如何使用ArrayList导航到动态视图

Question

抱歉我的英语不好。 我上了几个小时，但我找不到解决问题的方法。

我想从DataProvider中的arrayList获取视图名称，将我的视图导航到另一个视图。

如何获取点击项目的网址并导航为视图。 感谢..

<s:List id="listMenu" top="0" bottom="0" left="0" right="0" height="100%" width="100%" 
click="navigator.pushView(listMenu.url as View)">
<s:dataProvider>
    <s:ArrayList>
        <fx:Object name="Title1" detail="Detail1" src="@Embed('../media/graphics/credit-card.png')" url="View1" />
        <fx:Object name="Title2 Sorgulama" detail="Detail2" src="@Embed('../media/graphics/IMEI.png')" url="View2" />       
    </s:ArrayList>
</s:dataProvider>
<s:itemRenderer>
    <fx:Component>
        <s:IconItemRenderer labelField="name" messageField="detail" iconField="src" iconWidth="64" iconHeight="64" height="68" />               
    </fx:Component>
</s:itemRenderer>
