在我的应用程序通知与通知的用户，如果有什么特别的情况发生：

In my application I notify the user with notifications, if something special happens:

public void triggerNotification(String msg) {
        notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        Intent contentIntent = new Intent(this, ABC.class);
        Notification notification = new Notification(R.drawable.icon, msg, System.currentTimeMillis());
        notification.setLatestEventInfo(this, "ABC", msg, PendingIntent.getActivity(this.getBaseContext(), 0, contentIntent, PendingIntent.FLAG_CANCEL_CURRENT));
        notification.flags = Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(notificationCounter, notification);
        notificationCounter++;
}

如果用户点击通知，所述的onCreate（）方法被调用。但我想，在我的应用程序的具体方法被调用时，或者如果应用程序是不是在前台，这是带回前台。

If the user clicks on the Notification, the onCreate() method is called. But I want that a specific method in my app is called, or if the app is not in the foreground, that it is brought back to the foreground.

我知道有很多的教程解释如何处理通知，但我就是不明白，他们完全，并没有以往任何时候都能够实现类似的事情，我想。

I know there are lots of tutorials that explain how to handle notifications, but I just don't understand them completely and wasn't ever able to implement the things like I'd like to.

推荐答案

要带上你的应用推到前台，如果它已经在运行，你需要在你的意图设置不同的标志：

To bring your app to the foreground if it is running already you need to set different flags on your intent:

contentIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

有关运行的具体方法，你可以只随意图和跨preT在你的应用程序来决定运行哪些方法传递额外的信息。

For running a specific method you could just pass extra information along with the intent and interpret it in your application to decide which method to run.
