• [转]android中解析后台返回的json字符串


    普通形式的:
    服务器端返回的json数据格式如下:

    {"userbean":{"Uid":"100196","Showname":"u75afu72c2u7684u7334u5b50","Avtar":null,"State":1}}

    分析代码如下:

    // TODO 状态处理 500 200
    int res = ;
    res = httpClient.execute(httpPost).getStatusLine().getStatusCode();
    if (res == 200) {
        /**
         * 当返回码为200时,做处理
         * 得到服务器端返回json数据,并做处理
         * */
        HttpResponse httpResponse = httpClient.execute(httpPost);
        StringBuilder builder = new StringBuilder();
        BufferedReader bufferedReader2 = new BufferedReader(
            new InputStreamReader(httpResponse.getEntity().getContent()));
        String str2 = "";
        for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2
            .readLine()) {
        builder.append(s);
        }
        Log.i("cat", ">>>>>>" + builder.toString());
     
    JSONObject jsonObject = new JSONObject(builder.toString())
        .getJSONObject("userbean");
     
    String Uid;
    String Showname;
    String Avtar;
    String State;
     
    Uid = jsonObject.getString("Uid");
    Showname = jsonObject.getString("Showname");
    Avtar = jsonObject.getString("Avtar");
    State = jsonObject.getString("State");
    带数组形式的:
    服务器端返回的数据格式为:
     
    {"calendar":
    {"calendarlist":
    [
    {"calendar_id":"1705","title":"(u4eb2u5b50)ddssd","category_name":"u9ed8u8ba4u5206u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},
    {"calendar_id":"1706","title":"(u65c5u884c)","category_name":"u9ed8u8ba4u5206u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false}
    ]
    }
    }
     
    分析代码如下:
     
    // TODO 状态处理 500 200
    int res = ;
    res = httpClient.execute(httpPost).getStatusLine().getStatusCode();
    if (res == 200) {
        /**
         * 当返回码为200时,做处理
         * 得到服务器端返回json数据,并做处理
         * */
        HttpResponse httpResponse = httpClient.execute(httpPost);
        StringBuilder builder = new StringBuilder();
        BufferedReader bufferedReader2 = new BufferedReader(
            new InputStreamReader(httpResponse.getEntity().getContent()));
        String str2 = "";
        for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2
            .readLine()) {
        builder.append(s);
        }
        Log.i("cat", ">>>>>>" + builder.toString());
        /**
         * 这里需要分析服务器回传的json格式数据,
         */
        JSONObject jsonObject = new JSONObject(builder.toString())
            .getJSONObject("calendar");
        JSONArray jsonArray = jsonObject.getJSONArray("calendarlist");
        for(int i=;i<jsonArray.length();i++){
        JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i);
        CalendarInfo calendarInfo = new CalendarInfo();
        calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id"));
        calendarInfo.setTitle(jsonObject2.getString("title"));
        calendarInfo.setCategory_name(jsonObject2.getString("category_name"));
        calendarInfo.setShowtime(jsonObject2.getString("showtime"));
        calendarInfo.setEndtime(jsonObject2.getString("endshowtime"));
        calendarInfo.setAllDay(jsonObject2.getBoolean("allDay"));
        calendarInfos.add(calendarInfo);
        }
    总结,普通形式的只需用JSONObject ,带数组形式的需要使用JSONArray 将其变成一个list。
