Android update TextView in Thread and Runnable

Question

I want to make a simple timer in Android that updates a TextView every second. It simply counts seconds like in Minesweeper.

The problem is when i ignore the tvTime.

Answer 1

As an option use runOnUiThread() to change de views properties in the main thread.

  runOnUiThread(new Runnable() {
        @Override
        public void run() {       
                textView.setText("Stackoverflow is cool!");
        }
    });
