Android notes custom broadcast notification bar

[Java]View plaincopy

1. Notification n = new Notification (android. R. drawable. ic_menu_share, null, System. currentTimeMillis ());

Parameter: icon ID, text instantly sent to the status bar, current time

[Java]View plaincopy

1. PendingIntent contentIntent = PendingIntent. getBroadcast (this, 0, intent, PendingIntent. FLAG_UPDATE_CURRENT );
2. N. setLatestEventInfo (this, "good morning! "," Today is a clear day! ", ContentIntent );

3. Send to notification bar

[Java]View plaincopy

1. Icationicationmanager mNM = (NotificationManager) getSystemService (Context. NOTIFICATION_SERVICE );
2. MNM. notify (1001, n );

This completes the display of a notification, which is very simple!

[Java]View plaincopy

1. Public void setLatestEventInfo (Context context,
2. CharSequence contentTitle, CharSequence contentText, PendingIntent contentIntent ){
3. // TODO: rewrite this to use Builder
4. RemoteViews contentView = new RemoteViews (context. getPackageName (),
5. R. layout. icationication_template_base );
6. If (this. icon! = 0 ){
7. ContentView. setImageViewResource (R. id. icon, this. icon );
8. }
9. If (priority <PRIORITY_LOW ){
10. ContentView. setInt (R. id. icon,
11. "SetBackgroundResource", R. drawable. icationication_template_icon_low_bg );
12. ContentView. setInt (R. id. status_bar_latest_event_content,
13. "SetBackgroundResource", R. drawable. icationication_bg_low );
14. }
15. If (contentTitle! = Null ){
16. ContentView. setTextViewText (R. id. title, contentTitle );
17. }
18. If (contentText! = Null ){
19. ContentView. setTextViewText (R. id. text, contentText );
20. }
21. If (this. when! = 0 ){
22. ContentView. setViewVisibility (R. id. time, View. VISIBLE );
23. ContentView. setLong (R. id. time, "setTime", when );
24. }
25. If (this. number! = 0 ){
26. NumberFormat f = NumberFormat. getIntegerInstance ();
27. ContentView. setTextViewText (R.id.info, f. format (this. number ));
28. }
30. This. contentView = contentView;
31. This. contentIntent = contentIntent;
32. }

We can see that it actually creates a RemoteViews for us using the default layout of the system,

[Java]View plaincopy

1. ContentView. setImageViewResource (R. id. icon, this. icon );

It is actually setting the icon:

[Java]View plaincopy

1. RemoteViews. setImageViewBitmap (int viewId, Bitmap bitmap)

[Java]View plaincopy

1. Class <?> Clazz = Class. forName ("com. android. internal. R$ id ");
3. Field field = clazz. getField ("icon ");
4. Field. setAccessible (true );
5. Id_icon = field. getInt (null );

[Java]View plaincopy

1. N. setLatestEventInfo (context, title, msg, contentIntent );
2. N. flags | = Notification. FLAG_AUTO_CANCEL;
4. If (n. contentView! = Null & icon! = Null ){
5. N. contentView. setImageViewBitmap (InternalID. id_icon, icon );
6. }

Send a notification. Drop down the notification bar to see if the icon has changed. ^_^
