Xamarin学习笔记 -ListVew

1，ListView：纵向列表

2，需要数据适配器呈现

3，SimpleAdapter 适配器

    public class AppDataViewModel:MvxViewModel
    {

        public Dictionary<string, object> Channel = new Dictionary<string, object>();
        public string test { get; set; } = "我是个测试";
        public override void Start()
        {
            base.Start();

        }
        public AppDataViewModel()
        {
            Channel.Add("1号菜单", "");
            Channel.Add("2号菜单", "");
            Channel.Add("3号菜单", "");
        }

    }
            AppDataViewModel avm = new AppDataViewModel();
            var list1 = new List<IDictionary<string, object>>();

            foreach(var c  in avm.Channel)
            {
                JavaDictionary<string, object> jd = new JavaDictionary<string, object>();  //注意这里需要的是JavaDictionary
                jd.Add("txt", c.Key); //字段key　　　　　　　　　//jd.Add("xx",xx)
                list1.Add(jd);
             }

            sa = new SimpleAdapter(this,
                list1,
                Resource.Layout.main_menuItem, //item的样式布局文件
                new string[] { "txt" }, //对应的字段key
                new int[] { Resource.Id.main_menuItem_id }); //item样式布局文件中需要绑定的元素id，将会对应到数据的字段key
            var menu = (ListView)FindViewById(Resource.Id.menu);
            menu.Adapter = sa;
