在自定义类Xamarin表单

Question

我想设置自定义类字体大小。你现在我该怎么办？

CustomButton类

  public static readonly BindableProperty PaddingProperty =
        BindableProperty.Create(
            nameof(Padding),
            typeof(Thickness),
            typeof(CustomButton),
            new Thickness(0, 0, 0, 0));

    public static readonly BindableProperty TypeProperty =
        BindableProperty.Create(
            nameof(Type),
            typeof(TypeEnum),
            typeof(CustomButton),
            TypeEnum.Blue
            );

 public Thickness Padding
    {
        get { return (Thickness)GetValue(PaddingProperty); }
        set { SetValue(PaddingProperty, value); }
    }

如果你的“自定义按钮”继承自Xamarin.Forms.Button，你可以设置它的“FontSize”属性。

public class CustomButton : Xamarin.Forms.Button //Inheriting from Xamarin.Forms.Button!
    {
        public static readonly BindableProperty PaddingProperty =
        BindableProperty.Create(
            nameof(Padding),
            typeof(Thickness),
            typeof(CustomButton),
            new Thickness(0, 0, 0, 0));

        public static readonly BindableProperty TypeProperty =
            BindableProperty.Create(
                nameof(Type),
                typeof(TypeEnum),
                typeof(CustomButton),
                TypeEnum.Blue
                );

        public Thickness Padding
        {
            get { return (Thickness)GetValue(PaddingProperty); }
            set { SetValue(PaddingProperty, value); }
        }

        public CustomButton()
        {
            FontSize = 123; //FontSize property on Xamarin.Forms.Button
        }
    }
