It wraps the Vertical Spinner Wheel part of this Github project. Spin the wheel with a finger - up or down. The spinner is cyclic i.e it acts like a circular buffer.
Posting:
1. B4A project demonstrating the use of the Vertical Spinner Wheel - b4aAndroidSpinnerWheel.zip
2. Zipped files with the required library files (including nineoldandroids) - copy them to your additional library folder. Library files are in AndroidSpinnerWheel.zip
Please note: have added no code in the designer or in the B4A project to position the views - just plonked down and dragged them in the designer. Leaving positioning to those making use of this project.
I will add the Horizontal Spinner Wheel part of the project at some stage...
