问题 Binding a boolean (HasLiked) to Pressed from viewmodel results in error: Failed to create target binding for from HasLiked to Pressed Does it mean that android View.Pressed (and other states) bindings by MvxBind aren't supported by default?

问题 In the MvvmCross v3, CustomerManagement example, the method void RequestClose(IMvxViewModel viewModel) closes the top View . How do you close the View of a ViewModel instead? 回答1: I wouldn't use that ViewModelCloser method - although it could be extended if you want to.

Regards, Dan 回答1: By default the MvvmCross framework doesn't tell you about this event. You'll need to work out some other way of letting the ViewModel know that it needs to do something. How you do this depends on what the actual event is that you are looking for. For example: if the second ViewModel changed some data in an
