【问题描述】：

我在从kpbird's example 开发的Android 应用程序中使用了NotificationListenerService。即使应用程序被销毁，该服务也会在后台运行。有没有办法停止此服务并在应用启动时启动它？

【解决方案1】：

NotificationListenerService 不能停止，因为我们启动服务系统后会调用 bindService() 。该服务会保持一个ServiceConnection，然后它不会响应stopService或stopSelf。

作为我的搜索结果，我们也无法从服务实例中删除 ServiceConnection。

【解决方案2】：

在服务内创建一个广播接收器，它扩展了 NotificationListenerService 像这样

public class Block_All_Notification2 extends NotificationListenerService {

boolean check=false;

CancelNotificationReceiver mReceiver = new CancelNotificationReceiver();
public static final String Package_Name = "com.muhaiminurabir.notificationblocker";
@Override
public IBinder onBind(Intent intent) {
    return super.onBind(intent);
}

@Override
public void onNotificationPosted(StatusBarNotification sbn){
    // Implement what you want here
    // Inform the notification manager about dismissal of all notifications.
    Log.d("Msg", "Notification arrived");
    start_blocking();
   /* if (false){
        cancelAllNotifications();
    }*/
    //Block_All_Notification2.this.cancelAllNotifications();
}

@Override
public void onNotificationRemoved(StatusBarNotification sbn){
    // Implement what you want here
    Log.d("Msg", "Notification Removed");
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    String block = intent.getStringExtra("block");
    Log.d("checking service 1",block+"");
    if (block.equals("yes")){
        check=true;
    }else if(block.equals("no")){
        check=false;
    }
    Log.d("checking service 1",check+"");
    return START_STICKY;

}

@Override
public void onCreate() {
    super.onCreate();
    IntentFilter filter = new IntentFilter();
    filter.addAction(Package_Name);
    registerReceiver(mReceiver, filter);
}

@Override
public void onDestroy() {
    super.onDestroy();
    unregisterReceiver(mReceiver);
}

public void start_blocking(){
    Log.d("checking service",check+"");
    if (check==true){
        cancelAllNotifications();
    }
}

class CancelNotificationReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("received service","received");
        String action;
        if (intent != null && intent.getAction() != null) {
            action = intent.getAction();
            if (action.equals(Package_Name)) {
                String block = intent.getStringExtra("block");
                if (TextUtils.equals(block, "no")) {
                    Log.d("checking service 1",block+"");
                    if (block.equals("yes")){
                        check=true;
                        cancelAllNotifications();
                    }else if(block.equals("no")){
                        check=false;
                    }
                    Log.d("checking service 1",check+"");
                } else if (TextUtils.equals(block, "yes")) {
                    Log.d("checking service 1",block+"");
                    if (block.equals("yes")){
                        check=true;
                        cancelAllNotifications();
                    }else if(block.equals("no")){
                        check=false;
                    }
                    Log.d("checking service 1",check+"");
                }
            }
        }
    }

}

}

并在您的活动中添加此代码以与上面创建的服务进行通信

Intent intent = new Intent();
        intent.setAction(Block_All_Notification2.Package_Name);
        intent.putExtra("block", "no");
        context.sendBroadcast(intent);

【解决方案3】：

NotificationListenerService 扩展了 Service，因此您可以通过在 Service 类中调用 stopSelf() 方法来停止服务。
