XAML 如何在毛伊岛.net中制作全屏网格？

我试图使一个页面有一个顶行（工具栏），在中间的主要内容，然后沿着屏幕底部的状态栏。如果主要内容太大，那么我希望它滚动。应该很简单吧？
下面是我一直在使用的XAML，但似乎不能让它工作。更准确地说-我不能让它在iOS上工作。它在Android上运行良好，但在iOS中，它只是从屏幕底部展开，所以我看不到它。
有什么建议吗？

在解决此问题之前，解决方法是在网格行上设置数字高度。
您必须手动减去其他内容的高度。在您的情况下，从屏幕高度减去200：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="100"/>
        <RowDefinition Height="{Binding ScrollViewRowHeight, Source={RelativeSource Self}" />
        <RowDefinition Height="100"/>
    </Grid.RowDefinitions>

代码隐藏：

public double ScrollViewRowHeight { get; set; }

  ...
  // constructor
  public MyPageNameHere()
  {
      InitializeComponent();

      var screenHeight = Microsoft.Maui.Devices.DeviceDisplay.MainDisplayInfo.Height;
      ScrollViewRowHeight = screenHeight - 200;

      ...
  }
