我需要使用动画自定义RadioButton并修改内部椭圆以获得动画。但是内部椭圆没有加载到中心位置，对此有什么解决方法吗？
我使用了样式，下面给出了示例代码。我刚刚将DoubleAnimation用于内椭圆。
<Style x:Key="RadioButtonStyle" TargetType="RadioButton">
<Setter Property="Background" Value="White"/>
<Setter Property="BorderBrush" Value="LightGray"/>
<Setter Property="Foreground" Value="#333333"/>

先谢谢。

您的父Grid容器是13，而您的椭圆的大小是8。
由于13/8 = 1.625，当使得measure（）/ arrange（）通过以将其设置为水平中心时，间距不能等于内椭圆的中心 - 因此可以预期偏移。
所以你的答案只是简单的数学，如果你想让它正确地将你的Grid父容器大小正确地改为像Height="12" Width="12"那样可以整除的东西，它将按你的要求居中。
希望这有帮助，欢呼！

感谢克里斯，您的解决方案无法正常工作，在更改为14为Grid和8为Ellipse后，其工作正常。我仍然无法理解确切的原因。
