我已经开发了具有从服务器接收通知的功能的应用程序。

I have developed an application which has the functionality of receiving notifications from server.

现在的问题是，当我点击，我收到了一个通知，它的打开我的应用程序本身的新实例。

The problem is, when I click on a notification that I have received, it opens a new instance of my application itself.

此行​​为是确定的，如果我的应用程序是不是在前台的 的，但如果是我尝试打开一个通知，我的应用程序的一个新实例被创建，因此重叠previously打开该应用程序的实例。

This behavior is ok, if my app is not in the foreground, but if it is and I try to open a notification, a new instance of my app is created and thus overlapping the previously opened instance of the app.

我不希望这样的事情发生，所以当我点击的通知，如果我的应用程序是在前台的我必须关闭的，打开一个新的实例。

I don't want this to happen, so when I click on the notification if my app is in the foreground I have to close that and open a new instance.

我应该如何重写通知的单击事件？

How should I override the notification's click event?

您需要做一些神奇的IntentFlags。 尝试不同的标志添加到您的意图。

you need to do some magic with the IntentFlags. try to add different flags to your intent.

notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP| Intent.FLAG_ACTIVITY_NEW_TASK);
