Creating Status Bar Notifications | Android Developers
[
http://developer.android.com/guide/topics/ui/notifiers/
notifications.html]
を見ると、
"FLAG_ONGOING_EVENT" flag
Add this to the flags field to group the notification under the
"Ongoing" title in the Notifications window. This indicates that the
application is on-going ― its processes is still running in the
background, even when the application is not visible (such as with
music or a phone call).
"FLAG_NO_CLEAR" flag
Add this to the flags field to indicate that the notification
should not be cleared by the "Clear notifications" button. This is
particularly useful if your notification is on-going.
というフラグがあります。これで用は足りませんか?
(アイコンの表示場所はステータスバーの左側ですが…)
Ongoingの例としては、Musicアプリの再生中を示すアイコンがわかりやすいです。
