我有一个显示在我的应用程序主屏幕上的 ArrayCollection。我以前有我的代码在选定的索引上推送视图。现在我已经为这个数组集合实现了我的搜索栏。所选索引与搜索索引不匹配。前任。selected index == 0 曾经是 A1c 计算器，如果有人搜索 BMI 计算器，它就会变成 A1c，因为它现在在 selected index == 0 中。

我如何通过在选择 A1c 时总是拉 A1c 来解决这个问题，依此类推，无论它是什么索引。这是代码。

我认为原因是：您不能使用 selectedIndex 来识别视图。

因此，您可以向 ArrayList 的对象添加“viewId”属性：

<fx:Object viewId="A1c" name="A1c Calculator"/>

并且您的列表更改事件处理程序可以使用“viewId”来识别视图：

 if (calcList.selectedItem.viewId == "A1c")//A1c Calculator
 {
   navigator.pushView(views.A1CCalculator);
 }
