我目前正在从事其他人的项目，因为他们已经离开了公司。我只是在实习，Java不是我的强项。
基本上，该应用程序通过从提要接收信息并将该信息放置在相关位置来工作。
然而，客户要求在已同意的图像上放置图形。
这是为我完成的，因为我无法访问提要。
我想指出，带有图形的提要在 iPhone 应用程序上运行良好。
按下搜索按钮后，此消息会在我的日志 cat 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 AGREED
正如您通过单击链接所看到的那样，将出现图标。
当我单击选项卡搜索属性时，Feed 将开始加载，并且图像将出现在列表视图中。图像会出现，但上面没有让同意的图标，我相信这是因为它将提要中的图像之一作为缩略图，但我需要它来显示图形（我不确定这是否甚至是正确的）。
当我单击查看属性时，图像会消失。
我工作到最后期限，我没有人可以帮助我。请耐心等待我。
以下是我认为您可能需要查看的一些课程。
