android - startForeground()时如何隐藏徽章计数

Question

startForeground() 需要创建 NotificationChannel 以便在 Oreo 设备的 Launcher 图标上显示徽章编号 1

如何以编程方式隐藏/禁用它？

因为 Galaxy S8(Oreo) 显示徽章编号 1。
Android 8.0 模拟器也显示点。

这就是我现在正在做的事情。但是 setShowBadge(false) 不起作用

编辑1:

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        NotificationChannel tmpC = new NotificationChannel(id, "basic", NotificationManager.IMPORTANCE_MIN);
        tmpC.setShowBadge(false);

        manager.createNotificationChannel(tmpC);

        Notification notification = new NotificationCompat.Builder(this, id)
                .setChannelId(id)
                .setAutoCancel(true)
                .build();

        startForeground(getPackageName().hashCode(), notification);

您只需调用setShowBadge(false)在您的 NotificationChannel 上目的。

NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

// Create notification channel.
NotificationChannel channel = new NotificationChannel({channel_id}, {name}, {importance});
mChannel.setShowBadge(false); // Disable badges for this notification channel.
mNotificationManager.createNotificationChannel(mChannel);

// Create notification and use channel
Notification notification = new NotificationCompat.Builder(context, {channel_id})
         ...
         .build();

// notify
mNotificationManager.notify({notification_id}, notification)
