Android icationicationmanager and notification

Sometimes we runProgramBut you need to give the user a prompt. At this time, you need to use the prompt information, that is, display an icon or text in the prompt bar to remind the user. The following is the implementationCode:

 

Code

  Protected     Void  Shownotification (  Int  ID ){
Charsequence from  =     " Positioning Service  "  ;
Charsequence message  =     "  Running  "  ;

Intent intent  =     New  Intent ();

Pendingintent contentintent  =  Pendingintent. getactivity (  This ,  0  ,
Intent,  0  );


Notif. icon  =  ID;
Notif. setlatesteventinfo (  This  , From, message, contentintent );


Icationicationmanager nm  =  (Icationicationmanager) getsystemservice (notification_service );
Nm. Y (R. String. app_name, notif );


} 

 

The ID indicates the image ID. The text is not added here. You can add the image as needed!

 

In this way, you can change the image.

The following code deletes the prompt:

 

 
  VoidDelenot (){
Icationicationmanager notificationmanager=(Icationicationmanager)This
. Getsystemservice (icationication_service );
Icationicationmanager. Cancel (R. String. app_name );
}
 

 

In this way, we can clear the added notification. If we do not want the system to clear the notification, we need to set the relevant attributes:

 

 

  Notif. flags
 

 

This attribute can be set to not clear or add to the running list.
