android解析json小例子

今天學習了一下解析json的知識，把我學習的的一個小例子拿出來和大家分享一下
下面是代碼：
  public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String x;
        JSONObject obj;
        try {

            InputStream is = this.getResources().openRawResource(R.raw.json);  
            byte [] buffer = new byte[is.available()] ;
            is.read(buffer);
            TextView v = new TextView(this);
                    
            String json = new String(buffer,"utf-8");   

            obj = new JSONObject(json);  
                        
            x = obj.getString("名稱");                           
            Log.d("======名稱========",x);
            x = obj.getString("網址");                           
            Log.d("======網址========",x);
            x = obj.getString("摘要");                           
            Log.d("======摘要========",x);
               
            JSONObject obj1 = obj.getJSONObject("網址資料");
            x = obj1.getString("綜合");                           
            Log.d("======綜合========",x);
            x = obj1.getString("層級");                           
            Log.d("======層級========",x);
            x = obj1.getString("數量");                           
            Log.d("======數量========",x);
            
            JSONArray array = obj1.getJSONArray("綜合");   
            obj = array.getJSONObject(0);
            x = obj.getString("綜合1");                           
            Log.d("======綜合1========",x);
            obj = array.getJSONObject(1);
            x = obj.getString("綜合2");                           
            Log.d("======綜合2========",x);
            
            
            JSONStringer s = new JSONStringer();
            Log.d("======================",s.object().key("a").value("aaa").endObject().toString());
            
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

json檔案：
{
   "名稱":"400電話 ",
   "網址":"http://www.my400800.cn ",
   "摘要":"",
   "網址資料":
                  {
                    "數量":"60",
                   "層級":"61",
                   "單位":"62",
                   "綜合":
                               [
                                   {
                                       "綜合1":"100"
                                   },
                                   {
                                       "綜合2":"110"
                                   }                              
                               ]                                 
                 }
}
