public String getJson(){ String jsonString = "{\"FLAG\":\"flag\",\"MESSAGE\":\"SUCCESS\",\"name\":[{\"name\":\"jack\"},{\"name\":\"lucy\"}]}";//json字符串 try { JSONObject result = new JSONObject(jsonstring);//转换为JSONObject int num = result.length(); JSONArray nameList = result.getJSONArray("name");//获取JSONArray int length = nameList.length(); String aa = ""; for(int i = 0; i < length; i++){//遍历JSONArray Log.d("debugTest",Integer.toString(i)); JSONObject oj = nameList.getJSONObject(i); aa = aa + oj.getString("name")+"|"; } Iterator<?> it = result.keys(); String aa2 = ""; String bb2 = null; while(it.hasNext()){//遍历JSONObject bb2 = (String) it.next().toString(); aa2 = aa2 + result.getString(bb2); } return aa; } catch (JSONException e) { throw new RuntimeException(e); } }
