Question

基于Android开发者网站上的文档，onNotificationRemoved(with reason)方法可让您了解取消通知的原因，例如用户清除了所有通知，或仅清除了您的通知等。

我已经测试了其他一些回调，即onNotificationPosted和onNotificationRemoved without reason，它们已成功调用。

以下是我创建的NotificationListenerService的实现：

package com.solo.notificationlistener;

import android.app.Notification;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;


public class MyNotificationListenerService extends NotificationListenerService {

@Override
public void onNotificationPosted(StatusBarNotification sbn) {
    super.onNotificationPosted(sbn);

    if (sbn.getPackageName().equals(getBaseContext().getPackageName())) {
        Notification notification = sbn.getNotification();
        String notificationText = notification.extras.getString(Notification.EXTRA_TEXT);
        Log.d(getClass().getSimpleName(),
                String.format("Just posted notification: %s", notificationText));
    }
}

@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
    super.onNotificationRemoved(sbn);

    if (sbn.getPackageName().equals(getBaseContext().getPackageName())) {
        Notification notification = sbn.getNotification();
        String notificationText = notification.extras.getString(Notification.EXTRA_TEXT);

        Log.d(getClass().getSimpleName(),
                String.format("Dismissed notification: %s", notificationText));
    }
}

@Override
public void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap, int reason) {
    super.onNotificationRemoved(sbn, rankingMap, reason);
    Log.d(getClass().getSimpleName(), "Dismissing with a reason");

    if (sbn.getPackageName().equals(getBaseContext().getPackageName())) {
        Notification notification = sbn.getNotification();
        String notificationText = notification.extras.getString(Notification.EXTRA_TEXT);
        Log.d(getClass().getSimpleName(),
                String.format("Dismissed notification: %s\n Reason: %s",
                        notificationText,
                        (reason == NotificationListenerService.REASON_CANCEL) ?
                                "Specifically cancelled my app" :
                                "Cancelled all perhaps"
                ));
    }
}

}

关于为什么会发生这种行为的任何想法？非常感谢您的协助

OnNotification删除原因是API> = 26 难道就是因为这个原因，该方法没有触发？

系统未调用Android NotificationListenerService＃onNotificationRemoved（...，int原因）
