我在 Flash 中遇到 CalloutButtons 和容器的问题。我已经成功创建了一个标注按钮，它显示了一个可滚动的项目列表。选择一个项目后，相应的图像应显示在主视图中。

但由于某种原因，似乎出现了 2 个标注 - 当我向下滚动菜单时，一个实例关闭并传递数据（这是以前存储的数据，因为这次还没有选择数据）。 ...当我确实选择了一个项目时，列表会关闭，但不会再次调用 closeHandler。

问题似乎是当单击 calloutButton 时，Flex 会自动创建一个标注容器。我怎样才能禁用它？

或者换成我的...

谢谢

编辑 - 这是我的代码：

PrimaryCallout.mxml

感谢您的代码。您的两个 Callout 实例的原因是您使用了CalloutButton一个单独的Callout. 鉴于CalloutButton创建自己的实例，Callout你最终会同时拥有CalloutButton's defaultCallout和你自己创建的实例。

您需要更改的是使用您PrimaryCallout的通用按钮（这将需要您自己处理打开/关闭操作）或使用CalloutButton's 默认值Callout。
