C＃和XAML - 从Wunderground API在ListView中显示JSON

我是C＃和XAML的新手，正在开发一个简单的天气应用程序，可让您搜索城市和州，并返回格式化的10天预测列表 .

我在使用ListView显示从Wunderground Weather API检索的数据时遇到问题 . 这是我正在使用的JSON，example.

My problem ：在从Wunderground API获取结果后，如何通过XAML中的模板运行所有列表项，以显示项属性'（icon_url，title，fcttext）？

这是我的模型：

public class ForecastList
        {
            public class Forecastday
            {
                public string icon_url { get; set; }
                public string title { get; set; }
                public string fcttext { get; set; }
            }

            public class TxtForecast
            {
                public List forecastday { get; set; }
            }

            public class Forecast
            {
                public TxtForecast txt_forecast { get; set; }
            }

            public class RootObject
            {
                public Forecast forecast { get; set; }
            }
        }

XAML：

<Stack Layout Padding="30"> <StackLayout Orientation="Horizontal"> <Entry HorizontalOptions="FillAndExpand" Placeholder="City" x:Name="City" /> <Entry Placeholder="2 letter state" x:Name="State" /> </StackLayout> <Button Text="Search" Clicked="OnClicked" /> <ListView ItemsSource="{Binding ListSource}"> <ListView.ItemTemplate> <DataTemplate> <Label Text="{Binding Title}" /> <Label Text="{Binding FctText}" /> <Image Source="{Binding IconUrl}" /> </DataTemplate> </ListView.ItemTemplate> </ListView> </StackLayout>

而ViewModel：

public class MainPageViewModel
        {
            public async Task GetWeatherAsync(string url)
            {
                HttpClient client = new HttpClient();
                client.BaseAddress = new Uri(url);

                var response = await client.GetAsync(client.BaseAddress);
                response.EnsureSuccessStatusCode();

                var JsonResult = response.Content.ReadAsStringAsync().Result;

                var weather = JsonConvert.DeserializeObject(JsonResult);
                SetList(weather);
            }

            public List ListSource { get; set; }

            private string _title;
            public string Title 
            { 
                get 
                { 
                    return _title; 
                } 
                set 
                { 
                    _title = value; 
                } 
            }

            private string _fctText;
            public string FctText 
            { 
                get
                {
                    return _fctText;
                }
                set
                {
                    _fctText = value;
                }
            }

            private string _iconUrl;
            public string IconUrl
            {
                get
                {
                    return _iconUrl;
                }
                set
                {
                    _iconUrl = value;
                }
            }

            private void SetList(ForecastList.RootObject weather)
            {
                ListView listView = new ListView();
                var forecastList = weather.forecast.txt_forecast.forecastday;
                List listSource = new List(forecastList);

                ListSource = listSource;

                listView.ItemsSource = ListSource;
            }
        }

干杯!
