android JSON的解析器

我从android Http中获取一个长字符串，如下：

{"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，我想让它在不同的数组中排列，再在一个Listview中显示。所以我使用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 {
        }
        }

retSrc 是网站的长字符串
但是Log是:

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

没有输出任何东西.

我希望log是这样的：

Mission: Impossible - Ghost Protocol Seediq Bale.....
