如何停止另一个类的 NotificationService？

Question

我有NotificationService 类扩展Service 并启动服务whit 方法，但我不知道如何停止当前服务，我阅读了一些指南和示例，但使用stopService() 方法我不能停止我的服务。这是我班的代码，我怎么能停下来？

public class NotificationService extends Service {

private final long TIME_WAKE_UP = 6000;//60 * 60 * 1000;
private long timeStart;
private Esercizio es;

@Override
public void onCreate() {
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
    Notification mNt = mBuilder.build();
    startForeground(2, mNt);
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    timeStart = intent.getExtras().getLong("timeStart");
    es = (Esercizio) intent.getExtras().get("esercizio");

    while(System.currentTimeMillis() < timeStart + TIME_WAKE_UP);

    atWork();

    stopForeground(true);
    stopSelf();

    return START_STICKY;
}

private void atWork() {
    Intent intent = new Intent(this, TransitionArchive.class);
    Bundle bundle = new Bundle();
    bundle.putString("notificationService","");
    bundle.putString("KEY_EXCERSIZE",es.getNameEx());
    intent.putExtras(bundle);

        NotificationCompat.Builder mBuilderOffline =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.logo_app_android)
                        .setContentTitle(es.getNameEx())
                        .setContentText("C'è un nuovo contenuto per te!")
                        .setAutoCancel(true)
                        .setPriority(Notification.PRIORITY_MAX)
                        .setVisibility(NotificationCompat.VISIBILITY_PUBLIC);

        PendingIntent pendingIntent = PendingIntent.getActivity(this,
                1,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilderOffline.setContentIntent(pendingIntent);

        //PendingIntent call the receive class

        Notification note = mBuilderOffline.build();
        note.defaults |= Notification.DEFAULT_SOUND;
        note.defaults |= Notification.DEFAULT_VIBRATE;

        NotificationManager mNotificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(1, note);
}

public static void startNotificationService(Context mContext, Esercizio es) {
    Intent mIntent = new Intent(mContext, NotificationService.class);
    mIntent.putExtra("esercizio", es);
    mIntent.putExtra("timeStart", System.currentTimeMillis());
    startWakefulService(mContext, mIntent);
}

@Override
@Nullable
public IBinder onBind(Intent intent) {
    return null;
}

Answer 1

这样试试

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    timeStart = intent.getExtras().getLong("timeStart");
    es = (Esercizio) intent.getExtras().get("esercizio");

    while(System.currentTimeMillis() < timeStart + TIME_WAKE_UP);

    atWork();

    stopForeground(true);
    stopSelf();

    return START_NOT_STICKY;
}

Answer 2

这可能不是最好的方法，但我使用公共静态变量作为 IntentService 的标志。如果设置了标志，则执行任何必要的清理、停止线程、退出循环，并让它自然地流向 stopSelf() 和 stopForeground()（你已经拥有）。
