Android iconitemrenderer可单击对象？
我正在为android和iOS使用Flash Builder 4.5制作一个移动应用程序，并使用itemRenderer和iconitemrenderer类为我的应用程序制作一个选项列表。由于某些原因，我无法使它们可单击，也无法定义单击时要执行的操作。基本上，我的目标是使用FB的“视图”，当点击一个项目时，切换到一个新的视图。以下是我正在使用的代码：Android iconitemrenderer可单击对象？,android,apache-flex,mxml,itemrenderer,navigator,Android,Apache Flex,Mxml,Itemrenderer,Navigator,我正在为android和iOS使用Flash Builder 4.5制作一个移动应用程序，并使用itemRenderer和iconitemrenderer类为我的应用程序制作一个选项列表。由于某些原因，我无法使它们可单击，也无法定义单击时要执行的操作。基本上，我的目标是使用FB的“视图”，当点击一个项目时，切换到一个新的视图。以下是我正在使用的代码： <s:View xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="lib

clickfn=“Projects”此外，您的三个项目没有定义clickFn；因此，他们可能会抛出类似的错误 找到了答案。这里有一个解决方案：

//these if statements were the solution i used. rough, but works well
<![CDATA[
if(event.currentTarget.selectedItem.name == "Projects"){navigator.pushView(Projects);}

if(event.currentTarget.selectedItem.name == "About Us"){navigator.pushView(About);}

//这些if语句就是我使用的解决方案。很粗糙，但效果很好

按照上面的建议，您可以使用这些条件：
navigator.pushView（event.currentTarget.selectedItem.nextView）；
+1，用于提供几乎可运行的代码。嵌入的图像使复制和粘贴运行变得稍微困难；但这比大多数都好。谢谢！它应该在没有图像的情况下运行，您只会得到一条错误消息，并且必须告诉它
