如何在Xamarin中从代码后台向堆栈布局添加自定义视图

// MainPage.xaml.cs

using Xamarin.Forms;

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

        // 创建自定义视图的对象
        var customView = new CustomView();

        // 将自定义视图添加到堆栈布局控件中
        stackLayout.Children.Add(customView);
    }
}

// CustomView.cs

using Xamarin.Forms;

public class CustomView : ContentView
{
    public CustomView()
    {
        // 自定义视图的布局和逻辑
        var label = new Label
        {
            Text = "这是自定义视图",
            HorizontalOptions = LayoutOptions.Center,
            VerticalOptions = LayoutOptions.Center
        };

        // 将Label添加到自定义视图的内容中
        Content = label;
    }
}
