通知未被解除（Android）

Question

点击操作时通知 setAutoCancel(true) 不起作用

我有一个通知，里面有一个动作。当我点击通知时，它会从列表中删除。但是，当我单击操作时，它成功完成了操作（即拨打电话），但是当我返回通知列表时，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

使用这个标志：

Notification.FLAG_AUTO_CANCEL 在这里面：

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

Answer 2

我今天遇到了这个问题，发现 FLAG_AUTO_CANCEL 和 setAutoCanel(true) 在点击通知时都可以工作， 但不适用于动作点击

很简单，在目标服务或活动中，取消通知

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

或者如果有更多通知

manager.cancel(notificationId);

Answer 3

您已经在两者中创建了两个待处理的意图使用并更改了标志。

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

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

// 改成这一行

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

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

Answer 4

好吧，事实证明这已经是一个已知问题，需要完成额外的代码（通过 id 保持对通知的引用）。不知道为什么 API 不提供此功能，因为这样做似乎很合乎逻辑。但无论如何，

看到这个answer in stackoverflow:

当您在通知管理器上调用 notify 时，您给了它一个 id - 这是您以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，您可以调用：

cancel(int id)

具有相同的 ID。所以，基本上，您需要跟踪 id 或者可能将 id 放入您添加到 PendingIntent 内的 Intent 的 Bundle 中？
