I have been learning android for a short time and would like to implement that functionality, here is an example:
the initial screen is the one on the right and when I touch the cyan-colored bar I move the sub-menu, covering a certain area of the previous view.
I would like to know if you could give me ideas on how to do it, I do not know if doing it with activities or fragments or how to make that displacement effect, Thank you very much.
