推荐答案

您可以使用Easing类 https://developer.xamarin.com/api/type/Xamarin.Forms.Easing/ 为您制作动画元素，因此在滚动时要对其进行动画处理，这里是如何进行动画处理的示例

You can use the Easing class https://developer.xamarin.com/api/type/Xamarin.Forms.Easing/ to do you animation on an element, so when you scroll you animate the element to which you are scrolling here is a sample on how to animate

    var stck = new StackLayout
{
    Orientation = StackOrientation.Vertical,
    Margin = new Thickness(0, 0, 0, 20),
    WidthRequest = 250,
    HorizontalOptions = LayoutOptions.Start,
    Opacity = animate ? 0 : 1
};

stck.FadeTo(1, 1000, Easing.CubicIn);
