我必须像在所附照片中那样创建一个框架,因为它必须包含标签/文字,并且必须具有高程和阴影,因此它必须具有适应性。用框架很容易做到所有这些,问题是说话很少,我找不到找到方法。
[也许有人有一个开始的想法。谢谢
您可以将框架的Height和Width与其子元素(如标签)绑定在一起。
public class SizeConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return ((double)value + 20.0); // you can set the logic of height and width here
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return 0;
}
}

<StackLayout VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand">
