android - 单击后如何正确清除所有通知？

Question

我在通知栏上发送了一些通知，我想在单击其中一个通知时清除所有通知。现在我使用Flag一一清除。我知道notificationManager.cancelAll()可以清除所有通知，但我应该把它放在哪里，以便在单击其中一个通知时触发。

 private static void generateNotification(Context context, String message) {
    int icon = R.drawable.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager)
            context.getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);
    String title = context.getString(R.string.app_name); 
    Intent notificationIntent = new Intent(context, MainActivity.class);

    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent =
            PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    notificationManager.notify(msgid, notification);  
    //notificationManager.cancelAll(); //i wan to clear all when the notification is clicked, where should i put this line?
}

我的解决方案是在onResume().

@Override
protected void onResume() {
super.onResume();

// Clear all notification
NotificationManager nMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
nMgr.cancelAll();
}

您应该使用发送广播的待处理意图，然后放置一个广播接收器，它将取消您的所有通知。最好记住所有的通知ID，并一一删除。
