android - 设置通知提醒

Question

嗨，我是 android 新手..我开发了一个程序来设置特定时间的通知但问题是它只显示 2011 年 10 月之前的通知如果我输入 11 月的任何日期，它不会显示任何通知..看起来很奇怪，但真的卡在这里....

主要 Activity ..

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

    Calendar cal = Calendar.getInstance(); // for using this you need to

    cal.set(Calendar.MONTH, 11);
    cal.set(Calendar.YEAR, 2011);
    cal.set(Calendar.DAY_OF_MONTH, 25);
    cal.set(Calendar.HOUR_OF_DAY, 18);
    cal.set(Calendar.MINUTE, 28);

    Intent alarmintent = new Intent(getApplicationContext(),
            AlarmReceiver.class);
    alarmintent.putExtra("title", "Title of our Notification");
    alarmintent.putExtra("note", "Description of our  Notification");


    int HELLO_ID = 1;
    PendingIntent sender = PendingIntent.getBroadcast(
            getApplicationContext(), HELLO_ID, alarmintent,
            PendingIntent.FLAG_UPDATE_CURRENT | 
             Intent.FILL_IN_DATA);

    AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
    am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
}

和警报接收器 Activity ...

public class AlarmReceiver extends BroadcastReceiver {

    private static final String NotificationManager = null;
    private static int NOTIFICATION_ID = 0;

    @Override
    public void onReceive(Context context, Intent intent) {

        (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationManager manger = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.ic_launcher,
                "Combi Note", System.currentTimeMillis());
        PendingIntent contentIntent = PendingIntent.getActivity(context,
                NOTIFICATION_ID, new Intent(context, 
                  AlarmReceiver.class), 0);
        Bundle extras = intent.getExtras();
        String title = extras.getString("title");

        String note = extras.getString("note");
        notification.setLatestEventInfo(context, note, title, contentIntent);
        notification.flags = Notification.FLAG_INSISTENT;
        notification.defaults |= Notification.DEFAULT_SOUND;

    manger.notify(NOTIFICATION_ID, notification);

    }
};

Answer 1

Calendar.set(Calendar.MONTH, month)

需要一个从 0 开始的值。 11 是十二月。
