如何在自定义 Xamarin.Forms ViewCell 的行之间添加分隔符 space？

Question

在this question on Xamarin Forums中， Craig Dunn 教授如何创建带有框架的单元格。

我想在每个单元格之间添加一个 space。

目前细胞似乎粘在一起，ViewCell 没有 space 属性。

Answer 1

您只需进一步自定义 MenuCell 的布局即可。

下面显示的版本使用进一步的 Xamarin.Forms.Frame 在每个项目之间创建间距，并进行了一些其他修改：-

XAML 页:-

<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 class:-

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;            
    }
}

将产生以下结果：-

我的xaml例子：

 <ListView BackgroundColor="Gray" SeparatorVisibility="None" ItemsSource="{Binding Shipments}" x:Name="lstShipments" RowHeight="60">
    <ListView.ItemTemplate>
      <DataTemplate>
        <ViewCell>
          <StackLayout Padding="0,0,0,1">
            <Grid VerticalOptions="Fill" BackgroundColor="White">
              <Grid.ColumnDefinitions>
                <ColumnDefinition Width="1*"></ColumnDefinition>
                <ColumnDefinition Width="60"></ColumnDefinition>
              </Grid.ColumnDefinitions>
              <Label Grid.Column="0" Grid.Row="0" Text="{Binding DestinationCountry}" FontSize="16" />
              <Image Grid.Column="1" Grid.Row="0" Source="box32.png" />
              <Label Grid.Column="0" Grid.Row="1" Text="{Binding ExchangeOfficeDestinationTitle}" FontSize="16" />
              <Label Grid.Column="1" Grid.Row="1" Text="{Binding ShipmentNum}" FontSize="10" />

            </Grid>
          </StackLayout>
        </ViewCell>
      </DataTemplate>
    </ListView.ItemTemplate>
  </ListView>
