ScrollView重叠

Question

我尝试在两个StackLayouts之间放置ScrollView StackLayout但是当我滚动ScrollView内的元素时，这些项始终与上级StackLayout重叠在图像中：

我使用的代码是：

stackPrinc = new StackLayout()
{
    Spacing = 0,
    HorizontalOptions = LayoutOptions.FillAndExpand,
    Children = {
        ly_sup,
        new ScrollView() { Content = ly_main, IsClippedToBounds = true, BackgroundColor = Color.Olive },
        ly_inf },
};

Answer 1

我解决了它，当一个元素在他上面和下面有一个元素时，它就会发生一个bug。我的新代码是;

stackPrinc = new StackLayout()
        {
            Spacing = 0,
            Children = {
                ly_sup,
                new StackLayout() { Children =  { new ScrollView() { Content = ly_main, IsClippedToBounds = true, BackgroundColor = Color.Aqua, } } },
                ly_inf,
            },
        };
