通知setAutoCancel（true）在点击操作

时不起作用

我收到了包含操作的通知。当我点击通知时，它会从列表中删除。但是，当我单击Action它成功完成Action（即调用）时，但当我返回到通知列表时，它仍然存在。 AlarmReceiver的相关代码：

public class AlarmReceiver extends BroadcastReceiver {
Meeting meeting;

/**
 * Handle received notifications about meetings that are going to start
 */
@Override
public void onReceive(Context context, Intent intent) {

    // Get extras from the notification intent
    Bundle extras = intent.getExtras();
    this.meeting = extras.getParcelable("MeetingParcel");

    // build notification pending intent to go to the details page when click on the body of the notification
    Intent notificationIntent = new Intent(context, MeetingDetails.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    notificationIntent.putExtra("MeetingParcel", meeting);      // send meeting that we received to the MeetingDetails class
    notificationIntent.putExtra("notificationIntent", true);    // flag to know where the details screen is opening from

    PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

    // build intents for the call now button
    Intent phoneCall = Call._callIntent(meeting);
    if (phoneCall != null) {

        PendingIntent phoneCallIntent = PendingIntent.getActivity(context, 0, phoneCall, PendingIntent.FLAG_CANCEL_CURRENT);

        int flags = Notification.FLAG_AUTO_CANCEL;

        // build notification object
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        Notification notification = builder.setContentTitle("Call In")
                .setContentText(intent.getStringExtra("contextText"))
                .setTicker("Call In Notification")
                .setColor(ContextCompat.getColor(context, R.color.colorBluePrimary))
                .setAutoCancel(true)                    // will remove notification from the status bar once is clicked
                .setDefaults(Notification.DEFAULT_ALL)  // Default vibration, default sound, default LED: requires VIBRATE permission
                .setSmallIcon(R.drawable.icon_notifications)
                .setStyle(new NotificationCompat.BigTextStyle()
                        .bigText(meeting.description))
                .addAction(R.drawable.icon_device, "Call Now", phoneCallIntent)
                .setCategory(Notification.CATEGORY_EVENT)   // handle notification as a calendar event
                .setPriority(Notification.PRIORITY_HIGH)    // this will show the notification floating. Priority is high because it is a time sensitive notification
                .setContentIntent(pIntent).build();

        notification.flags = flags;

        // tell the notification manager to notify the user with our custom notification
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notification);
    }
  }
}

Answer 1

我今天遇到了这个问题，发现FLAG_AUTO_CANCEL和setAutoCanel（true）都在点击通知时起作用，但不适用于行动点击

如此简单，在目标服务或行动活动中，取消通知

或者如果有更多通知

NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancelAll();

Answer 2

您已在两者中创建了两个待处理的意图使用，并且也更改了标记。

  PendingIntent pIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), notificationIntent, 0);

  PendingIntent phoneCallIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), phoneCall, PendingIntent.FLAG_UPDATE_CURRENT);

//更改此线

   PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

   PendingIntent phoneCallIntent = PendingIntent.getActivity(context, 0, phoneCall, PendingIntent.FLAG_CANCEL_CURRENT);

Answer 3

使用此标志：

Notification.FLAG_AUTO_CANCEL 在里面：

int flags = Notification.FLAG_AUTO_CANCEL;
Notification notification = builder.build();
        notification.flags = flags;

好的结果证明这已经是一个已知的问题，需要额外的代码才能完成（通过id保持对通知的引用）。不知道为什么API没有提供这个，因为这似乎很合乎逻辑。但无论如何，

请参阅此 answer in stackoverflow：

当您在通知管理器上调用通知时，您为其指定了一个ID - 这是您稍后可以用来访问它的唯一ID（来自通知管理器：

notify(int id, Notification notification)

要取消，请致电：

cancel(int id)

具有相同的ID。所以，基本上，你需要跟踪id或者可能将id放入你添加到PendingIntent里面的Intent的Bundle中？
