如何从 URL 图像 Nougat 及以上操作系统版本设置自定义通知图标？

Question

我已经在通知中通过图像 URL 实现了自定义图标，这是通过使用以下代码获取默认远程视图来实现的

RemoteViews contentView = notification.contentView;
                RemoteViews bigContentView = notification.bigContentView;
                int bigIconId = context.getResources().getIdentifier("android:id/big_picture", null, null);
                int iconId = context.getResources().getIdentifier("android:id/icon", null, null);
                int smallIconId = context.getResources().getIdentifier("right_icon", "id", android.R.class.getPackage().getName());
                int largeIconExId = context.getResources().getIdentifier("profile_badge", "id", android.R.class.getPackage().getName());
                if (finalSmallIcon != null)
                    Picasso.with(context).load(finalSmallIcon).into(contentView, iconId, finalData_id, notification);
                if (finalLargeIcon != null) {
                    Picasso.with(context).load(finalLargeIcon).into(contentView, iconId, finalData_id, notification);
                    Picasso.with(context).load(finalLargeIcon).into(contentView, largeIconExId, finalData_id, notification);
                }
                if (finalSmallIcon != null)
                    Picasso.with(context).load(finalSmallIcon).into(contentView, smallIconId, finalData_id, notification);

                if (finalBigPicture != null) {
                    //  Picasso.with(context).load(finalLargeIcon).into(bigContentView, iconId, finalData_id, notification);
                    Picasso.with(context).load(finalBigPicture).into(bigContentView, bigIconId, finalData_id, notification);
                }
            }
        });

但在 Nougat 及更高版本中，从“notification.contentView”中获取 null。那么如何使用 customLayout 和 RemoteView 类更新 Nougat 及更高版本中的通知图标。 提前致谢。

    NotificationCompat.Builder notificationBuilder = new notificationCompat.Builder(context);
        notificationBuilder
                .setSmallIcon(context.getApplicationInfo().icon);
        notificationBuilder.setLargeIcon(largeIcon != null &&!largeIcon.isEmpty()? Picasso.with(context).load(largeIcon).get() : BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher));
