Xaml Can'；t当键盘打开时滚动至结果结束（Windows Phone）

我正在开发Windows Phone应用程序，遇到以下问题： 我有一个显示搜索结果的列表控件，但是当键盘打开时，由于我的键盘，我的一些结果不可见

有没有办法将控件缩小到键盘边框？以查看所有结果

即使打开键盘，我也要滚动到结果结束。

这是我的解决方案

public class ResizeContentOnKeyboardShowingBehavior : Behavior<Page>
    {
        private readonly double _screenHeight;

        public ResizeContentOnKeyboardShowingBehavior()
        {
            _screenHeight = Window.Current.Bounds.Height;
        }

        protected override void OnAttached()
        {
            InputPane.GetForCurrentView().Showing += OnKeyboardShowing;
            InputPane.GetForCurrentView().Hiding += OnKeyboardHiding;
        }

        protected override void OnDetaching()
        {
            InputPane.GetForCurrentView().Showing -= OnKeyboardShowing;
            InputPane.GetForCurrentView().Hiding -= OnKeyboardHiding;
        }

        private void OnKeyboardHiding(InputPane sender, InputPaneVisibilityEventArgs args)
        {
            var content = (FrameworkElement)AssociatedObject.Content;

            content.Height = _screenHeight;
        }

        private void OnKeyboardShowing(InputPane sender, InputPaneVisibilityEventArgs args)
        {
            var content = (FrameworkElement)AssociatedObject.Content;

            double keyboardHeight = sender.OccludedRect.Height;

            content.Height = _screenHeight - keyboardHeight;
        }
    }

这是我的解决办法

public class ResizeContentOnKeyboardShowingBehavior : Behavior<Page>
    {
        private readonly double _screenHeight;

        public ResizeContentOnKeyboardShowingBehavior()
        {
            _screenHeight = Window.Current.Bounds.Height;
        }

        protected override void OnAttached()
        {
            InputPane.GetForCurrentView().Showing += OnKeyboardShowing;
            InputPane.GetForCurrentView().Hiding += OnKeyboardHiding;
        }

        protected override void OnDetaching()
        {
            InputPane.GetForCurrentView().Showing -= OnKeyboardShowing;
            InputPane.GetForCurrentView().Hiding -= OnKeyboardHiding;
        }

        private void OnKeyboardHiding(InputPane sender, InputPaneVisibilityEventArgs args)
        {
            var content = (FrameworkElement)AssociatedObject.Content;

            content.Height = _screenHeight;
        }

        private void OnKeyboardShowing(InputPane sender, InputPaneVisibilityEventArgs args)
        {
            var content = (FrameworkElement)AssociatedObject.Content;

            double keyboardHeight = sender.OccludedRect.Height;

            content.Height = _screenHeight - keyboardHeight;
        }
    }

您的代码可以用作infra，这非常有用！：）这是一个很好的解决方案。我已经实现了它，并且调整了内容的大小，这样键盘就不会与应用程序的窗口重叠，但是内容不会滚动到视图中。我可以点击并拖动内容到视图中。知道为什么吗？找到了原因：我的内容顶部有一个空白，对应于键盘的高度（或者可能是高度的一半）。当我添加

content.VerticalAlignment=VerticalAlignment.Top

时，它解决了这个问题。所以它是关于内容的placemenet，一旦它被调整大小。也许调整父容器的大小比调整内容更好。您的代码可以用作infra，这非常有用！：）这是一个很好的解决方案。我已经实现了它，并且调整了内容的大小，这样键盘就不会与应用程序的窗口重叠，但是内容不会滚动到视图中。我可以点击并拖动内容到视图中。知道为什么吗？找到了原因：我的内容顶部有一个空白，对应于键盘的高度（或者可能是高度的一半）。当我添加
