swiftui：自定义按钮在ListView中不起作用

我用Y和N选项创建了一个自定义按钮。（我无法使用“切换”按钮，因为一开始我不需要选择任何选项。

如果将按钮添加到Vstack中，则可以正常工作。按下的选项突出显示，另一个选项变灰。

但是，当将其添加到列表视图中时，单击任何按钮时，看起来都像是单击了整个单元格，并且总是选择了第二个选项。我该如何解决该问题？

导入SwiftUI

struct ContentView: View {

    var body: some View {

        VStack{
            MultiSelectionButtonView()

            Form{
                MultiSelectionButtonView()

                MultiSelectionButtonGroup()
            }
        }
    }
}


struct MultiSelectionButtonView: View {

    var body: some View {
        HStack{
            Text("Question")
            Spacer()
            MultiSelectionButtonGroup()

        }
    }
}

struct MultiSelectionButtonGroup: View {
    @State private var selectedOption : Int = 0

    var body: some View {

        HStack (spacing: 0){
            MultiSelectionButton(tag: 1, text: "Y", selectedOption: $selectedOption)
            MultiSelectionButton(tag: 2, text: "N", selectedOption: $selectedOption)
        }

    }
}

struct MultiSelectionButton: View {

    @State var tag : Int
    @State var text : String
    @Binding var selectedOption : Int


    var shapeSize : CGFloat = CGFloat(35)
    var strokeWidth : CGFloat = CGFloat(0.5)
    var cornerRadius : CGFloat = CGFloat(2)

    var colorSelected : Color = Color.green
    var colorNoSelected : Color = Color.gray.opacity(0.5)
    var colorStroke : Color = Color.gray

    var body: some View {


        Button(action: {
            self.selectedOption = self.tag
        }) {
            ZStack{
                Group {
                    RoundedRectangle(cornerRadius: self.cornerRadius, style: .continuous)
                        //Circle()
                        .fill((self.selectedOption == self.tag) ? colorSelected : colorNoSelected )

                    RoundedRectangle(cornerRadius: self.cornerRadius, style: .continuous)
                        //Circle()
                        .stroke(colorStroke, lineWidth: strokeWidth)
                }
                .frame(width: shapeSize, height: shapeSize)

                Text(text)
                    .font(.subheadline)
                    .fontWeight(.light)
                    .foregroundColor(Color.white)
            }
        }
    }
