如何更新绑定到WPF中集合的listview项？

public class MyCollection : ObservableCollection<MyItem>, INotifyCollectionChanged
{
    public event NotifyCollectionChangedEventHandler CollectionChanged;

    protected override void OnCollectionChanged(NotifyCollectionChangedEventArgs e)
    {
        base.OnCollectionChanged(e);
        CollectionChanged?.Invoke(this, e);
    }
}

public class MyItem : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
