推荐答案
之所以会发生这种情况，是因为您覆盖了默认的ItemContainerStyle(它为null)并为ListBoxItem设置了新样式，而没有为选定的/未选定的视觉状态提供情节提要.
That happens because you override the default ItemContainerStyle which is null and setting a new style for the ListBoxItem without a storyboard for the Selected / Unselected Visual States.
看看默认样式.阅读本文后，应该做的很简单.
Have a look at the default styles. What you should do will be straightforward after you read the article.
