问题 So for Android when the master page of a master-detail page is shown the master page is covered with a "black dim" view so it is easy to differentiate the two pages with the eye. In iOS the detail page is not dimmed so it is tougher to differentiate the views. Is there a way to overlay the details page with a BoxView or Frame that is "black translucent" so it dims the page in similar fashion to Android. I have tried many different colors and opacities of a box view but they all completely

问题 I am building an app using Xamarin forms PCL. My app will work on android, ios, windows 10 and windows 8.1. I need to implement a tooltip control on tap event for windows os only. I tried tooltip like this- if(Device.OS == TargetPlatform.Windows) { var tapGestureRecognizer1 = new TapGestureRecognizer(); tapGestureRecognizer1.Tapped += TapGestureRecognizer1_Tapped1; icon1.GestureRecognizers.Add(tapGestureRecognizer1); } private void TapGestureRecognizer1_Tapped1(object sender, EventArgs e) {

问题 I'm using an online store for user images uploaded with our App secured by SSL. The upload works all well as I'm using the WebClient with the certificate attached. But when I'm trying to use the Xamarin.Forms.Image component e.g. with the Source set to "https://blabla.com/upload/image123.jpg" the image can't be loaded on Android. On iOS this works as I've got a custom NSUrlProtocol which handles the SSL connection. var image = new Image(); //will use ImageLoaderSourceHandler image.Source =

问题 We have an app that has customizable colors. This makes the orange Android default for selected items in a list view look pretty bad sometimes. We want to change the color of a listview's selected item. I know how to do this in the code behinds (xaml.cs) for our pages and I'm aware you can statically change it in the styles.xml. But because the listview color can change, we could be left with a similar issue with whatever color we pick. Is there a way to access and change the styles.xml

问题 So, What happens to Xamarin.Forms? What is Multi-platform App UI? What is differences between MAUI and Xamarin Where can we generate MAUI projects? 回答1: With .NET 5 Microsoft begins the journey of unifying the .NET platform, bringing .NET Core and Mono/Xamarin together in one base class library (BCL) and toolchain (SDK), more about it here. .NET MAUI as everybody already knows is a name for a new upgraded solution as a Multi-platform App UI framework for building native cross-platform apps

问题 I am building an Android application with Xamarin Forms 3 in Visual Studio 2017 and publishing to Google Play. Google Play offers automated testing (pre-launch report) but it cannot get past my sign-in screen. Google Play has a place to enter the "username resource name", "password resource name", and "sign-in button resource name". I provided the Xamarin x:name for each control ( txtEmail , txtPass , and btnSignIn ), but apparently that is not correct, because the automated tester still can
