问题 I have some async calls from Init in view model. The problem is that sometimes async call returns before OnCreate, and the property in UI is not updated.

问题 I want the user to be able to send feedback about my app to an address. Using the email plugin, this is all good, but in the body of the email, I want to pre-populate some information about the app they're running.

问题 1. Binding Lists I wonder how I could bind a ObservableCollection to a Radiogroup: new Section(){ new RootElement("Mandanten", new RadioGroup("mandanten", 2)) { new Section(){ new RadioElement("Kupus", "mandanten"), new RadioElement("Kajmak", "mandanten") } } } as you see here I'm creating 2 Items/Elements manually but I miss something like an "ItemsSource". If its not possible, what recommendation would you give me? To use witch Control (to bind Lists)? 2. CommandBinding As I see theres no

问题 I try to add a fragment to an activity and have already looked at the example from Martijn00. My problem is, that the activity will be displayed but the fragment will not and in debugging mode, the debugger is not running into the fragment's method OnCreateView.

I am sure I do something wrong, but after 6 hours I do give up and ask you guys for help :) Fragment: namespace

问题 I am using MvvmCross v3.5 to build an iOS application. Whenever the application goes into the background I am expecteing SaveState to be called in the view model. However it never gets called. I have tried this both on the simulator and a device. Am I missing something. This works in the Android version of the app, so I think I have set it up correctly. Has anyone else got this issue? Any help would be appreciated. 回答1: I think in Xamarin you need to implement UIApplicationDelegate

问题 I want my android View to trigger a method to create a Toast message whenever a certain property changes in the ViewModel. All the examples I'm finding are binding within the XML. This seems so much simpler yet I can't find any examples. 回答1: You can do this by creating a weak subscription to the viewmodel inside the view and showing the toast when the property changes as follows:- public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Android.OS.Bundle
