Xamarin形式：点击和双击

Question

我正在研究Xamarin Forms的功能，以尽可能高的水平处理屏幕交互-理想情况下，适用于iOS和Andoid的一组代码。我创建了一个新的XF应用程序（F＃中的Multiplatform-> App，没有XAML），并将其添加到默认模板中：

type App() =
    inherit Application()
let stack = StackLayout(VerticalOptions = LayoutOptions.Center)
let label = Label(XAlign = TextAlignment.Center, Text = "Welcome to F# Xamarin.Forms!")

do
    let tapRecognizer = new TapGestureRecognizer()
    let handleTapEvent (sender:Object) (args:EventArgs) =
        label.Text <- "Tapped at " + DateTime.Now.ToString() 
        ()

    let tapEventHandler = new EventHandler(handleTapEvent)
    tapRecognizer.Tapped.AddHandler(tapEventHandler)
    label.GestureRecognizers.Add(tapRecognizer)

    let doubleTapRecognizer = new TapGestureRecognizer()
    doubleTapRecognizer.NumberOfTapsRequired <- 2
    let handleDoubleTapEvent (sender:Object) (args:EventArgs) =
        label.Text <- "Double Tapped at " + DateTime.Now.ToString() 
        ()

    let doubleTapEventHandler = new EventHandler(handleDoubleTapEvent)
    doubleTapRecognizer.Tapped.AddHandler(doubleTapEventHandler)
    label.GestureRecognizers.Add(doubleTapRecognizer)

    stack.Children.Add(label)
    base.MainPage <- ContentPage(Content = stack)

问题是点击仍然是双击的一部分。有没有办法识别点击或双击（相对于点击和双击）？

预先感谢
