要实现Android Oreo通知在状态栏中显示，但不在锁屏和点通知中显示，可以使用以下代码示例：

// 创建通知渠道
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    String channelId = "channel_id";
    CharSequence channelName = "Channel Name";
    int importance = NotificationManager.IMPORTANCE_HIGH;
    NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
    notificationChannel.enableLights(true);
    notificationChannel.setLightColor(Color.RED);
    notificationChannel.enableVibration(true);
    notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_SECRET);

    NotificationManager notificationManager = getSystemService(NotificationManager.class);
    notificationManager.createNotificationChannel(notificationChannel);
}

// 构建通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
    .setSmallIcon(R.drawable.ic_notification)
    .setContentTitle("标题")
    .setContentText("内容")
    .setPriority(NotificationCompat.PRIORITY_HIGH)
    .setVisibility(NotificationCompat.VISIBILITY_SECRET)
    .setAutoCancel(true);

// 发送通知
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, builder.build());

上述代码首先创建了一个通知渠道，并设置了锁屏可见性为VISIBILITY_SECRET，然后使用NotificationCompat.Builder构建通知，并将其锁屏可见性设置为VISIBILITY_SECRET。最后，使用NotificationManagerCompat发送通知。

这样设置后，通知将在状态栏中显示，但在锁屏和点通知中将不会显示。请注意，上述代码中的channel_id需要与通知渠道的ID相匹配。
