How to break out of the loop and save data in SurfaceView?

Question

Android

I'm trying to implement a simple game on SurfaceView. There is a class inherited from Thread and a run() method. It is in it that I do drawing and animation. But you need to exit the loop if the variable short gameover = 0, save the data and close the Activity with the SurfaceView. How to organize this? Thanks in advance!
