    }

private boolean isFirst = true;
    private TextView tvTime;

    private Handler handler = new Handler() {
        @Override

            if (msg.what == 0) {
                dt = dt - 1000;
                SimpleDateFormat sd = new SimpleDateFormat("HH:mm:ss");
                tvTime.setText(sd.format(new Date(dt)));

                handler.removeMessages(0);
                handler.sendEmptyMessageDelayed(0, 1000);
                if (dt == 0) {
                    handler.removeMessages(0);
                }
            }

        }
    };
