This is a custom view to draw dotted, vertical lines.

This custom view shows a progress bar in the foreground of a TextView. Check the Pixplicity Authenticator app for an example.

This view allows draw operations to be executed in a different class. This makes it easier to draw onto a canvas without having to create a custom view for every different use case.

The snippet below is a custom view that enables keyboard like GBoard to enter GIFs and stickers.

This custom view shows a clock-like circular countdown, and can be used as a timer or as a ProgressBar. To use as a timer, create your own handler (or similar) to update the progress automatically.
