I do want to create a plugin which does implement something like a notification-service.
So what I'm doing at the moment is something like this:
var activity = Mvx.Resolve<IMvxAndroidCurrentTopActivity>().Activity;
var builder = new NotificationCompat.Builder(activity.ApplicationContext)
.SetContentTitle(title)
.SetSmallIcon(Resource.Drawable.Icon)
.SetContentText(message);
var notificationManager = (NotificationManager)activity.ApplicationContext.GetSystemService(Context.NotificationService);
notificationManager.Notify(0, builder.Build());
This works fine and does show the notification as it should show. Next step is, that I want to navigate from the notification to my activity. Which means in MvvmCross I do want to navigate to my ViewModel.
But how do I now pack the ShowViewModel<...>()-Command into this notification? Is this even possible?
On native android I would create a PendingIntent which does point to my Activity I want to show.
Any idea? Hint? Tip? :-)
The default MvvmCross presenter on Android uses Intent
s for navigation. These are generated by the method Intent GetIntentFor(MvxViewModelRequest request)
in the IMvxAndroidViewModelRequestTranslator
interface.
By default this is implemented within: MvxAndroidViewsContainer.cs#L117
public virtual Intent GetIntentFor(MvxViewModelRequest request)
{
var viewType = GetViewType(request.ViewModelType);
if (viewType == null)
{
throw new MvxException("View Type not found for " + request.ViewModelType);
}
var converter = Mvx.Resolve<IMvxNavigationSerializer>();
var requestText = converter.Serializer.SerializeObject(request);
var intent = new Intent(_applicationContext, viewType);
intent.PutExtra(ExtrasKey, requestText);
AdjustIntentForPresentation(intent, request);
intent.AddFlags(ActivityFlags.NewTask);
return intent;
}
If you need to generate Intent
s for other purposes (e.g. in order to then go on and generate PendingIntent
s) then you can Resolve
and call this interface yourself.
var request = MvxViewModelRequest<MyViewModel>.GetDefaultRequest();
request.PresentationValues = new Dictionary<string, string>() {
{ "life", "42" }
};
var translator = Mvx.Resolve<IMvxAndroidViewModelRequestTranslator>();
var intent = translator.GetIntentFor(request);
var pending = PendingIntent.GetActivity (context, 0, intent, 0);
For further information on generating MvxViewModelRequest
objects, see also the overloaded ShowViewModel
methods in MvxNavigatingObject.cs
