public class MainActivity extends AppCompatActivity {
    private TextView countdownText;
    private CountDownTimer countDownTimer;
    private long timeLeftInMilliseconds = 3600000; // 1小时

    @Override

        setContentView(R.layout.activity_main);

        countdownText = findViewById(R.id.countdown_text);

        countDownTimer = new CountDownTimer(timeLeftInMilliseconds, 1000) {
            @Override
            public void onTick(long millisUntilFinished) {
                // 更新剩余时间的显示
                int hours = (int) (millisUntilFinished / 3600000);
                int minutes = (int) (millisUntilFinished % 3600000) / 60000;
                int seconds = (int) (millisUntilFinished % 60000) / 1000;
