View information Stickers on App Android with comand TextView

I downloaded the app from the Android SDK Demo Showroom, I entered my NearableID adhesive. I included in the class Showroom log to read the temperature and** cordinates x, y, z**.

Now I want to see this information on the app with TextView. How can I pass this information from showrooms MainActivity class to class.

Finally, I wonder, what does it mean for example coordinates X = -656.25, Y coordinates: 593.75, Z coordinates: -453,125
