B4A Library SplitImageView

The attached project wraps this Github project. The library files are in the /files folder of the B4A project. Copy them to your additional library folder. You will also need to download the images that are used in the B4A project from here (they are too big to zip along with the B4A project). Copy them into the /files folder of the B4A project once you have downloaded and unzipped it.

The pic on the right is set to "auto unveil". The pic on the left is set to "manual unveil". Drag your finger from top right to bottom left or bottom left to top right to unveil more/less of the background image of the pic on the left.

Also posting the Java source code.
