问题 What I want to achieve is just to inherit UWP App class not from Windows.UI.Xaml.Application class, but from some base class, inherited from the "standard" one. However, when I do it: namespace MyNamespace { sealed partial class App : MyUwpBaseApplication { public App() { this.InitializeComponent(); } } } and xaml: <local:MyUwpBaseApplication x:Class="MyNamespace.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns

问题 I am using MvxRecyclerView and I want to animate the selected item in the list. How can I get a reference to the selected item view? Should I use TouchDelegate? 回答1: You should be able to get the view reference through the RecyclerAdapter . Implementation Example: Create a custom MvxRecyclerAdapter to deal with your desired animation. public class SelectedAnimatorRecyclerAdapter : MvxRecyclerAdapter { public SelectedAnimatorRecyclerAdapter(IMvxAndroidBindingContext bindingContext) : base

问题 I have a list of items bound to a MvxBindableListView with a MvxItemTemplate. I usually have 4 items in my list bound to my view. Data gets updated and the view displays the new data just fine . Now, I want to add two buttons to this item template. However, relative source binding is not available with MvvmCross. (see image) But I'm having difficulties working out a solution to this. I have tried the ItemClick binding of the list item, but that only gives me 1 possibility of click and I need

问题 I'm using MvvmCross to databind my ViewModel to an Android View layout. From the SimpleBinding example I can see that to bind a value to a property I do this: <EditText android:hint="Subtotal" android:gravity="left" android:inputType="numberDecimal" android:maxLines="1" android:numeric="decimal" local:MvxBind="{'Text':{'Path':'SubTotal','Converter':'Float'}}" /> so Text is bound to the SubTotal property of the ViewModel. But how do I bind to more than one property? In my case I want to bind a

问题 In MvvmCross 4.0.0 the Community SQLite plugin has been replaced with new SQLite-PCL plugin (if I am not mistaken). It works great in my Android application, but when I tried to use it in WPF application I faced problems. When package is installed from nuget there's no default Bootstrap file, therefore Mvx runtime fails to resolve classes like MvxSqliteConnectionFactory . When I add bootstrap code manually I get error like: A first chance exception of type Cirrious.CrossCore.Exceptions

问题 I know there are linking issues with Android and I know about using the LinkerPleaseInclude. However I am not sure what to put into the LinkerPleaseInclude.cs file for the problem I am seeing. I have a view which uses the Visibility converter to use a boolean IsBusy property to determine whether a number of controls should be displayed or not . I am using a ProgressBar, a TextView and an ImageView. I have tried a number of combinations to get the linker issue fixed. When deployed as debug it

问题 What are the steps required to make the two items available in the Add Portable Class Library dialog? 回答1: Please see my answer in Creating a PCL that targets Monodroid In the meantime, there are quite a few blog posts around on how to get PCLs working unofficially - eg.: http://blogs.endjin.com/2013/05/xamarin-platform-setup-gotchas/ http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html 来源： https://stackoverflow.com/questions/16678066/xamarin-support-in-add-portable

问题 I am getting started with MvvmCross in iOS. public class MainView : MvxTabBarViewController { public override void ViewDidLoad() { base.ViewDidLoad(); var vm = (MainViewModel)this.ViewModel; if (vm == null) return; } } Setting a breakpoint to the line where access the ViewModel , shows me, that ViewModel is null. I can workaround this by calling ViewDidLoad() in the constructor. Then, ViewModel is null during the constructor call, but valid in the default ViewDidLoad call. But that looks like

问题 All of a sudden the binding for my TextInputEditText started failing, and it has something to do with the Linker. If I set the linker to "None", everything works as intended. Alot of other bindings im using still works just fine. Stack im getting: Exception thrown during the view binding ArgumentNullException: missing source event info in MvxWeakEventSubscription Parameter name: sourceEventInfo at MvvmCross.Platform.WeakSubscription.MvxWeakEventSubscription 2[TSource,TEventArgs]..ctor

问题 I have a Xamarin Project styled with MvvmCross. There are Subprojects: Core (PCL) ViewModel (PCL) iOS (Executable) If i add an image to my iOS project (Resoureces/Images/test_image.png), then i can load it with this code: UIImage image = UIImage.FromBundle("Images/test_icon.png"); Now, i want to use a new Subproject Controls (iOS Library) This library should load an image. I added an image to Controls (Resoureces/Images/test_image.png) But i can not load this image in Controls proj. My
