就目前而言，我至少需要纠正三件事:

As for now I see at least three things you need to correct:

• 在您的MainPage中实现INotifyPropertyChanged，例如:

• implement INotifyPropertyChanged in your MainPage, for example like this:

public partial class MainPage: Page, INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private void RaiseProperty(string name) => PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));

private ObservableCollection<RootObject> weatherObjects;

public ObservableCollection<RootObject> WeatherObjects
{
    get { return weatherObjects; }
    set { weatherObjects= value; RaiseProperty(nameof(WeatherObjects)); }
}

<ListView Grid.Row="2" ItemsSource="{x:Bind WeatherObjects, Mode="OneWay"}">

您无需像使用 x:Bind 那样设置 DataContext .

You don't need to set the DataContext as you are using x:Bind.
