【中文标题】带有onclick的android imagebuttons上的JSON数组响应【英文标题】：JSon array response on android imagebuttons with onclick 【发布时间】：2016-03-19 14:09:54 【问题描述】：对不起，我的问题只是出现了一行 在我的项目中 image_url1,2,3,4,5 是按意图对另一个活动采取行动，它已经很好地工作了 我无法上传图片，请看下图
┌──────┐┌──────┐┌──────┐┌──────┐┌──────┐
│■■■■■■││ ││ ││ ││ │
│■■■■■■││ ││ ││ ││ │
└──────┘└──────┘└──────┘└──────┘└──────┘
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（或网格视图）上的这些 json 数组响应 我从 WAS 获得一组图像，每行数据都充当按钮 json数组在这里

但我尝试使用此代码，只显示第一张图片，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。请救救我的命
【问题讨论】：
因为你在imageUrlList中只添加了一个image_url。 您只将image_url 添加到列表中
如果你想在 listview 中添加所有 image_url 那么你必须这样做。 imageUrlList.add(image_url); imageUrlList.add(image_url1);imageUrlList.add(image_url2);imageUrlList.add(image_url3);
谢谢你的回复，但这不是我想要的
首先你告诉你得到的不是所有图片的url。如果你得到所有的 url，那么你没有在图像视图中正确设置。
【参考方案1】：
因为您只在列表中添加了一个 image_url。
如果您想在列表中添加所有 url，您必须执行以下操作，
imageUrlList.add(image_url);
imageUrlList.add(image_url1);
imageUrlList.add(image_url2);
imageUrlList.add(image_url3);
imageUrlList.add(image_url4);
imageUrlList.add(image_url5);
imageUrlList.add(image_url6);
但不是这个，
更好的方法是创建所有图片的JSONArray。

感谢您的评论，很抱歉我的问题是错误的，我的问题只是一个 imageurl 和 url1,2,3,4,5 出现我会纠正我的问题【参考方案2】：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);
// String id = jsonObj.getInt("id");
String image_name = jsonObj.getString("image_name");
String image_url = jsonObj.getString("image_url");
String image_url1 = jsonObj.getString("image_url1");
String image_url2 = jsonObj.getString("image_url2");
String image_url3 = jsonObj.getString("image_url3");
String image_url4 = jsonObj.getString("image_url4");
String image_url5 = jsonObj.getString("image_url5");
String image_url6 = jsonObj.getString("image_url6");
String price = jsonObj.getString("price");
imageUrlList.add(image_url);
imageUrlList.add(image_url1);
imageUrlList.add(image_url2);
imageUrlList.add(image_url3);
imageUrlList.add(image_url4);
imageUrlList.add(image_url5);
imageUrlList.add(image_url6);
