<ListView x:Name="myListView">
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <StackLayout BackgroundColor="{Binding Color}" Padding="10">
                    <Label Text="{Binding Text}" FontSize="{Binding FontSize}" TextColor="White" />
                </StackLayout>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

public class ListItem
{
    public string Text { get; set; }
    public Color Color { get; set; }
    public double FontSize { get; set; }
}

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();

        // 创建列表项数据集合
        var items = new List<ListItem>
        {
            new ListItem { Text = "Item 1", Color = Color.Red, FontSize = 16 },
            new ListItem { Text = "Item 2", Color = Color.Blue, FontSize = 18 },
            new ListItem { Text = "Item 3", Color = Color.Green, FontSize = 20 }
        };

        // 将数据集合绑定到ListView控件
        myListView.ItemsSource = items;
    }
}
