B4A Library CharacterPickerView

It wraps this Github project. Take note of the following:
1. It was created with B4A V5.8 - so not sure if it will run on earlier B4A versions (although I think it should)
2. There are a number of files in the B4A project's /Object/res/..... folders. Once you have downloaded the project, make sure that the files in these folders are set to READ ONLY else they will be deleted when you compile the B4A project.
3. It raises an event in the B4A project when the values of a "Picker" has changed. See the code in the attached B4A project.

Spin them with your finger....

Posting:
1. B4A project to demonstrate the Pickers
2. B4A library files - copy them to your additional library folder

Thank you very much for your continuous contributions which is making B4A better and better .

2. There are a number of files in the B4A project's /Object/res/..... folders. Once you have downloaded the project, make sure that the files in these folders are set to READ ONLY else they will be deleted when you compile the B4A project.

Wouldn't using #AdditionalRes make it easier here ?
