在xamarin.forms中单击包含多个本地通知的推送通知时，它始终返回相同的id

我正在使用xamarin.forms进行申请。我在应用程序中收到多个本地通知。当我点击通知时，它将根据id转到特定页面。我通过PendingEvent发送id。但当我尝试发送多个通知时，PendingEvent只存储最后一个id。请参阅我正在使用的以下代码：

                    manager.CreateNotificationChannel(chan1);

                    notification = new NotificationCompat.Builder(this, PRIMARY_CHANNEL).SetOngoing(true);

                Crashes.TrackError(ex);
            }

        }
    }
}

MainActivity.cs：

protected override void OnNewIntent(Intent intent)
        {
            base.OnNewIntent(intent);
            var title = intent.GetStringExtra("title");
            var tripid = intent.GetStringExtra("tripid");
            if (title != null)
            {
                if (!string.IsNullOrEmpty(tripid))
                {
                    int tripidnotification = Convert.ToInt32(tripid);
                    TruckDetails page = new TruckDetails(tripidnotification);
                    Xamarin.Forms.Application.Current.MainPage.Navigation.PushAsync(page);
                }
            }
        }

当我单击第二个通知时，MainActivity类上的OnNewIntent尚未调用

请帮助我解决此问题。

额外信息将更新为上一次传入意图的额外信息，因此您将获得相同的额外信息。如果您需要为每个通知获取正确的额外信息，有两种方法：

1.定义意图时，还需要区分意图！您可以在intent下添加代码，如下所示：

intent.SetData(Android.Net.Uri.Parse("custom://" + SystemClock.CurrentThreadTimeMillis()));

二,<代码>var pendingIntent=pendingIntent.GetActivity（this，0，intent，PendingIntentFlags.OneShot）更改为：

var pendingIntent = PendingIntent.GetActivity(_ctx,Convert.ToInt32(tripid), resultIntent, PendingIntentFlags.UpdateCurrent);
