Android Pendingintent use notifications to pass multiple parameters and do not overwrite issues

intent updateintent = new Intent (Getnoticeservice.this, Detailgonggaoactivity.class); Updateintent.putextra ("type", "Weidu"); Updateintent.putextra ("title", (String) Json.get ("title")); Updateintent.putextra ("id", Json.get ("Noticeid"). toString ());// Add this sentence will not appear the same activity occurred multiple times updateintent.addflags (intent.flag_activity_clear_top);//The following parameters, is the key to set pendingintent Updatependingintent = Pendingintent.getactivity (Getnoticeservice.this, I, UpdateIntent, Pendingintent.flag_update_current); Notification updatenotification = new Notification ();//Set the notification bar to display the contents Updatenotification.icon = R.drawable.logo; Updatenotification.flags |= updatenotification.flag_auto_cancel;updatenotification.tickertext = "The field Wizard sent a new announcement notice"; Updatenotification.defaults = notification.default_sound;//ringtone Alert Updatenotification.setlatesteventinfo ( Getnoticeservice.this, "The field Elf sent a new announcement notice", (String) json.get ("title"), Updatependingintent); Updatenotificationmanager.notify (i, updatenotification); 

　　

Add this sentence will not appear the same activity occurred multiple times, do not explain updateintent.addflags (intent.flag_activity_clear_top);

Updatenotificationmanager.notify (i, updatenotification); This sentence passed I marked the location of updatenotification and the ID of the same time to overwrite the original updatenotification, so to pass a different ID, so that the different updatenotification do not overwrite.

Pendingintent updatependingintent = pendingintent.getactivity (Getnoticeservice.this, I, UpdateIntent, Pendingintent.flag_update_current); Notification updatenotification = new Notification ();
Flags have four values:
int flag_cancel_current: If the pendingintent already exists, the current is canceled before the new is generated.
int flag_no_create: If the pendingintent does not exist, return null directly instead of creating a pendingintent.
int Flag_one_shot: The pendingintent can only be used once, and is automatically canceled after the Send () method executes.
int flag_update_current: If the pendingintent already exists, the current data is updated with the newly-passed intent.

We need to change the last parameter to Pendingintent.flag_update_current, so that in the activated activity we can receive the data from the receiving intent normally.

The previous ID works the same
