如何在Xamarin中定位RelativeLayout中的元素？

RelativeLayout relativeLayout = new RelativeLayout();

// 创建需要定位的元素
Button button1 = new Button();
button1.Text = "Button 1";

Button button2 = new Button();
button2.Text = "Button 2";

// 设置元素的布局属性
relativeLayout.Children.Add(button1,
    Constraint.RelativeToParent((parent) =>
    {
        return parent.Width * 0.2; // 相对于RelativeLayout的宽度的20%
    }),
    Constraint.RelativeToParent((parent) =>
    {
        return parent.Height * 0.3; // 相对于RelativeLayout的高度的30%
    }));

relativeLayout.Children.Add(button2,
    Constraint.RelativeToView(button1, (parent, sibling) =>
    {
        return sibling.X + sibling.Width + 10; // 相对于button1的右侧偏移10个像素
    }),
    Constraint.RelativeToView(button1, (parent, sibling) =>
    {
        return sibling.Y; // 与button1的Y坐标对齐
    }));

// 将RelativeLayout添加到页面中进行显示
Content = relativeLayout;
