ZXing QRCode Scanner Xamarin

Question

I tried to implement the package ZXing.Net.Mobile.Forms

this is my xaml:

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         xmlns:zxing="clr-namespace:ZXing.Net.Mobile.Forms;assembly=ZXing.Net.Mobile.Forms"
         Title="{Binding Title}">

<ContentPage.Content>
    <StackLayout>
        <Label x:Name="scanResultText" />
        <zxing:ZXingScannerView 
            OnScanResult="ScanViewOnScanResult"/>
    </StackLayout>
</ContentPage.Content>

and this my xaml.cs :

public partial class QRCodePage : ContentPage
{

    public QRCodePage()
    {
        InitializeComponent();

        BindingContext = new QRCodeViewModel();
    }

    public void ScanViewOnScanResult(Result result)
    {
        Device.BeginInvokeOnMainThread(async () =>
        {
            scanResultText.Text = result.Text;
        });
    }
}

On my device i visualize the fragment but it seems not scanning

Answer 1

Try adding the following code (IsScanning="True") to your xaml:

<StackLayout>
    <Label x:Name="scanResultText" />
    <zxing:ZXingScannerView IsScanning="True"
        OnScanResult="ScanViewOnScanResult"/>
</StackLayout>
