + "{\"movieId\":\"fstw79905171\",\"eTitle\":\"Seediq Bale\",\"cTitle\":\"???.??(?)???\",\"imageUrl\":\"http://test.mobibon.com.tw/MovieGoTest/Pics/pl_fstw7990517114_s.jpg\",\"releaseDate\":\"2011/9/9\",\"saleType\":\"0\"},"
                + "{\"movieId\":\"fytw91390391\",\"eTitle\":\"You Are the Apple of My Eye\",\"cTitle\":\"???,????????\",\"imageUrl\":\"http://test.mobibon.com.tw/MovieGoTest/Pics/pl_fytw9139039102_s.jpg\",\"releaseDate\":\"2011/8/19\",\"saleType\":\"0\"}"
                + "]}";
        JSONObject jsonObj = new JSONObject(jsonData);
        JSONArray movieArray = jsonObj.getJSONArray("movies");
        JSONObject movieObj = null;
        for (int i = 0; i < movieArray.length(); i++) {
            movieObj = movieArray.optJSONObject(i);
            if (null != movieObj) {
                String mId = movieObj.optString("movieId");
                String title = movieObj.optString("eTitle");
                String cTitle = movieObj.optString("cTitle");
                String imageUrl = movieObj.optString("imageUrl");
                String releaseDate = movieObj.optString("releaseDate");
                String saleType = movieObj.optString("saleType");
                System.out.println("movieID [" + mId + "] eTitle [" + title
                        + "] cTitle [" + cTitle + "] imgUrl [" + imageUrl
                        + "] relDate [" + releaseDate + "] saleType ["
                        + saleType + "]");
            }

Answer 2

你也可以使用Gson，它为你提供了Json解析的api。只需要创建所需的对象类型即可。

Answer 3

显然，json文件的顶级不是JSONArray而是JSONObject。

使用以下内容：

   JSONObject obj = new JSONOBject(retSrc);
   JSONArray movieArray = obj.getJSONArray("movies");
   //then process the movie as you did
