Android:如何避免点击通知调用 onCreate() [英] Android: How to avoid that clicking on a Notification calls onCreate()

问题描述

在我的应用程序中，如果发生特殊情况，我会通过通知通知用户:

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，则调用 onCreate() 方法.但我希望我的应用程序中的特定方法被调用，或者如果应用程序不在前台，则将其带回前台.

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.

我知道有很多教程解释了如何处理通知，但我只是不完全理解它们，并且无法实现我想要的东西.

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

要将您的应用程序置于前台，如果它已经在运行，您需要在您的意图上设置不同的标志:

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);

为了运行一个特定的方法，你可以只传递额外的信息和意图，并在你的应用程序中解释它来决定运行哪个方法.

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.
