读取Xamarin中ListView中动态创建的入口值

// 创建ListView
var listView = new ListView();
listView.ItemTemplate = new DataTemplate(typeof(TextCell));
listView.ItemTemplate.SetBinding(TextCell.TextProperty, "Name"); // 数据绑定

// 设置数据源
List<Item> items = new List<Item>
{
    new Item { Name = "Item 1" },
    new Item { Name = "Item 2" },
    new Item { Name = "Item 3" }
};
listView.ItemsSource = items;

// 读取入口值
listView.ItemSelected += (sender, e) =>
{
    if (e.SelectedItem != null)
    {
        var selectedItem = (Item)e.SelectedItem;
        string entryValue = selectedItem.Name;
        // 在此处进行入口值的处理
    }
};

// 更新入口值
items[0].Name = "Updated Item 1";
((ObservableCollection<Item>)listView.ItemsSource).CollectionChanged += (sender, e) =>
{
    if (e.Action == NotifyCollectionChangedAction.Replace)
    {
        var updatedItem = (Item)e.NewItems[0];
        string updatedValue = updatedItem.Name;
        // 在此处进行入口值的处理
    }
};
