Xamarin.Forms使非透明叠加层不可单击

Question

I have this XAML

<ContentPage>
     <RelativeLayout>
          <ScrollView />
          <Button />
          <local:ModalActivityIndicator />
     </RelativeLayout>
</ContentPage>

This indicator is relative to its parent and covers it's full width and height.
The indicator has this binding: this.SetBinding (IsVisibleProperty, "IsBusy");
It is showing precisely how I want it, but I can still tap on items in the ScrollView and on the Button . When the indicator shows, the InputTransparent property is set to false .

How can I prevent this?

Answer 1

I found a rather acceptable workaround for this.
If you add a TapGestureRecognizer to the ModalActivityIndicator , all input will be caught by the overlay and no interaction will be transferred to the underlying elements.

GestureRecognizers.Add(new TapGestureRecognizer());
