This is just a sample of everything that ZXing.Net Mobile has to offer. 8, 13ĭefaultOverlayTopText = "Align the barcode within the frame", Var options = new MobileBarcodeScanningOptions This will allow you to customize the text on the page, but also adjust things such as scanning speed, types, and rotation: The easiest thing to do is to simply set additional properties on the default scanner page and pass it scanning options. There are several ways to customize the scanner pages. On Windows apps you’ll need to ensure that you select the Webcam permission. Global:. (requestCode, permissions, grantResults) Public override void OnRequestPermissionsResult(int requestCode, string permissions, Permission grantResults)

ZXing.Net will handle the runtime permissions in your app automatically by simply adding the following code to your MainActivity.cs: When Android Marshmallow was released it added new runtime permissions when apps need to use features such as the camera or geolocation, similar to iOS. On Android ZXing.Net requires the Camera and Flashlight permission to function, so you’ll need to check these permissions in the project settings or add them to your Android Manifest: You can do this when the OnScanResult event is fired to stop scanning, pop the scanner page, and check the result:ĭevice.BeginInvokeOnMainThread (async () =>Īwait DisplayAlert("Scanned Barcode", result.Text, "OK") Of course, you’ll want to check the results of what was actually being scanned. This will bring up the barcode scanner and put it into scanner mode immediately. First, create a new ZXingScannerPage and then push the page onto the navigation stack: You are able to get barcode scanning in your application with as little as two lines of code. Ensure that you add the package or NuGet to all of your projects to get started. This is a special component and NuGet package that can easily be installed in your Xamarin.Forms projects that adds all the great functionality from the original library, but integrates deeply into Xamarin.Forms by allowing you to customize Xamarin.Forms pages with an embedded scanner. For this post I’m going go focus on the new ZXing.Net package enhanced for Xamarin.Forms. ZXing.Net Mobile is available for your traditional Xamarin applications as both a component and a NuGet package that can be installed in your iOS, Android, Windows, and PCL projects. ZXing.NET Mobile (Zebra crossing) is an open source library that makes scanning barcodes as effortless and painless as possible in your Xamarin and Xamarin.Forms applications.
