Consider using the Android CountDownTimer in any layout you please.

public class Example extends Activity {
    long mMilliseconds = 60000;
    SimpleDateFormat mSimpleDateFormat = new SimpleDateFormat("HH:mm:ss");
    TextView mTextView;

    CountDownTimer mCountDownTimer = new CountDownTimer(mMilliseconds, 1000) {
        @Override
        public void onFinish() {
            mTextView.setText(mSimpleDateFormat.format(0));
        }

        public void onTick(long millisUntilFinished) {
            mTextView.setText(mSimpleDateFormat.format(millisUntilFinished));
        }
    };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mSimpleDateFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
        mTextView = (TextView) findViewById(R.id.text);

        mCountDownTimer.start();
    }
}
