Pinch-zoom on an Image inside CarouselView throws exception #563

Open shnaz opened 4 years ago

shnaz commented 4 years ago

Hi, we are using the CarouselView as a gallery-page in our app, where images can be zoomed by pinch-gesture. We have been experiencing some crashes due to "pointer out of index"-exceptions thrown in the CustomViewPager.OnInterceptTouchEvent(..).

I have googled the issue and it seems that it is a general framework bug in ViewPager and DrawerLayout, the workaround is to try-catch the super.onInterceptTouchEvent(event).

Have you heard about this before?

Btw, thanks for the great work, we have been using this CarouselView many years now!
