如何正确地清除所有通知一旦点击？ [英] How to properly clear all notification once clicked?

问题描述

我发送通知栏上的几个通知，我想清楚这一切时，点击通知之一。现在我用标志清除一个接一个。我知道 notificationManager.cancelAll（）可以清除所有通知，但我应该在哪里放，这样我可以触发一次被点击通知中的一个。

 私有静态无效generateNotification（上下文的背景下，字符串消息）{
    INT图标= R.drawable.ic_launcher;
    时长= System.currentTimeMillis的（）;
    NotificationManager notificationManager =（NotificationManager）
            context.getSystemService（Context.NOTIFICATION_SERVICE）;
    通知通知=新的通知（图标，消息，时）;
    字符串title = context.getString（R.string.app_name）;
    意图notificationIntent =新意图（背景下，MainActivity.class）;    //设置的意图，因此它不会启动新活动
    notificationIntent.setFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP |
            Intent.FLAG_ACTIVITY_SINGLE_TOP）;
    的PendingIntent意图=
            PendingIntent.getActivity（上下文，0，notificationIntent，0）;
    notification.setLatestEventInfo（上下文，标题，邮件，意图）;
    notification.flags | = Notification.FLAG_AUTO_CANCEL;    notificationManager.notify（MSGID，通知）;
    //notificationManager.cancelAll（）; // i湾被点击的通知时，清除所有，在那里我应该把这一行？
}
 

解决方案

我的解决办法是在 onResume称之为（）。

  @覆盖
保护无效onResume（）{
super.onResume（）;//清除所有通知
NotificationManager nMgr =（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）;
nMgr.cancelAll（）;
}
 

I send a few notification on the notification bar, i wanted to clear all of it when one of the notification is clicked. For now I clear one by one by using Flag. I know notificationManager.cancelAll() could clear all the notification but where should i put so that i can trigger once one of the notification is clicked.

 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?
}

解决方案

My solution is to call it at onResume().

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

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