Xamarin形成绝对布局而不是相对布局

RelativeLayout relativeLayout = new RelativeLayout();

// 创建一个元素并设置其位置和大小
Button button = new Button();
button.Text = "Button";
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WrapContent,
    RelativeLayout.LayoutParams.WrapContent);
layoutParams.LeftMargin = 100;
layoutParams.TopMargin = 200;
relativeLayout.AddView(button, layoutParams);

// 创建另一个元素并设置其位置和大小
Label label = new Label();
label.Text = "Label";
RelativeLayout.LayoutParams layoutParams2 = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WrapContent,
    RelativeLayout.LayoutParams.WrapContent);
layoutParams2.AddRule(LayoutRules.Below, button.Id);
layoutParams2.LeftMargin = 100;
relativeLayout.AddView(label, layoutParams2);

// 将RelativeLayout设置为页面的内容
Content = relativeLayout;
