NotificationListenerService 获取通知图标? [英] NotificationListenerService get Notification Icon?

问题描述

在扩展新的 (SDK18, JB-4.3) NotificationListenerService 的服务中，我想获得通知的状态栏图标.

In a Service extending the new (SDK18, JB-4.3) NotificationListenerService, I'd like to get the Notification's status bar icon.

mStatusBarNotification.getNotification().icon 返回状态栏可绘制的资源 ID，但该资源 ID 自然不在我的应用程序的范围/资源内.还有 mStatusBarNotification.getNotification().largeIcon(返回一个 Bitmap)，但这不是为所有通知设置的并返回错误"图标(扩展通知中的图像抽屉).

mStatusBarNotification.getNotification().icon returns the resource id of the status bar drawable, but that resource id is naturally not within my app's scope/resources. There's also mStatusBarNotification.getNotification().largeIcon (returning a Bitmap), but that's not set for all notifications and returns the "wrong" icon (the image in the expanded notification drawer).

推荐答案

在 StatusBarNotification 上使用 getPackageName() 来找出发布 Notification<的应用程序/代码>.然后你可以 使用 createPackageContext() 获取该包的 Context，然后使用该 Context 检索图像(例如，通过 getResources()).

Use getPackageName() on StatusBarNotification to find out the app that posted the Notification. You can then use createPackageContext() to get a Context for that package, then use that Context to retrieve the image (e.g., via getResources()).
