Edit Activity Label

[Fero]

Right now, the label for my Activity has the name of the current Activity. I am fine with that, but I'd also like to add a feature to the top right corner of my Activity, that I can change. Basically I want it to be a text view that will say "Bluetooth: Enabled" or "Disabled" or "Discovering"Is there a way to add a secondary label to an Activity? I feel like in one of my first projects I had it set up like that, but now I can't find it.Thanks
