问题 I recently found a class called ViewStub that can be used to "lazy-load" a layout-resource. The usage is very straight forward: In the layout file I use: <ViewStub android:id="@+id/content_stub" android:layout_width="match_parent" android:layout_height="match_parent"/> And in my code: var stub = this.FindViewById<ViewStub>(Resource.Id.content_stub); stub.LayoutResource = Resource.Layout.FirstView; stub.Inflate(); However, this way the Bindings won't work! I know, that using mvvmcross I have

I have tried break pointing through the app to make sure this is actually where the hang is happening. I have tried using the exact same code on an ASP.Net Core project to confirm the SignalR connection is working, which it is, I can connect and send commands successfully. I

问题 In our app users can track and submit journeys they have recorded. I need a simple way of creating a task in iOS. I have already created and tested this on Android. It works via: The user selects the journeys they would like to submit. Taps sync and a foreground service is created that syncs the journeys to our API. This service will continue to sync journeys even if the app is put into the background or even closed. So in short how can i achieve this on iOS 9-13? I have already tried

问题 We have an requirement for showing Bing maps view in Xamarin forms app for Android and iOS both.
