Icationicationmanager and notification usage Summary

Twigee'sSource code, One of the functions to be added is the resident notification column, which can only appear in the "Notification" group when previously written, I want to put it in the "running" group, but I don't know how to put it. I checked the official document and found the method. I just needed to add "flag_ongoing_event" to the flags field of notification. At the same time, I also summarized the usage of notification. See the following for details:

(1) Use the system-defined notification

The following is an exampleCode:

// 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.ProgramThe remoteviews method is used in the 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 are all sample codes. // 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 );
