我正在Xamarin编写一个应用程序,为给定的输入创建一个QR代码。
using ZXing.Net.Mobile.Forms;
var writer = new BarcodeWriter
{
Format = BarcodeFormat.QR_CODE,
Options = new EncodingOptions
{
Height = 200,
Width = 600
}
};
var bitmap = writer.Write("Hello Stack Overflow");
我现在如何在表单上显示此条形码?

您应该使用 ZXingBarcodeImageView
using System;
using Xamarin.Forms;
using System.Threading.Tasks;
using ZXing.Net.Mobile.Forms;
public class BarcodePage : ContentPage
{
ZXingBarcodeImageView barcode;
public BarcodePage ()
{
barcode = new ZXingBarcodeImageView {
HorizontalOptions = LayoutOptions.FillAndExpand,
VerticalOptions = LayoutOptions.FillAndExpand,
AutomationId = "zxingBarcodeImageView",
};
barcode.BarcodeFormat = ZXing.BarcodeFormat.QR_CODE;
barcode.BarcodeOptions.Width = 300;
barcode.BarcodeOptions.Height = 300;
barcode.BarcodeOptions.Margin = 10;
barcode.BarcodeValue = "Hello Stack Overflow";
Content = barcode;
}
}
