// 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":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false},

{"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","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);

    }
