C# 启用大文本时，堆栈布局不适合元素

我正试图使我的应用程序更兼容可访问性功能，当启用大文本时，我无法在水平方向的堆栈中容纳两个元素。你知道我该怎么解决这个问题吗

        StackLayout horisontalContainer = new StackLayout
        {
            Orientation = StackOrientation.Horizontal,
            HorizontalOptions = LayoutOptions.FillAndExpand,
        };

        List<string> dataList = this.registerCountries();
        List<string> numberList = this.registerAreaCodes();
        List<string> pickerData = new List<string>();
        int i = 0;
        foreach (var data in dataList)
        {
            pickerData.Add(data + " +" + numberList[i]);
            i++;
        }

        countryCode = new Picker { Title = "Country code" };
        countryCode.ItemsSource = pickerData;
        countryCode.IsEnabled = true;
        countryCode.SelectedIndex = 0;
        countryCode.SelectedIndexChanged += (sender, args) =>
        {
            var tempValue = countryCode.Items[countryCode.SelectedIndex];
            string[] words = tempValue.Split('+');
            pickerSelection = words[words.Length-1];
        };

        phoneNbrEntry = new Entry
        {
            Placeholder = Localization.MobileNumber,
            FontSize = 18,
            BackgroundColor = Color.White.ToFormsColor(),
            TextColor = Color.Black.ToFormsColor(),
            Keyboard = Keyboard.Telephone,
        };

堆栈布局将不适合其子元素的大小。在您的情况下，最好使用网格而不是堆栈布局，这样我们就可以将选择器和标签的宽度设置为相对值

    Grid grid = new Grid
        {
            HorizontalOptions = LayoutOptions.FillAndExpand,
            VerticalOptions = LayoutOptions.CenterAndExpand,

            Padding = new Thickness(10,0),

            RowDefinitions =
            {
              
              new RowDefinition { Height = new GridLength(60) },
               
            },

            ColumnDefinitions =
            {

              // the width of picker and label will fill half of the screen
              new ColumnDefinition{Width = new GridLength(1, GridUnitType.Star) },
              new ColumnDefinition{Width = new GridLength(1, GridUnitType.Star) },
            }
        };

        var countryCode = new Picker { Title = "Country code" };
        //countryCode.ItemsSource = pickerData;
        countryCode.IsEnabled = true;
        countryCode.TitleColor = Color.Red;
        countryCode.SelectedIndex = 0;

        var phoneNbrEntry = new Entry
        {
            Placeholder = "11111111",
            FontSize = 38,
            BackgroundColor = Color.White,
            TextColor = Color.Black,
            Keyboard = Keyboard.Telephone,
        };

        grid.Children.Add(countryCode,0,0);
        grid.Children.Add(phoneNbrEntry,1, 0);


        
        Content = grid;

    }

现在能用了吗？@LucasZhang MSFT是的。我希望得到一个堆栈解决方案，但我把它改成了网格

    Grid grid = new Grid
        {
            HorizontalOptions = LayoutOptions.FillAndExpand,
            VerticalOptions = LayoutOptions.CenterAndExpand,

            Padding = new Thickness(10,0),

            RowDefinitions =
            {
              
              new RowDefinition { Height = new GridLength(60) },
               
            },

            ColumnDefinitions =
            {

              // the width of picker and label will fill half of the screen
              new ColumnDefinition{Width = new GridLength(1, GridUnitType.Star) },
              new ColumnDefinition{Width = new GridLength(1, GridUnitType.Star) },
            }
        };

        var countryCode = new Picker { Title = "Country code" };
        //countryCode.ItemsSource = pickerData;
        countryCode.IsEnabled = true;
        countryCode.TitleColor = Color.Red;
        countryCode.SelectedIndex = 0;

        var phoneNbrEntry = new Entry
        {
            Placeholder = "11111111",
            FontSize = 38,
            BackgroundColor = Color.White,
            TextColor = Color.Black,
            Keyboard = Keyboard.Telephone,
        };

        grid.Children.Add(countryCode,0,0);
        grid.Children.Add(phoneNbrEntry,1, 0);


        
        Content = grid;

    }
