Problem with dynamically updating text view in android

I have implemented the logs and they are being displayed on the screen. But even after creating the thread, the logs are not being dynamically updated on the screen. New logs should be appended after one second. While the user stays on the screen, the logs should keep displaying on the screen but it is not happening. The thread that I have created works fine as I have tested it with a count variable. But with logs, it does not seem to work.

Help me out, I am stuck here.
