I ask for your help. Not so long ago there was a problem with the generation of this very barcode, which was resolved. Here is a link to the discussion: Why is the bar code generated by Zxing displayed in a narrow bar?

Similarly, I try to display the barcode in my application, on the third page of the account - and fail. In the version under the androyd - the bar code is not generated. In the UWP version - everything works fine!

Yes, I can not figure out where to start digging ... :( What could be the problem?

Here is the code for the barcode page:

public Page3() { InitializeComponent(); var qrCode = new ZXingBarcodeImageView() { BarcodeFormat = BarcodeFormat.CODE_39, BarcodeOptions = new QrCodeEncodingOptions() { Height = 100, Width = 350 }, BarcodeValue = Collector.StrihKod, //BarcodeValue = KOD, VerticalOptions = LayoutOptions.CenterAndExpand, HorizontalOptions = LayoutOptions.CenterAndExpand }; Label label01 = new Label() { Text = Collector.StrihKod, BackgroundColor = Color.FromHex("#77d065") }; Label label02 = new Label() { Text = "Where is a barcode ?", BackgroundColor = Color.FromHex("#77d065") }; StackLayout stack = new StackLayout() { Children = { label01, qrCode, label02 } }; this.Content = stack; }

Here is the result of the code

Page3

I would be very happy with any idea! Thank!

Thanks to everyone who tried to help, the answer to the question turned out to find myself ... just by chance in general, like a similar question on the subject of ZXing. I hope that someone will come in handy. Found the solution on Ineta. Link to the original.

I added to the page layout:

 <zxing:ZXingBarcodeImageView x:Name="barcode" BarcodeFormat="CODE_39" HorizontalOptions="Center" VerticalOptions="Center" WidthRequest="300" HeightRequest="150" Margin="5"/>

And in the page code:

 barcode.BarcodeOptions = new ZXing.Common.EncodingOptions() { Height = 100, Width = 350 }; barcode.BarcodeValue = Collector.StrihKod;

And everything turned out!
