7.                     JSONObject jsonObject=jsonArray.getJSONObject(j);  

8.                    String aidName=jsonObject.getString("aidName");  

9.                    String org=jsonObject.getString("organization");  

10.                    if(jsonArray.size()==1){  

11.                        helpPersonList.add(aidName);  

12.                    }else{  下载 

13.                        helpPersonList.add(aidName+"("+povertys.get(i).getPoorName()+")");  

14.                    }  

15.                    oraList.add(org);  

16.                }  

jsonArray遍历 取出数组中对象
