Question

我有这段代码：

produtos_rl_acompanhamentos.Children.Add(grid_acompanhamentos,
    Constraint.RelativeToParent((parent) =>
    {
        return (parent.Width / 2) - (grid_acompanhamentos.Width / 2);
    }),
    Constraint.RelativeToParent((parent) =>
    {
        return (parent.Height / 2) - (grid_acompanhamentos.Height / 2);
    })
);

produtos_rl_acompanhamentos.Children.Add(prod_acomp_img, Constraint.RelativeToView(grid_acompanhamentos, (parent, sibling) => {
    return sibling.X;
}), Constraint.RelativeToView(grid_acompanhamentos, (parent, sibling) => {
    return sibling.Y;
}), Constraint.RelativeToView(grid_acompanhamentos, (parent, sibling) => {
    return sibling.Width;
}), Constraint.RelativeToView(grid_acompanhamentos, (parent, sibling) => {
    return sibling.Height;
}));

首先创建

grid_acompanhamentos，但我仍然需要prod_acomp_img，因为prod_acomp_img是它的背景。但是，如果我在prod_acomp_img之前添加prod_acomp_img，则代码无法识别grid_acompanhamentos来执行此操作，即我的图像相对于的视图。我该如何解决？

我可以在创建子订单后更改它们吗？

谢谢！

我找到了解决方案：

                relativeLayout.RaiseChild(view);

使用相对布局以编程方式将xamarin表单设置为视图背景
