B4A Library [B4X] [XUI] AS Draggable Bottom Card

This is my 2k'th post on this Forum and i want to share a nice library with you i made some months ago.
It was not easy to create this library, it took many hours of testing and programming to make the user experience as good as possible.

If you want to support me, then you can do this here. Thanks :)

This lib. is only for B4I and B4A.
B4J is not tested and i currently dont want to support it
B4J is now supported


Features
  • cross-platform compatible
  • easy to use
  • use your own header and body layout
  • 2 states - half expanded and full expanded
  • Events
  • and more...
