[Android Notes] basic usage of notification and icationicationmanager

1. icationicationmanager and notification are used to set notifications.

The notification setting and other operations are relatively simple. The basic method is to create a notification object and set the notification parameters, then, use the icationicationmanager service running in the system background to send the notification.

The basic steps are as follows:

1) Obtain icationicationmanager:

String NS = context. icationication_service;

Icationicationmanager mnotificationmanager = (notificationmanager) getsystemservice (NS );

2) create a new notification object:

Notification = new notification ();

Notification. Icon = R. drawable. icationication_icon;

You can also create a notification in a slightly more complex way:

Int icon = R. drawable. icationication_icon; // notification icon

Charsequence tickertext = "hello"; // notification text prompt displayed in the status bar

Long when = system. currenttimemillis (); // the time when a notification is generated. It is displayed in the notification information.

Notification = new notification (icon, tickertext, when );

3) Fill in the attributes of notification:

Context context = getapplicationcontext ();

Charsequence contenttitle = "my notification ";

Charsequence contenttext = "Hello world! ";

Intent icationicationintent = new intent (this, myclass. Class );

Pendingintent contentintent = pendingintent. getactivity (this, 0, icationicationintent, 0 );

Notification. setlatesteventinfo (context, contenttitle, contenttext, contentintent );

Notification provides a wide range of mobile phone prompts:

A) notification text prompts displayed in the status bar, such:

Notification. tickertext = "hello ";

B) make a prompt, for example:

Notification. defaults | = notification. default_sound;

Notification. Sound = URI. parse ("file: // sdcard/notification/ringer.pdf ");

Notification. Sound = URI. withappendedpath (audio. Media. internal_content_uri, "6 ");

C) Mobile Phone vibration, such:

Notification. defaults | = notification. default_vibrate;

Long [] vibrate = {0,100,200,300 };

Notification. vibrate = vibrate;

D) LED light flashes, such:

Notification. defaults | = notification. default_lights;

Notification. ledargb = 0xff00ff00;

Notification. ledonms = 300;

Notification. ledoffms = 1000;

Notification. Flags | = notification. flag_show_lights;

4) send notifications:

Private Static final int id_notification = 1;

Micationicationmanager. Y (id_notification, notification );

2. update notifications

To update a notification, you only need to call setlatesteventinfo after setting the notification, and then resend the notification.

3. Custom Notification View
