Android - What is this component?

Question

I saw a component in an application which shows a small pop-up with a textView when we tap on a button, but the pop-up disappear when we scroll through the page. The pop-up is displayed just under the button, with an arrow in the direction of the button.

I don't know what it is. Please tell me at least the name of the component or a link to an article of android developer's documentation.

@Peterhdd No, it's a type of pop-up that can be displayed everywhere in the screen, that appear when you tap on a button and disappear when you scroll or tap on another place — Tim241, Jul 10 '17 at 06:17

@Peterhdd no, I know fab and toast, and it isn't. It can appear everywhere on the screen, where you tap on the button. It is "linked" to the button — Tim241, Jul 10 '17 at 06:29
@Càphêđen Yes it is! Could you write it as an answer, I would be able to validate it. — Tim241, Jul 10 '17 at 06:31
@Tim241 you can refer to that post. No need a duplication here. ^^ — Cà phê đen, Jul 10 '17 at 06:45
