推荐答案

您只需进一步自定义 MenuCell 的布局即可实现此目的.

You just have to customize the layout of the MenuCell further to achieve this.

下面显示的是一个版本，它使用进一步的 Xamarin.Forms.Frame 在每个项目之间创建间距并进行其他一些修改:-

Shown below is a version that uses a further Xamarin.Forms.Frame to create a spacing between each item with a couple other modifications:-

XAML 页面:-

<ListView x:Name="lstItems" />

XAML 代码隐藏:-

lstItems.ItemTemplate = new DataTemplate(typeof(Classes.MenuCell));
lstItems.ItemsSource = new string[] { "Apples", "Bananas", "Pears", "Oranges" };

ViewCell 类:-

public class MenuCell : ViewCell
{
    public MenuCell()
    {
        Label objLabel = new Label
        {
            YAlign = TextAlignment.Center,
            TextColor = Color.Yellow,                
        };
        objLabel.SetBinding(Label.TextProperty, new Binding("."));


        StackLayout objLayout = new StackLayout
        {
            Padding = new Thickness(20, 0, 0, 0),
            Orientation = StackOrientation.Horizontal,
            HorizontalOptions = LayoutOptions.StartAndExpand,
            Children = { objLabel }
        };

        Frame objFrame_Inner = new Frame
        {
            Padding = new Thickness(15, 15, 15, 15),
            HeightRequest = 36,
            OutlineColor = Color.Accent,
            BackgroundColor = Color.Blue,
            Content = objLayout,                
        };

        Frame objFrame_Outer = new Frame
        {
            Padding = new Thickness(0, 0, 0, 10),
            Content = objFrame_Inner
        };

        View = objFrame_Outer;            
    }
}

将导致以下结果:-
