推荐答案
这是不可能的.ApplicationBar API 的限制性很强，这是 Microsoft 为确保一致性而有意采取的措施.您无法处理来自 ApplicationBar 的任意事件.如果您想要这种行为，则必须构建自己的 UI 来支持它.
This is not possible. The ApplicationBar API is quite restrictive, which is a deliberate move by Microsoft to ensure consistency. You cannot handle arbitrary events from the ApplicationBar. If you want this kind of behaviour, you will have to build your own UI to support it.
值得注意的是，您的用户不会期待应用栏上的长按"(通常称为点击并按住)行为.
It is worth noting that your users will not expect 'long press' (more commonly referred to as tap-and-hold) behaviour on the app-bar.
