Xamarin Forms: Tap and Double Tap
I am looking at Xamarin Forms capabilities for handling screen interaction at the highest level possible - ideally 1 set of code for both iOS and Andoid. I created a new XF app (Multiplatform -> App in F#, no XAML) and I added this to the default template:
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)
The problem is that the tap still happens as part of the double tap. Is there a way to recognize a tap or a double tap (versus tap and double tap)?
Thanks in advance

That's a know issue. You can use timer to handle such a situation. Wondering If you can avoid double tap with Long press gesture ! If you wish to use timers please go through this thread forums.xamarin.com/discussion/20173/…
