Xamarin表格网格 - C#中"*"的行高？

Question

我知道你可以这样在XAML中用"*"设置行高:

 <RowDefinition Height="Auto" />
 <RowDefinition Height="*" />

但是C#中的相同表达式返回错误:

new RowDefinition { Height = new GridLength("*", GridUnitType.Auto) },

所以我的问题是如何在C#中将网格的行高设置为"*"？

Answer 1

var grid = new Grid ();
grid.RowDefinitions.Add (new RowDefinition { Height = GridLength.Auto });
grid.RowDefinitions.Add (new RowDefinition { Height = new GridLength (1, GridUnitType.Star) });

var stacklayout1 = new StackLayout { HeightRequest = 100, BackgroundColor = Color.Red };
var stacklayout2 = new StackLayout { BackgroundColor = Color.Blue };

Grid.SetRow (stacklayout2, 1);

grid.Children.Add (stacklayout1);
grid.Children.Add (stacklayout2);

MainPage = new ContentPage { Content = grid };
