我目前正在处理别人的项目，因为他们离开了公司。 我只是在实习，java不是我的主题。
基本上，应用程序的工作原理是从提要中接收信息并将信息放在相关位置。
然而，客户要求将图片放在图片上，这些图片已经同意了。
这已经为我完成了，因为我没有访问任何Feed。
我想指出，带有图形的Feed在iPhone应用程序上运行得非常好。
按下搜索按钮后，此消息将在我的日志中打印出来： java.io.FileNotFoundException：http://images.ultrait.me/ImageProcessor.aspx?imageURL=381/Sales/321470/53659_T_ADDRESSES_52050_TN.jpg&Text=LET已同意
从单击链接可以看到，图标出现。
当我点击选项卡搜索属性时，将开始加载Feed，图像将显示在列表视图中。图像会出现，但它上面没有让出约定的图标，我相信这是因为它将图像中的图像作为缩略图放置一个，但我需要它来显示图形（我不确定这是否甚至是正确的。）
当我点击查看属性时，图像消失。
我正在截止日期工作，没有人帮助我。请耐心等待我。
以下是我认为你可能需要看到的一些课程。

答案 0 :(得分：1)
我还没有检查过您的代码，但我想到的第一件事是：您是否检查了应用程序的权限？ 它可能来自那里。 （E.G.：没有互联网许可，找不到文件，因为它没有权限访问它）
编辑：你应该检查（调试或记录）这个“str_imageURLs [i]”是否没有返回奇怪的东西（你应该删除你的URL中的空格）。
然后，如果出现问题，我猜它来自：“FindPropertyActivity.DownloadImage” 你能发贴吗？ 你是否将图像作为输入流并从中形成一个可绘制的（如果它不是在DownloadImage中完成的那样）？
Edit2 ：我在布局中创建了一个只有ImageView的基本应用程序。然后我使用你的“DownloadImage”方法从url获取图像，没有其附加参数（我停在“.jg”）。它在android 4.2上不起作用，因为它要求它是异步的。
我在我的主要活动中添加了这个，然后它起作用了：
ThreadPolicy tp = ThreadPolicy.LAX;
StrictMode.setThreadPolicy(tp);
但很明显，这不是必须要做的事情。
此事既不是您的网址，也不是获取图片的方法。它适用于android 4.2。
你可以用Log.e替换你所有的system.out.println ***（“PutClassNameHere”，“把你的cutom消息放在那里”，throwable）; ？ 这将在logCat中写入错误
