After clicking on notification, get the information in notification

After clicking on notification, it is often necessary to present the information in the notification on the interface.

At the time of testing, the intent object obtained through getintent in the activity always gets the desired information.

Search on the internet found that if you use the same intent, you need to set the flags parameter to Pendingintent.flag_cancel_current when creating pendingintent, as shown below.

Pendingintent.getactivity (atynotification.this, 0, intent, pendingintent.flag_cancel_current)

If not the same intent,flags parameter is not set to Pendingintent.flag_cancel_current

   New Intent (intent.action_view);   Intent2.setdata (Uri.parse ("tel:10086"));   Notification.setcontentintent (Pendingintent.getactivity (atynotification. This, 0, Intent2, 0));
