android - 即使 Activity 停止，计时器也会运行

Question

已从 onCreate 方法启动我的计时器。即使我的 Activity 停止，计时器也会继续运行。怎么可能？

Toast在onTick()方法中显示，Thread是主线程。我想，当 Activity 停止时，主线程将停止。任何人都可以对此进行解释。

CustomCountDownTimer.java

private class CustomCountDownTimer extends CountDownTimer
    {
        public CustomCountDownTimer(long millisInFuture,long countDownInterval)
        {
            super(millisInFuture,countDownInterval);
        }

        @Override
        public void onTick(long millisUntilFinished) {
            // TODO Auto-generated method stub

        long seconds=millisUntilFinished/1000;
        long hours=seconds/(60*60);
        long remainingSeconds=seconds%(60*60);
        long minutes=remainingSeconds/60;
        remainingSeconds=remainingSeconds%60; 

        Toast.makeText(HomeActivity.this, Thread.currentThread().getName()+"", Toast.LENGTH_LONG).show();


        btnStatusMessage.setText(hours+" hr "+minutes+" min "); 

        }

计时器与 Activity 无关。您需要在 Activity 的状态方法之一(onPause/onStop/etc')中停止它。
