android - Gooey Animation for Pager Indicator inside Item Decoration

Question

Can some please teach me how to make a gooey pager indicator for on-boarding please?

I really am just curious on how these animations are done.

I am thinking of something like this Here.

Its the example under the . The image might not show it but the circle below combines into one forming a rounded rectangle by a gooey effect before the indicator circle slides to the next circle. After the circle has slide to the correct position, the formed rounded rectangle goes back to its original circular form.

Can someone give me an idea how this could be achieved? Thank you very much in advance.

This is what you need https://github.com/chenupt/SpringIndicator. I've used this once on a project before. The documentation is kind of straight forward.
