Android - How to do work or layout on other applications?

Question

I want to show the message to the user. But I want to do it like MusiXMatch. I do not know what the name of the component is.

MusixMatch shows lyrics over other applications until the user closes the application or clicks the hide button. I can explain what I want with 2 images.

Hope I can explain what I want.
