mvvmcross

问题 I'm using MvvmCross v3 and I have a little problem with list in Android. I actually have a Mvx.MvxListView who works well, but I'm working on tablet, and ListView is a little bit inapropriate. So I want to have a control like WrapPannel in XAML to have more than one item in a row. How can I have this kind of control? Thanks 回答1: There are two challenges here: 1. Find or make the control you want The first is really up to you and your UX/design team to do - although people might be able to

问题 Update - Thanks to @Martijn00 and @Plac3Hold3r I have managed to update my app to use the MvxCachingFragmentCompatActivity but it is just not working correctly. I am finding that if I go back sometimes the the ViewModel will be available, but the commands in the view model will be null. Also if I go back and then forward, some of the buttons don't respond. I assume this is the same issue. What I really need to know is what the additional functionality the caching activity gives me, and how to

I was trying to implement last one, using Close

问题 I am working with mono droid, using the mvvmcross framework provided by slodge. However I am having some memory issues. I am disposing bitmaps in the activities ondestroy methods and I am wondering if it is possible to help the GC collecting unused objects of viewmodels. If you try setting the viewmodel in the activity to null it all goes to hell and it is clearly not the right way to go. Do you guys have any suggestions to an approach? Regards 回答1: The mvx framework tries to ensure that the

问题 Love this framework thus far. That said, hit my first roadblock. I have created an MvvmCross-based library (actually a few libraries) that performs login services that will be used across multiple cross-platform applications of the same family. What I can't quite figure out is how to plug these login libraries into my other applications (which will also be using MvvmCross). I want to be able to re-use the same ViewModels and Views across these apps. Assume that I've read and watched a lot of

问题 I have a custom calendar control for which there is an custom viewbinding. In this viewbinding we hook up some events which are not decoupled correct and therefor is the garbage collecting not completed. In the following is our custom view binding. As you can see the event is hooked up in the constructor and decoupled in the OnSelectedDate event is triggered(the user selects an date). Therefore if you choose a date the event is decouple correct and garbage collected but if you just go back,

问题 I'm working on a project in which I can use MapFragment or SupportMapFragment as a custom control. I tried to mix custom control(N-18) and Fraggle(N-26) tutorial but I can't make it work. My Custom Control Class: public class CustomMapView : MvxFragment { public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { var ignored = base.OnCreateView(inflater, container, savedInstanceState); return this.BindingInflate(Resource.Layout
