如何在状态栏中显示没有图标的通知

// 创建通知通道
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    NotificationChannel channel = new NotificationChannel("channel_id", "channel_name", NotificationManager.IMPORTANCE_DEFAULT);
    channel.setDescription("channel_description");
    NotificationManager notificationManager = getSystemService(NotificationManager.class);
    notificationManager.createNotificationChannel(channel);
}

// 创建通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "channel_id")
        .setSmallIcon(R.drawable.transparent_icon) // 设置透明的图标
        .setContentTitle("通知标题")
        .setContentText("通知内容")
        .setPriority(NotificationCompat.PRIORITY_DEFAULT);

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