目前市场上已经有关于这一主题的几个问题：
There already were several questions on this topic:
- detecting应用程序启动的 在家中或记录
- Determine如果应用程序从启动 主屏幕？
作为主屏幕的部分，据我所知是没有办法来检测。
As of the home screen part, as far as I know there is no way to detect that.
不过，您可以检测从通知图标的活动是否启动：
However, you can detect whether your activity is launched from the notification icon:
在设置您的通知，你把一个额外的到它的 PendingIntent ，说 fromNotification：布尔。
在您的主要活动的的onCreate 方法，你检查的目的的临时演员，如果（有任何和）的 fromNotification 是其中它们与值真，比你知道它已被clikcing通知图标上调用。
When setting up your notification, you put an extra into it's PendingIntent, say fromNotification: boolean.
In your main activity's onCreate method you check the intent's extras, and if (there are any and) the fromNotification is among them with the value true, than you know it has been invoked by clikcing on the notification icon.
