java - 在 Android P 和 Q Beta 中以编程方式切换异常时出现意外行为

Question

我有一个非常简单的应用程序，只有一个按钮。当我按下此按钮时，我希望以编程方式切换“仅来自已加星标的联系人”和“播放媒体声音”。我正在使用的代码是：

private void setPolicyStarredContacts() {
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    assert notificationManager != null;
    notificationManager.setNotificationPolicy(
            new NotificationManager.Policy(PRIORITY_CATEGORY_MEDIA,
                    NotificationManager.Policy.PRIORITY_SENDERS_STARRED,
                    NotificationManager.Policy.PRIORITY_SENDERS_ANY));

}

实际发生的是只有“播放媒体声音”被激活，而不是其他选项。对于我做错了什么的一些迹象，我将不胜感激。干杯!

Ok, I have actually found the answer! Here it is for future searchers:

private void setPolicyStarredContacts() {
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    assert notificationManager != null;
    notificationManager.setNotificationPolicy(
            new NotificationManager.Policy(PRIORITY_CATEGORY_CALLS | PRIORITY_CATEGORY_MEDIA,
                    NotificationManager.Policy.PRIORITY_SENDERS_STARRED,
                    NotificationManager.Policy.PRIORITY_SENDERS_ANY));

}
