Android中的Json解码

Question

我在解码 json 字符串时遇到了困难。下面是我的 json 字符串：

{
    "udeals":"[{\"vName\":\"bussinessname3\",\"vAddress\":\"address3\",\"vState\":\"Kerala\",\"vZip\":\"232\",\"vCountry\":\"Algeria\",\"id\":\"3\",\"dealCategoryID\":\"2\",\"dealCaption\":\"deal3\",\"dealurl\":\"http:\\/\\/192.168.0.8\\/ppppp\\/deals\\/deal3-3\\/\",\"dealImage\":\"http:\\/\\/192.168.0.8\\/ppppp\\/images\\/deals\\/thumb390x256\\/Duizl1.jpg\",\"dealPrice\":\"50.00\",\"dealCost\":\"100.00\",\"dealSave\":-50,\"dealOfferRate\":\"50.00\",\"jsDeadLine\":{\"seconds\":0,\"minutes\":0,\"hours\":0,\"mday\":5,\"wday\":3,\"mon\":1,\"year\":2011,\"yday\":4,\"weekday\":\"Wednesday\",\"month\":\"January\",\"0\":1294165800},\"unlockedStamp\":{\"seconds\":53,\"minutes\":56,\"hours\":18,\"mday\":5,\"wday\":3,\"mon\":1,\"year\":2011,\"yday\":4,\"weekday\":\"Wednesday\",\"month\":\"January\",\"0\":1294234013},\"description\":\"Google URL Shortener at goo.gl is used by Google products to create short URLs that can be easily shared, tweeted, or emailed to friends.\"},{\"vName\":\"bussinessname20010\",\"vAddress\":\"address20010\",\"vState\":\"Kerala\",\"vZip\":\"232\",\"vCountry\":\"Argentina\",\"id\":\"20010\",\"dealCategoryID\":\"2\",\"dealCaption\":\"deal20010\",\"dealurl\":\"http:\\/\\/192.168.0.8\\/ppppp\\/deals\\/deal20010-20010\\/\",\"dealImage\":\"http:\\/\\/192.168.0.8\\/ppppp\\/images\\/deals\\/thumb390x256\\/oCcfTj.jpg\",\"dealPrice\":\"50.00\",\"dealCost\":\"100.00\",\"dealSave\":-50,\"dealOfferRate\":\"50.00\",\"jsDeadLine\":{\"seconds\":0,\"minutes\":0,\"hours\":0,\"mday\":28,\"wday\":2,\"mon\":12,\"year\":2010,\"yday\":361,\"weekday\":\"Tuesday\",\"month\":\"December\",\"0\":1293474600},\"unlockedStamp\":{\"seconds\":53,\"minutes\":56,\"hours\":18,\"mday\":5,\"wday\":3,\"mon\":1,\"year\":2011,\"yday\":4,\"weekday\":\"Wednesday\",\"month\":\"January\",\"0\":1294234013},\"description\":\"this is\"}]"
}

谁能给我一个如何在Android中解析这个的解决方案...

Answer 1

这个json可以用下面的代码解析。

str="<The Json>"
try {
                    JSONObject jObject=new JSONObject(str);
                    JSONArray menuObject = new JSONArray(jObject.getString("udeals"));

                    for (int i = 0; i<menuObject.length(); i++) {
                        System.out.println("length="+menuObject.length());
                        System.out.println("vName="+menuObject.getJSONObject(i)
                                .getString("vName"));
                        System.out.println("vAddress="+menuObject.getJSONObject(i).getString(
                                "vAddress"));
                        System.out.println("vState="+menuObject.getJSONObject(i)
                                .getString("vState"));

                                "vZip"));

                                "dealPrice"));
                        System.out.println("dealCost="+menuObject.getJSONObject(i)
                                .getString("dealCost"));
                        System.out.println("dealSave="+menuObject.getJSONObject(i).getString(
                                "dealSave"));

                        System.out.println("jsDeadLine="+menuObject.getJSONObject(i).getString(
                                "jsDeadLine"));
                        jsDeadLine=menuObject.getJSONObject(i).getString("jsDeadLine");
                        JSONObject deadLine= new JSONObject(jsDeadLine);
                        String seconds = deadLine.getString("seconds");
                        String minutes = deadLine.getString("minutes");

                        System.out.println("unlockedStamp="+menuObject.getJSONObject(i)
                                .getString("unlockedStamp"));

                        unlockedStamp=menuObject.getJSONObject(i).getString("unlockedStamp");

            }




    } catch (Exception e) {
        e.printStackTrace();
    }
    }

JSONObject json = new JSONObject(yourstring);
JSONArray jsa = json.getJSONArray("udeals");
....
