Xamarin Gesture

Tap Gesture

With the Tap Gesture, you can make any UI-Element clickable (Images, Buttons, StackLayouts, …):

(1) In code, using the event:

var tapGestureRecognizer = new TapGestureRecognizer();
tapGestureRecognizer.Tapped += (s, e) => {
    // handle the tap
};
image.GestureRecognizers.Add(tapGestureRecognizer);

(2) In code, using ICommand (with MVVM-Pattern, for example):

var tapGestureRecognizer = new TapGestureRecognizer();
tapGestureRecognizer.SetBinding (TapGestureRecognizer.CommandProperty, "TapCommand");
image.GestureRecognizers.Add(tapGestureRecognizer);

(3) Or in Xaml (with event and ICommand, only one is needed):

<Image Source="tapped.jpg">
    <Image.GestureRecognizers>
        <TapGestureRecognizer Tapped="OnTapGestureRecognizerTapped" Command="{Binding TapCommand"} />
  </Image.GestureRecognizers>
</Image>
