Now I have the issue that the Highlighted image is on top of the normal image, so that the button is not in Lime, more in something between and the text is getting green. Var image = UIGraphics.GetImageFromCurrentImageContext() Var context = UIGraphics.GetCurrentContext() Ĭontext.SetFillColorWithColor(color.ToCGColor()) Private UIImage ImageWithColor(Color color) Protected override void OnElementChanged(ElementChangedEventArgs e)Ĭontrol.SetBackgroundImage(ImageWithColor(Color.Green), UIControlState.Normal) Ĭontrol.SetBackgroundImage(ImageWithColor(Color.Lime), UIControlState.Highlighted) I tried to implement on iOS the following ButtonRenderer: class OBButtonRenderer : ButtonRenderer The button should be green with white text and on click the button should be in a darker green, but same text color. Now I'm trying to implement the same on iOS and I have one issue. I startet with Android and a custom button, which works fine. I'm currently trying to implement customs controls (Buttons, Labels, etc.) which looks and behave on all plattform similar. Global::(this, bundle) ĭataLayer.Sync(path, sCipherKey, urlText, sDbfile, sAuthScheme, sUsername, sPassword) Path = Path.Combine(fullPath, sqliteFilename) Protected override async void OnCreate(Bundle bundle)įullPath = () // Documents folder I have made a small sample that demonstrates this issue public class AppĬontentPage content = new ContentPage " I done a nuget to get version 1.1.1 before I started so I am not sure if it used to work? Or if what I am doing is supported. I appreciate that I cant really swipe on the map page as the map takes up the full screen but even after I have changed page the swipe to open never comes back. ![]() The menu opens on the main page with a swipe but as soon as I navigate to a page with a map on the swipe to open gesture stops working. I get a button on the navigation header that lets me open the master menu and I can forward navigate into new pages for the different parts of my app. Using Android.App using Android.Content using Android.OS using Android.Runtime using Android.Views using Android.Widget using using using BarcodeQrScanner.Services using SkiaSharp using System using using System.Linq using System.Text using using Xamarin.Forms namespace app design wraps a few pages in a navigation page to load into the details page of a master detail view. The BarcodeQrData structure contains the barcode and QR code results. The IBarcodeQRCodeService interface contains a method for initializing the SDK license and a method for decoding barcode and QR code from a file. In IBarcodeQRCodeService.cs, define an IBarcodeQRCodeService interface and a BarcodeQrData structure. To invoke native platform functionality from shared code, we use the DependencyService class. Get the source code via svn command in terminal:īarcode reader object needs to be created in native code. Therefore, we pick the view example as our codebase and replace the camera2 API with camera API for Android. Native code takes over the whole content page renderingĪlthough Android camera API is out of date, it is still a good choice due to its simplicity.There are some official samples demonstrating how to use the custom renders to bridge the shared code and platform-specific code. Fortunately, it is not necessary to reinvent the wheel. Our goal is to create camera preview interface and invoke Dynamsoft Barcode Reader SDK for decoding barcode and QR code, thus it is inevitable to put lots of effort into platform-specific code. Getting Started with Xamarin.Forms Custom Renderers If you are only interested in how to quickly build a barcode scanner app using Xamarin.Forms, you can skip to the last section. In the end of this article, we will also demonstrate how to use to simplify the development process. This article demonstrates how to scan barcode and QR code from image file and live video stream using Xamarin.Forms Custom Renderers and Dynamsoft Barcode Reader SDK. ![]() NET developers create cross-platform mobile apps for Android and iOS in C#. ![]()
