使用ObservableCollection未正确更新ListView

// 定义一个数据模型类，实现INotifyPropertyChanged接口
public class Item : INotifyPropertyChanged
{
    private string name;
    public string Name
    {
        get { return name; }
        set
        {
            if (name != value)
            {
                name = value;
                OnPropertyChanged(nameof(Name));
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

// 在ViewModel中使用ObservableCollection
public class ViewModel
{
    public ObservableCollection<Item> Items { get; set; }

    public ViewModel()
    {
        Items = new ObservableCollection<Item>();
    }

    public void AddItem(string name)
    {
        Items.Add(new Item { Name = name });
    }
}

// 在View中绑定ListView到ViewModel的Items属性
<ListView ItemsSource="{Binding Items}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Name}" />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>
