Question

我正在开发一款允许用户设置时间的应用。在每一次我想设置通知。但是，通知仅在应用程序运行时才有效。

这是我的alarmReceiver

Bundle bu = intent.getExtras();
    int Code = 0;
    if (bu != null) {
        Code = bu.getInt("TIME_CODE");
    }
    Intent MyServiceIntent = new Intent(context, ServiceNotification.class);
    MyServiceIntent.putExtra("TIME_CODE", Code);
    context.startService(MyServiceIntent);

这是我的服务

super.onStart(intent, startId);
    Bundle bu = intent.getExtras();
    int TimeCode = 0;
    if (bu != null) {
        TimeCode = bu.getInt("TIME_CODE");
    }

    NotificationManager mManager;
    mManager = (NotificationManager) this.getApplicationContext()
            .getSystemService(
                    this.getApplicationContext().NOTIFICATION_SERVICE);
    Intent intent1 = new Intent(this.getApplicationContext(),
            MainActivity.class);

    Notification notification = new Notification(R.drawable.ic_launcher,
            "Nuovo messaggio da cura alert", System.currentTimeMillis());
    intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP
            | Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
            this.getApplicationContext(), 0, intent1,
            PendingIntent.FLAG_UPDATE_CURRENT);

    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.setLatestEventInfo(this.getApplicationContext(),
            "Le notifiche funzionano", "It is working....",
            pendingNotificationIntent);
    notification.vibrate = new long[] { 100L, 100L, 200L, 500L };

    mManager.notify(TimeCode, notification);
    try {
        Uri notification_uri = RingtoneManager
                .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Ringtone r = RingtoneManager.getRingtone(getApplicationContext(),
                notification_uri);
        r.play();
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }

这是MainActivity中的一种方法，每次在DB中添加PendingIntent。

for (int i = 0; i < TimeItem.size(); ++i) {
        AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(this, AlarmReceiver.class);
        intent.putExtra("TIME_CODE", i);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, i,
                intent, PendingIntent.FLAG_CANCEL_CURRENT);

        String time = TimeItem.get(i);
        int Position = time.indexOf(":");
        int hour = Integer.parseInt(time.substring(0, Position));
        int min = Integer.parseInt(time.substring(Position + 1));
        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.HOUR_OF_DAY, hour);
        cal.set(Calendar.MINUTE, min);
        cal.set(Calendar.SECOND, 0);
        cal.set(Calendar.MILLISECOND, 0);
        am.set(AlarmManager.RTC, cal.getTimeInMillis(), pendingIntent);
    }

谢谢

Android通知仅在应用运行时有效
