Question

我有一个ListView，当我用鼠标选择一行时，我正在按下，那行会得到一些填充或边距，我不知道它是什么，我只是希望它不会发生，只需选择一行没有任何效果，就像我选择带键盘的行一样。

要更改默认行为，您必须更改ListViewItem的样式。您可以在spinlock或本地驱动器上找到这些样式：

C：\ Program Files（x86）\ Windows Kits \ 10 \ DesignTime \ CommonConfiguration \ Neutral \ UAP \ 10.0.14393.0 \ Generic \ generic.xaml

有问题的视觉状态很可能是Pressed和PressedSelected。将这些视觉状态改变为ListView要做的任何事情。
