Question

请问我是使用Xamarin android进行android开发的新手，我按照一个教程（https://gist.github.com/AlejandroRuiz/c1338bb0166754c6da3d）了解了如何创建一个viewpager，我做的一切都很正确并且运行良好。这是页面适配器的代码

public class CardsPagerAdapter：Android.Support.V13.App.FragmentStatePagerAdapter { 公共类EventPage { //此树图像的图像ID：公共字符串日期;

        // Caption text for this image:
        public string myEvent;

        // Returns the ID of the image:
        public string Date { get { return date; } }


        // Returns the caption text for the image:
        public string Events { get { return myEvent; } }
    }



    static EventPage[] mCards = {
        new EventPage {date = "12 October",
                       myEvent = "1938 - Production began on \"The Wizard of Oz.\""},
        new EventPage { date = "13 October",
                       myEvent = "1893 The melody for Happy Birthday To You was copyright registered. Happy Birthday was originally published as Good Morning To All in a book called Song Stories for the Kindergarten written by Mildred and Patty Hill." },
        new EventPage { date = "14 October",
                       myEvent = "1835 Henry Blair received a patent in for an improved corn planter." },
        new EventPage { date = "15 October",
                       myEvent = "1991 Pizza Hut was trademark registered." },
        new EventPage { date = "16 October",
                       myEvent = "1900 Frank Sprague was granted a patent for a multi-control for electric trains." },
        new EventPage { date = "17 October",
                       myEvent = "1961 \"HOT ROCKS\" Candy was trademark registered." },
        new EventPage { date = "18 October",
                       myEvent = "1958 - The first computer-arranged marriage took place on Art Linkletter's show." },
        new EventPage { date = "19 October",
                       myEvent = "1986 - Foremost journalist, Dele Giwa, assassinated by a parcel bomb which is often blamed on the Babangida regime" },
    };

    private List<Fragment> mCardsFragments { get; set; }


    public CardsPagerAdapter(FragmentManager fm) : base(fm)
    {

           mCardsFragments = new List<Fragment>{

            new PagerFragment(mCards[0].date, mCards[0].myEvent),
            new PagerFragment(mCards[1].date, mCards[1].myEvent),
            new PagerFragment(mCards[2].date, mCards[2].myEvent),
            new PagerFragment(mCards[3].date, mCards[3].myEvent),
            new PagerFragment(mCards[4].date, mCards[4].myEvent),
            new PagerFragment(mCards[5].date, mCards[5].myEvent),
            new PagerFragment(mCards[6].date, mCards[6].myEvent),
            new PagerFragment(mCards[7].date, mCards[7].myEvent),

        };
    }

    #region implemented abstract members of PagerAdapter

    public override int Count
    {
        get
        {
            return mCardsFragments.Count;
        }
    }

    #endregion

    #region implemented abstract members of FragmentStatePagerAdapter

    public override Fragment GetItem(int position)
    {
        return mCardsFragments[position];
    }

    public override Java.Lang.ICharSequence GetPageTitleFormatted(int position)
    {
        return new Java.Lang.String(mCards[position].date);
    }


    #endregion
}

我现在面临的问题是如何使用循环动态地将值输入到PagerFragment中，因为我从数据库中获取数据。

我需要循环的代码

mCardsFragments =新列表{

//希望循环在这里

            new PagerFragment(mCards[0].date, mCards[0].myEvent),
            new PagerFragment(mCards[1].date, mCards[1].myEvent),
            new PagerFragment(mCards[2].date, mCards[2].myEvent),
            new PagerFragment(mCards[3].date, mCards[3].myEvent),
            new PagerFragment(mCards[4].date, mCards[4].myEvent),
            new PagerFragment(mCards[5].date, mCards[5].myEvent),
            new PagerFragment(mCards[6].date, mCards[6].myEvent),
            new PagerFragment(mCards[7].date, mCards[7].myEvent),

};

Answer 1

mCardsFragments = new List<Fragment>();
for (int i = 0; i < mCards.Count; i++)
{
    mCardsFragments.Add(new PagerFragment(mCards[i].date, mCards[i].myEvent)); 
}

如何在listview寻呼机适配器中使用循环
