问题 For my Xamarin.Forms app, I am looking for a way to check if a user has the right role/authentication status to access a page. I know Angular has route guards that can be reused for different routes to check for an authentication status. Is there something similar in Xamarin.Forms? 回答1: Here is an example showing how you can control the visibility or navigation to your pages based on the login status of the user. By default Shell will always displays initially the first element defined in

问题 I want to change the status bar color on some views. I found this solution https://github.com/yuv4ik/XFDynamicStatusBarAppearance but it's working only with NavigationPage.

问题 In my xamarin forms project button text are always show in uppercase format. But I am providing upper and lower case letters in xaml. When I build the solution all the letters are changed to uppercase. 回答1: I'm guessing you see this on Android as it is the default for button text and has been since Lollipop. To change this behavior add the following to your styles.xml file which can be found in the Android project under the Resources then values folders <item name="android:textAllCaps">false<

问题 Here's my sample: I need this to be a connection in other apps... Thank you! 回答1: Floating Windows are implemented primarily through the WindowsManager class. Here is a simple sample you could refer to. Create a FloatingService : [Service] class FloatingService : Service,Android.Views.View.IOnTouchListener { WindowManagerLayoutParams layoutParams; IWindowManager windowManager; View floatView; public override void OnCreate() { base.OnCreate(); } [return: GeneratedEnum] public override
