Herocard 在 Skype Microsoft 机器人框架中不显示超过 3 个按钮

Question

我在英雄卡片中添加了 6 个按钮并尝试显示它们。它在 Teams 和模拟器中运行良好，但在 Skype 上不起作用。它只显示 3 个按钮。

 private List<CardAction> GetCardButton(List<string> opts)
    {
        List<CardAction> cardButtons = new List<CardAction>();
        int i = 1;
        foreach(string opt in opts)
        {
            CardAction plButton = new CardAction()
            {
                Title = opt,
                Type = "postBack",
                Text = i.ToString(),
                Value = i.ToString()
            };
            cardButtons.Add(plButton);
            i++;
        }

        return cardButtons;

    }
 //passing list of strings.
 List<CardAction> cardButtons = GetCardButton(cardOpts);

        HeroCard plCard = new HeroCard()
        {
            Title = "Try here",
            Text = "with:",
            Buttons = cardButtons

        };
        plAttachment = plCard.ToAttachment();

但在 Skype 中我只看到前 3 个按钮。有什么方法可以使卡片可滚动或减小按钮大小吗？

Answer 1

在 Skype 的卡片中可以显示的按钮数量有限制。该限制取决于包含多少其他文本和媒体元素。

根据文档（参见 https://dev.skype.com/bots/ 中的第 6 部分）

Answer 2

如上一个答案所示，每个频道在具体可以显示的内容、按钮数量、文本长度等方面都有限制。看来您运行受此限制。您可以做的一件事是，如果有三个以上的按钮，则显示另一张卡片并将它们呈现在列表或轮播中。

这里是一个黑客组合代码示例：

using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace Bot_Application13.Dialogs
{
    [Serializable]
    public class RootDialog : IDialog<object>
    {

        public Task StartAsync(IDialogContext context)
        {
            context.Wait(MessageReceivedAsync);

            return Task.CompletedTask;
        }

        private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
        {
            List<Attachment> cards = new List<Attachment>();
            List<CardAction> buttons = new List<CardAction>();
            for (int i = 0; i < 10; i++)
            {
                CardAction ca = new CardAction()
                {
                    Title = i.ToString(),
                    Type = "postBack",
                    Text = i.ToString(),
                    Value = i.ToString()
                };
                buttons.Add(ca);
            }

            var reply = context.MakeMessage();
            GetCardsAttachments(buttons, cards);
            //reply.AttachmentLayout = AttachmentLayoutTypes.List;
            //or
            reply.AttachmentLayout = AttachmentLayoutTypes.Carousel;
            reply.Attachments = cards;

            await context.PostAsync(reply);

            context.Wait(this.MessageReceivedAsync);
        }

        private Attachment GetHeroCard(List<CardAction> buttons)
        {
            var heroCard = new HeroCard();
            //heroCard.Title = "Title";
            heroCard.Buttons = buttons;
            return heroCard.ToAttachment();  
        }

        private void GetCardsAttachments(List<CardAction> buttons, List<Attachment> cards)
        {
            if (buttons.Count <= 3)
            {
                cards.Add(GetHeroCard(buttons));
            }
            else
            {
                var temp = new List<CardAction>();
                for (int i = 0; i < buttons.Count; i++)
                {
                    if (i % 3 != 0)
                    {
                        temp.Add(buttons.ElementAt(i));
                    }
                    else
                    {
                        if (i != 0)
                        {
                            cards.Add(GetHeroCard(temp));
                        }

                        temp = new List<CardAction>();
                        temp.Add(buttons.ElementAt(i));
                    }

                }
                cards.Add(GetHeroCard(temp));
            }
        }
    }
}
