android - JSON数据到android应用程序

Question

我在我的 json 对象中得到了这个部分。但我无法将其作为 java 列表。它给出错误。所以我试着把它当作一个字符串数组。但它和以前一样。那么我应该使用什么来解析此数据以用于我的 Android 应用程序？

cuisine: {
-cuisine_names: [
"All (36)"
"Malaysian/ Singaporean (1)"
"Asian (1)"
"Australian (2)"
"Chinese (1)"
"European (3)"
"Spanish (1)"
"Greek (2)"
"Steak House (1)"
"Indian (1)"
"International (7)"
"Thai (1)"
"Italian (8)"
"Modern Australian (7)"
]
-price_ranges: [
"Any Price"
"$0-15"
"$15-30"
"$30+"
]
-times: [
"Any Time"
"05:30PM"
"06:00PM"
"06:30PM"
"07:00PM"
"07:30PM"
"08:00PM"
"08:30PM"
"09:00PM"
"09:30PM"
"10:00PM"
"10:30PM"
"11:00PM"
"11:30PM"
]
}

提前致谢!

要用 JSONObject 填充列表，您应该使用这样的函数(其中 NewsBSR 是具有一些基本字段的自定义对象):

private ArrayList<NewsBSR> getListObjectsNews(JSONObject objNews)
    {
        ArrayList<NewsBSR> listNews = new ArrayList<NewsBSR>();

        try{
            for (Iterator iterator = objNews.keys(); iterator.hasNext();) 
            {
             String cle = String.valueOf(iterator.next());

             Object objet = objNews.get(String.valueOf(cle));
             Log.v("V", "News: "+cle+ " : "+objet.toString());
             if (cle.equals("results"))
             {
                 JSONArray array = objNews.getJSONArray(cle);
                 for(int i = 0; i < array.length() ; i++)
                 {
                     Object obj = array.get(i);
                     Iterator it = ((JSONObject) obj).keys();
                     NewsBSR news = new NewsBSR();
                     while (it.hasNext())
                     {

                         String k = String.valueOf(it.next());
                         String val = ((JSONObject) obj).getString(k);
                         Log.v("V", "Array content : "+k+ " : "+val);
                         if (k.equals("tt") &&  val.length() > 0)
                         {
                             news.setTitle(val);
                         }
                         if (k.equals("dt") &&  val.length() > 0)
                         {
                            news.setDate(UtilsDate.stringToDate(val));
                         }
                         if (k.equals("num") &&  val.length() > 0)
                         {
                             news.setId(val);
                         }
                     }
                     listNews.add(news);
                 }
             }
            }

        } catch (Exception e) {
            // TODO Auto-generated catch block
             Log.v("V", "Error HOME: "+ e.getMessage());
            e.printStackTrace();
        }


        return (listNews);
    }
