Android Question Swipe to Close Page

[mohsen programmer]

Hi, I want to implement in B4XPages (B4A) a gesture where, when the user swipes from the left edge to the right, the current page moves dynamically following the finger, revealing the previous page behind it. If the swipe passes a certain distance, the current page should close with an animation; otherwise, it should return to its original position — exactly like the swipe-back effect in Telegram chats.

You can achieve that using
1. sliding layouts (multiple b4a libraries are available each with its own merit)
2. use horizontal CLV with snap feature
3. viewpager (ahviewpager, as viewpager)
4. flowmenu

I don't want to use non-standard or non-optimal methods, and more importantly, the solution must be fully compatible with b4xPages.

You can see how B4XDrawer is implemented with TouchPanelCreator. It is a bit challenging to implement correctly.

Another option is the GestureDetector library: https://www.b4x.com/android/forum/threads/solved-db-phantom.104576/post-655319

Thanks for your answer. I tried the Gesture Detector library but its sample was not implemented based on B4xPages and also it only gave the swipe coordinates. I don't know how to use it to perform exactly like Telegram.
