通知通过旧的 Intent Extras [英] Notification passes old Intent Extras

问题描述

我正在通过以下代码在 BroadcastReceiver 中创建通知:

i am creating a notification inside a BroadcastReceiver via this code:

String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(ns);
        int icon = R.drawable.ic_stat_notification;
        CharSequence tickerText = "New Notification";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        long[] vibrate = {0,100,200,200,200,200};
        notification.vibrate = vibrate;
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        CharSequence contentTitle = "Title";
        CharSequence contentText = "Text";
        Intent notificationIntent = new Intent(context, NotificationActivity.class);
        notificationIntent.putExtra(Global.INTENT_EXTRA_FOO_ID, foo_id);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

        int mynotification_id = 1;

        mNotificationManager.notify(mynotification_id, notification);

当我点击通知时，它会打开 NotificationActivity 并且在 Activity 中我可以从 Intent-Bundle(例如 1)中检索 foo_id

When I click on the notification, it opens the NotificationActivity and inside the Activity i can retrieve the foo_id from the Intent-Bundle (e.g. 1)

但是，如果触发另一个通知并且我再次单击它，该活动仍会从 Intent-Bundle 接收旧"值 (1).我尝试使用 clear() 清除捆绑包，但收到了相同的效果.我认为我的代码有问题..

However if another notification is triggered and i click on it again, the activity still receives the "old" value (1) from the Intent-Bundle. I've tried to clear the bundle with clear(), but am receiving the same effect. I think sth is wrong with my code..

推荐答案

您正在为待处理的 Intens 发送相同的请求代码.改变这个:

You are sending the same request code for your pending intens. Change this:

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

致:

PendingIntent contentIntent = PendingIntent.getActivity(context, UNIQUE_INT_PER_CALL, notificationIntent, 0);

如果您发送相同的参数，则不会创建意图.它们被重复使用.

intents are not created if you send the same params. They are reused.
