Java 在Android应用程序的Gallery中显示JSON解析URL中的图像，但出现了畸形异常
我试图解决格式错误的URL异常，但没有成功。在android中搜索了几乎所有与格式错误异常相关的帖子，但问题仍然存在。当我跳过JSON解析并在与imageID[]={“”，}相同的java类中声明imagearray时，它会起作用；当我使用system.Out.println（ImageID[0]）将URL拆分并打印时，我得到了URL；但它不是一个URL 这是我的代码：Java 在Android应用程序的Gallery中显示JSON解析URL中的图像，但出现了畸形异常,java,android,json,eclipse,malformedurlexception,Java,Android,Json,Eclipse,Malformedurlexception,我试图解决格式错误的URL异常，但没有成功。在android中搜索了几乎所有与格式错误异常相关的帖子，但问题仍然存在。当我跳过JSON解析并在与imageID[]={“”，}相同的java类中声明imagearray时，它会起作用；当我使用system.Out.println（ImageID[0]）将URL拆分并打印时，我得到了URL；但它不是一个URL 这是我的代码： public class GalleryActivity extends Activity { private
