I'm fairly new to Android Development so I'm a little lost. I am trying to make a app with a sliding tab type navigation to get to different screens. 

I've been googling it for like hours and I can't seem to find anything that breaks it down enough for me to understand. From what I read, I would have to use fragments? Right now, I just have my all my screens as separate activities, which I probably would have to change if I'm trying to do this, right?

I haven't really written any code besides messing with the xml so I don't really have much to show.

Anyway, if someone could explain to me how to do this that would be great!
