I noticed the same problem on my app. But it was because I was trying to add (append) the other formats once I created the enumeration list.
With this code, it works:
var formats = new List<ZXing.BarcodeFormat>();
formats.Add(ZXing.BarcodeFormat.QR_CODE);
if (Parameters.Options.AcceptBarcode_Code)
{
formats.Add(ZXing.BarcodeFormat.CODE_39);
formats.Add(ZXing.BarcodeFormat.CODE_93);
formats.Add(ZXing.BarcodeFormat.CODE_128);
formats.Add(ZXing.BarcodeFormat.CODABAR);
}
if (Parameters.Options.AcceptBarcode_Ean)
{
formats.Add(ZXing.BarcodeFormat.EAN_8);
formats.Add(ZXing.BarcodeFormat.EAN_13);
}
if (Parameters.Options.AcceptBarcode_Upc)
{
formats.Add(ZXing.BarcodeFormat.UPC_A);
formats.Add(ZXing.BarcodeFormat.UPC_E);
formats.Add(ZXing.BarcodeFormat.UPC_EAN_EXTENSION);
}
options.PossibleFormats = new List<ZXing.BarcodeFormat>(formats);
Hope this can help others too.
@Adrianotiger it seemed so, thanks :)
Hello I am currently working on a few template projects for my work and wanted to implement a Xaml MVVM solution. I worked a lot with this library but never did CustomOverlay/Xamarin.Forms with it, only with MobileBarcodeReader-class.
I happened to notice that in Forms xaml possible formats aren't working as they should be, by trying binding them through a viewmodel and also adding them after creating viewmodel.
PossibleFormats is just (BarcodeFormat.EAN_13 & BarcodeFormat.UPC_EAN_EXTENSION) and it still reads something like qr_codes (basically everything)
Versions tried: 2.4.1 - current 3.1
On request I can provide link to repository and images to scan, since I don't know if I am doing something wrong
Edit System tested: Android 8.1 (API 27)
