Icationicationmanager and notification usage Summary ()

(1) Use the system-defined notification

The following sample code is used:

// Create a icationicationmanager reference

String NS = context. icationication_service;

Icationicationmanager mnotificationmanager = (notificationmanager) getsystemservice (NS );

// Define various attributes of notification

Int icon = R. drawable. 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.

// Use the above attributes to initialize noication

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

/*

* Add sound

* Notification. defaults | = notification. default_sound;

* You can also use the following methods:

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

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

* If you want to repeat the sound until the user responds to the notification, you can add "flag_insistent" to the flags field of notification"

* If the notification ults field of notification includes the "default_sound" attribute, this attribute overwrites the sound defined in the sound field.

*/

/*

* Add vibration

* Notification. defaults | = notification. default_vibrate;

* You can also define your own vibration mode:

* Long [] vibrate = {0,100,200,300}; // vibration starts after 0 milliseconds. The vibration stops after 100 milliseconds, and then the vibration starts again after 200 milliseconds.

* Notification. vibrate = vibrate;

* The long array can be defined as any desired length.

* If the notification ults field of notification includes "default_vibrate", this attribute overwrites the vibration defined in the vibrate field.

*/

/*

* Add LED light reminder

* Notification. defaults | = notification. default_lights;

* You can use your own led reminder mode:

* Notification. ledargb = 0xff00ff00;

* Notification. ledonms = 300; // Bright Time

* Notification. ledoffms = 1000; // destroy time

* Notification. Flags | = notification. flag_show_lights;

*/

/*

* More feature attributes

* Notification. Flags | = flag_auto_cancel; // click this notification in the notification bar and the notification is automatically cleared.

* Notification. Flags | = flag_insistent; // repeat the sound until the user responds to the notification.

* Notification. Flags | = flag_ongoing_event; // put the notification to the "ongoing" group in the notification bar, that is, "running ".

* Notification. Flags | = flag_no_clear; // indicates that the notification is not cleared after you click "clear notification" in the notification bar,

* // Often used with flag_ongoing_event

* Notification. Number = 1; // The number field indicates the number of current events represented by this notification. It will overwrite the status bar icon

* // To use this field, it must start from 1.

* Notification. iconlevel = ;//

*/

// Set the notification event message

Context context = getapplicationcontext (); // Context

Charsequence contenttitle = "my notification"; // the title of the notification bar

Charsequence contenttext = "Hello world! "; // Notification bar content

Intent notificationintent = new intent (this, Main. Class); // click the activity to jump to after the notification

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

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

// Pass the notification to icationicationmanager

Micationicationmanager. Y (0, notification );

To update a notification, you only need to call setlatesteventinfo () again after setting the notification, and then resend the notification, that is, call notify () again ().

(2) Use custom notification

To create a custom notification, you can use remoteviews. To define your own extended message, first initialize a remoteviews object, pass it to the contentview field of notification, and then pass pendingintent to the contentintent field. The following sample code is a complete step:

// 1. Create a custom message layout view. xml

<? XML version = "1.0" encoding = "UTF-8"?>

<Linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android"

Android: layout_width = "fill_parent" Android: layout_height = "fill_parent">

<Imageview Android: Id = "@ + ID/image" Android: layout_width = "wrap_content"

Android: layout_height = "fill_parent" Android: layout_marginright = "10dp"/>

<Textview Android: Id = "@ + ID/text" Android: layout_width = "wrap_content"

Android: layout_height = "fill_parent" Android: textcolor = "#000"/>

</Linearlayout>

// 2. Use the remoteviews method in the program code to define the image and text. Upload the remoteviews object to the contentview field.

Remoteviews contentview = new remoteviews (getpackagename (), R. layout. View );

Contentview. setimageviewresource (R. Id. Image, R. drawable. Icon );

Contentview. settextviewtext (R. Id. Text, "hello, this message is in a custom expanded view ");

Notification. contentview = contentview;

// 3. Define an intent for the contentintent field of notification (note that the setlatesteventinfo () method is not required to use a custom view)

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

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

Notification. contentintent = contentintent;

// 4. Send a notification

Micationicationmanager. Y (2, notification );

// The following is all the sample code

// Create a icationicationmanager reference

String NS = context. icationication_service;

Icationicationmanager mnotificationmanager = (notificationmanager) getsystemservice (NS );

// Define various attributes of notification

Int icon = R. drawable. 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.

// Use the above attributes to initialize noication

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

Remoteviews contentview = new remoteviews (getpackagename (), R. layout. View );

Contentview. setimageviewresource (R. Id. Image, R. drawable. iconempty );

Contentview. settextviewtext (R. Id. Text, "Hello, this is JC ");

Notification. contentview = contentview;

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

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

Notification. contentintent = contentintent;

// Pass the notification to icationicationmanager

Micationicationmanager. Y (0, notification );
