我有一个多平台的Xamarin项目，它有一个MainPage（称为OVerviewPage），它有多个FlexLayouts，每个FlexLayouts都绑定到不同的BindableLayout. ItemSource。每个FlexLayouts的BindableLayout.ItemTemplate都是一个ContentView，每个FlexLayouts的格式都类似，但每个FlexLayouts都有一个不同的ViewModel. Model。每个ContentView都有自己的<Frame.GestureRecognizers>TapGestureRocgnizer，调用在代码后面处理的Tapped事件。这些Flexlayouts Package 在ScrollView中，ScrollView也 Package 在RefreshView中。目的是让用户单击其中一个，以便将ContentViews带到详细信息页面。问题是RefreshView在Windows桌面上为UWP编译时会导致冲突。问题是，在向下滚动列表并且用户单击ContentView之后，将调用不同ContentView的TappedEvent处理程序，而不是用户实际单击的那个。实际上，当表单首次加载时，屏幕上可见3个ContentView，当其他人滚动到并驻留在前3个中的一个的位置时，只有前3个中的一个的点击事件会响应单击，这取决于用户单击的屏幕上的位置。当我在xaml中注解RefreshView时，单击按预期工作。我知道RefreshView不是为桌面设备设计的，我试图使用以下命令禁用它：if（Device.Idiom == DeviceIdiom.Desktop）{refreshview.IsEnabled = false}，但这不起作用。仅仅因为它在xaml中被标识这一事实就导致了冲突。有几个注意事项：这个页面是Shell应用程序的主页，任何解决方案都需要考虑到这一点。我也愿意接受大多数解决方案。提前感谢

        formaviewmodel = new FormAViewModel();
        BindingContext = formaviewmodel;
    }
