android JSONArray JSONObject 字符串轉json數組 遍歷json對象

String json = "{''data'':[{''name'':''Wallace''},{''name'':''Grommit''}]}";   
StringBuffer  marketXml = new StringBuffer();
 
 
 jsonObjSplit = new JSONObject(json );
      JSONArray ja = jsonObjSplit.getJSONArray("data'");
      for (int i = 0; i < ja.length(); i++) {
            JSONObject jo = (JSONObject) ja.get(i);
   

           marketXml.append(jo.get(''name'"));
           System.out.println(marketXml.toString());
     }
-------------------------------------------------------------------------遍歷json 對象
 
    jsonObj = new JSONObject(activeMarketRet);
    
    for (Iterator iter = jsonObj.keys(); iter.hasNext();) { //先遍歷整個 people 對象
        String key = (String)iter.next();
        System.out.println(jsonObj .getString(Key));
   ｝
