Best way to add Buttons in libgdx.

I’m trying to learn libgdx, (so far I like it).

What would be the best way to add buttons to a game.

I kind of know how to add buttons to a Screen, but when i try to do that I can no longer play my game. the buttons take over and i cant click anything else. Am I doing it wrong?

Is the best way to just draw a sprite then detect when i click on that sprite? or is there a better way to add buttons?

I’d like some Ideas or a link to a tutorial. Thanks.
