Question

我有一个%，应该每天在确切的时间发送application。它可以随时触发，但每当我关闭应用notifications时，它就会出现。

通知类：

notification

MainActivity：

 @Override
public int onStartCommand(Intent intent,int flags, int startId)
{
    super.onStartCommand(intent, flags, startId);
    Context context = getApplicationContext();
    Intent resultIntent = new Intent(getApplicationContext(), Love.class);

    PendingIntent contentIntent = PendingIntent.getActivity(context,
            0, resultIntent,
            PendingIntent.FLAG_CANCEL_CURRENT);
    /* Invoking the default notification service */
    NotificationCompat.Builder  mBuilder = new NotificationCompat.Builder(context);

    mBuilder.setContentTitle("New Message");
    mBuilder.setContentText("You've received new message.");
    mBuilder.setTicker("New Message Alert!");
    mBuilder.setSmallIcon(R.mipmap.ic_launcher);
    mBuilder.setContentIntent(contentIntent);

    android.app.Notification notification = mBuilder.build();
    notification.defaults = notification.DEFAULT_SOUND |
            notification.DEFAULT_VIBRATE;
    notification.flags |= notification.FLAG_AUTO_CANCEL;

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(1, notification);

    return Service.START_STICKY;
}

和BroadcastReceiver：

公共类AlarmReceiver扩展了BroadcastReceiver {

    Calendar c = Calendar.getInstance();
    c.set(Calendar.HOUR_OF_DAY, 10);
    c.set(Calendar.MINUTE, 0);
    c.set(Calendar.SECOND, 0);
    long day = TimeUnit.HOURS.toMillis(24);


    Intent alarmIntent = new Intent(this, AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),day, pendingIntent);

接收器：

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Intent service1 = new Intent(context, Notification.class);
        context.startService(service1);

    }
}

@Override public void onReceive(Context context, Intent intent) { Intent service1 = new Intent(context, Notification.class); context.startService(service1); SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context); Boolean notif = sharedPreferences.getBoolean("notif", true); if (!notif) context.stopService(service1); }必须仅在10:00发送，但它的行为非常奇怪，方法Notification每次都不起作用（如果甚至是假的话）。我想这是带有旗帜的东西，但我仍然不知道我究竟做错了什么。

提前致谢。而且，请不要忘记我的问题，即使它很容易或只是愚蠢。我是新手，只是想知道。

完成后你只需要销毁服务：

NotificationManager notificationManager = (NotificationManager) context
        .getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, notification);
stopSelf()
return Service.START_STICKY;
