Little Help in Android Studio - Java

Hi. I have an Android Studio Project, which you can find Attached to this Project, which has a couple of Classes. When you run the App, there are just Two Buttons and a Toast. That Toast gets refreshed kind of like 10 Times a Second (its a String taken from a 'Refreshing' Int called "fr"). I need the following to be done with this Little App. To send the Refreshing Int "fr" to some Activity with the only layout there is setted as the ContentView, and say: If "fr" is less than 120, then set in a Refreshing TextView the Word "One", and if "fr" gets refreshed exceeding the 120, then that the TextView would set the Word "Two", visible to the User. That's all. If you need to make the TextView to refresh, I can already give you a simple method which schedules it to be refreshed twenty times a second. I'll expect your proposals.
