Question

我希望按钮始终位于虚拟键盘的正上方。为此，我需要知道键盘的高度。我怎么能在XF中做到这一点？

在主要活动中设置WindowSoftInputMode = SoftInput.AdjustResize并使用此代码：）

public Page1()
    {
        InitializeComponent();

        var al = new AbsoluteLayout
        {
            HorizontalOptions = LayoutOptions.FillAndExpand,
            VerticalOptions = LayoutOptions.FillAndExpand
        };

        var button = new BoxView {Color = Color.Red, VerticalOptions = LayoutOptions.FillAndExpand};

        var entry = new Entry {HorizontalOptions = LayoutOptions.Fill};

        al.Children.Add(button, new Rectangle(0, App.Dimensions.Height - 120, App.Dimensions.Width, 120));

        al.Children.Add(entry, new Rectangle(10, 50, 200, 60));

        Content = al;

        Content.SizeChanged += (sender, args) =>
        {
            button.Layout(new Rectangle(0, Content.Height - 120, App.Dimensions.Width, 120));
        };

    }

App.Dimensions在MainActivity中进行评估，如下所示：

        DisplayMetrics displayMetrics = Resources.DisplayMetrics;
        App.Dimensions.Height = displayMetrics.HeightPixels / displayMetrics.Density;
        App.Dimensions.Width = displayMetrics.WidthPixels / displayMetrics.Density;

如何确定虚拟键盘高度？
