android - 带有onclick的android图像按钮上的JSON数组响应

对不起，我的问题只出现了一行在我的项目 image_url1,2,3,4,5 中，有意对另一项 Activity 进行操作，并且已经运行良好我无法上传图片，请看下面的图片

┌──────┐┌──────┐┌──────┐┌──────┐┌──────┐
│■■■■■■││      ││      ││      ││      │
│■■■■■■││      ││      ││      ││      │
└──────┘└──────┘└──────┘└──────┘└──────┘
 only first url parsing works another didn't.... 
(first box parsed to image_url, when it clicks image_url1,2,3,4,5 appear)
i want all rows appear, not one row

在我提问之前，我需要多学点英语......

我希望我的应用程序图像按钮(或 GridView )上有这些 json 数组响应我从 WAS 获取一组图像，每行数据充当按钮 json数组在这里

{
"total" : 2,
"row" : [
     {
      "id": "c3asfasfas35sd4a35as5d4a3",
      "image_name": "20150913151562135",
      "image_url": "http://myurl/imagelocation.jpg",
      "flag": null,
      "price": "1200000",
      "image_url1": "http://image_url1/imagelocation.jpg",
      "image_url2": "http://image_url2/imagelocation.jpg",
      "image_url3": "http://image_url3/imagelocation.jpg",
      "image_url4": "http://image_url4/imagelocation.jpg",
      "image_url5": "http://image_url5/imagelocation.jpg",
      "image_url6": "http://image_url6/imagelocation.jpg",
},
{
      "id": "c3asfasfas35sd4a35as5d4a3",
      "image_name": "20150913151562135",
      "image_url": "http://myurl/imagelocation.jpg",
      "flag": null,
      "price": "1200000",
      "image_url1": "http://image_url7/imagelocation.jpg",
      "image_url2": "http://image_url8/imagelocation.jpg",
      "image_url3": "http://image_url9/imagelocation.jpg",
      "image_url4": "http://image_url10/imagelocation.jpg",
      "image_url5": "http://image_url11/imagelocation.jpg",
      "image_url6": "http://image_url12/imagelocation.jpg",

但是我试过这段代码，只有第一张图片显示，另一张没有出现帮帮我!!

仅收到一份数据表(一行)即为成功。我不知道如何接收总行数据....请帮助我。请救我一命

最佳答案

试试这个代码它的工作..

     HttpEntity entity = response.getEntity();
                String resJson = EntityUtils.toString(entity);
                System.out.println("**** = " + resJson);
                jsonStr = resJson;
                JSONTokener jsonParser = new JSONTokener(resJson);
                JSONObject itemList = (JSONObject) jsonParser.nextValue();
                int total = itemList.getInt("total");
                int currentPage = itemList.getInt("currentPage");
                JSONArray jsonObjs = itemList.getJSONArray("rows");
                String demoUrl = "";
                String s = "";
                List<String> imageUrlList = new ArrayList<String>();
                for (int i = 0; i < jsonObjs.length(); i++) {
                    JSONObject jsonObj = jsonObjs.getJSONObject(i);
