   new Thread(new Runnable(){
        @Override
        public void run() {
            int counter = 0;
            while (counter < 10000000) {
                counter++;
                final String counterStr = counter.toString();
                tv.post(new Runnable(){
                    @Override
                    public void run() {
                        tv.setText(counterStr);
                    }
