尝试在Xamarin中关闭ViewCell.ContextAction on按钮单击

using Xamarin.Forms;

namespace YourNamespace
{
    public class YourPage : ContentPage
    {
        public YourPage()
        {
            var listView = new ListView();
            listView.ItemTemplate = new DataTemplate(typeof(YourViewCell));
            listView.ItemsSource = YourDataList;

            Content = listView;
        }
    }

    public class YourViewCell : ViewCell
    {
        public YourViewCell()
        {
            var button = new Button();
            button.Text = "Close Context Actions";
            button.Clicked += Button_Clicked;

            View = new StackLayout
            {
                Children = { button }
            };

            ContextActions.Add(new MenuItem
            {
                Text = "Action 1",
                Command = new Command(() => { /* Action 1 logic */ })
            });

            ContextActions.Add(new MenuItem
            {
                Text = "Action 2",
                Command = new Command(() => { /* Action 2 logic */ })
            });
        }

        private void Button_Clicked(object sender, EventArgs e)
        {
            var viewCell = (ViewCell)sender;
            viewCell.ForceUpdateSize();
            viewCell.ContextActions = null;
        }
    }
}
