推荐答案
解决方案要实时更改操作图标,您需要:
Solution To change the icon of action at realtime, you need:
- 获取和替换操作.
- 推送新通知.
例如:
notificationBuilder.actions[1] = new Notification.Action(R.drawable.pause, "play", pendingIntent);
NotificationManager service = ((NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE));
service.notify(101, notificationBuilder);
或
notificationBuilder.actions[1] = new Notification.Action(R.drawable.pause, "play", pendingIntent);
startForeground(101, notificationBuilder);
