開始時出現android通知

Question

我正在嘗試創建一個應用程序，在該應用程序中安排一個通知，但是每當我嘗試打開該應用程序時，該通知就會出現.....它會在正確的時間出現，而且在打開應用程序時也會出現。 這是代碼.........

主要活動.java

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Calendar Calendar_Object = Calendar.getInstance();



    Calendar_Object.set(Calendar.HOUR_OF_DAY,16);
    Calendar_Object.set(Calendar.MINUTE,18);
    Calendar_Object.set(Calendar.SECOND,00);

    Intent myIntent = new Intent(MainActivity.this, AlarmReceiver.class);


PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this,
        0, myIntent,0);

AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);



alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, Calendar_Object.getTimeInMillis(),120000,pendingIntent);


}
}

AlarmReceiver.java

 public class AlarmReceiver extends BroadcastReceiver {


@Override

  public void onReceive(Context context, Intent intent) {

  Intent myIntent = new Intent(context, NotificationService.class);
  context.startService(myIntent);
}

} 

NotificationService.java

public class NotificationService extends Service {

private NotificationManager mManager;

@Override
public IBinder onBind(Intent arg0) {

    return null;
}

@Override
public void onCreate() {
    super.onCreate();

}




@Override
public void onStart(Intent intent, int startId) {
    super.onStart(intent, startId);

    mManager = (NotificationManager) this.getApplicationContext()
            .getSystemService(
                    this.getApplicationContext().NOTIFICATION_SERVICE);

    Intent intent1 = new Intent(this.getApplicationContext(), MainActivity.class);

    @SuppressWarnings("deprecation")
    Notification notification = new Notification(R.drawable.images,
            "xys", System.currentTimeMillis());

    intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP
            | Intent.FLAG_ACTIVITY_CLEAR_TOP);


    notification.defaults |= Notification.DEFAULT_SOUND;
    notification.defaults |= Notification.DEFAULT_VIBRATE;


    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
            this.getApplicationContext(), 0, intent1,
            PendingIntent.FLAG_ONE_SHOT);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    notification.setLatestEventInfo(this.getApplicationContext(),
            "xyz", "abcd",
            pendingNotificationIntent);
    notification.flags|= Notification.FLAG_AUTO_CANCEL;

    mManager.notify(0, notification);

    stopSelf();

警報再次觸發，因為在通知后，您將調用MainActivity，在其中再次設置警報。 嘗試在其他活動中設置鬧鍾。 否則，如果在通知后開始活動，則無法設置警報。
