如何使用计时器传递到活动并使用跳过按钮取消计时器

private Timer timer;
private TimerTask timerTask;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final TextView countdownTextView = findViewById(R.id.countdownTextView);
    Button skipButton = findViewById(R.id.skipButton);

    timer = new Timer();
    timerTask = new TimerTask() {
        int countdown = 10; // 设置倒计时时间，单位为秒

        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    countdownTextView.setText(String.valueOf(countdown));
                    countdown--;

                    if (countdown < 0) {
                        // 倒计时结束后的操作
                        timer.cancel();
                    }
                }
            });
        }
    };

    timer.schedule(timerTask, 0, 1000); // 每隔1秒执行一次计时器任务

    skipButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            timer.cancel(); // 点击跳过按钮后取消计时器
        }
    });
}

@Override
protected void onDestroy() {
    super.onDestroy();
    timer.cancel();
}
