On B4J and B4I you need a base panel, only this way the events can be triggered by your other control elements, see the example projects to learn more.

tested on b4i on an iphone 6 (ios 12.4.5) - the demo works great - had it running in 2 minutes. Great work!!!
Thank you, on a real device? Was it smooth? because on my simulator the performance was not the best, but the same code is running well on B4A in debug mode.

Well done Alexander , well done 👍
Thanks! :)

Question - I notice that pressing the next and prev button will increment/decrement the cards. However swiping up or down (or left or right) always increments the cards. If I wanted the card sequence to say increment when I swipe up or swipe right and decrement when I swipe left or swipe down - how would I do that? I see that SwipeStateChanged is called and you can get the swipe action but it seems that the card is incremented before this event is called. Is there a way to get the swipe action and then set the card I'd like to display next?

Well using the bext/previous button the transition was super smooth. Using swipe action, it wasn't as smooth but not bad or anything (release mode is a little faster than debug). The iphone 6 isn't considered latest/greatest and other apps to me feel sluggish so I would attribute this maybe to the phone itself. I have an iphone 10 and will try it on that in the next day or so. Still totally usable though with swipe actions

Then I change it so that the cards are not automatically increased or decreased and the user has to do this himself in the event.

It's not possible. Have you ever seen someone wipe away a card to add another card? Well, I haven't. :)

Hi Alexander very nice library. I need to know how can i put an image view to the swipe card and upload different image to every card. also is it possible to put different controls such as buttons or edittext or labels on each card and how to get the index of those controls so that coding can be done for different controls

ASSwipeCard it's the name of the library unless I'm mistaken.
I've been playing with it and love it.
Awesome job
I want to learn more about about animation, it makes simple things look so much more interesting.

If you only want to diasable the top and bottom events then uncheck the designer properties:

But if you want to disable the swipe gestures to the top or to the bottom, then try to comment out all the code where "downy" occurs
