Question

我很难找到解决方案，所以不胜感激。

我需要能够在鼠标结束时更改GridView行的背景，或者如果选择了行，则需要更改。

这是我的ListView样式。

    <Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}"
   TargetType="ScrollViewer">
    <Setter Property="Template">

我最接近答案的是这篇文章（代码在我的Style中省略，因为它没有任何效果）： -

Change ListViewItem background colour on mouse over

但是，我仍然无法控制鼠标悬停和所选颜色。我越来越近，因为上面的帖子表明这是一个实际上正在进行突出显示和选择的按钮，但我不知道如何将其融入我现有的风格中。

这是Style的当前效果。选择了第一行，第三行是鼠标，另外两行是正常的。

Mouseover / selected colours

顺便说一句，我使用的样式是从Blend中提取的，我调整它以使用我的app颜色。

我不认为我的班级代码在这里是相关的，但如果我错了，请纠正我，我会发布。

我认为您需要为ListViewItems添加样式并设置ListView.ItemContainerStyle：

<!-- New style -->
<Style x:Key="StyleListViewItem" TargetType="ListViewItem">
  <Style.Triggers>
    <Trigger Property="IsMouseOver" Value="True">
      <Setter Property="Background" Value="Green"/>
    </Trigger>
    <Trigger Property="IsSelected" Value="True">
      <Setter Property="Background" Value="Blue"/>
    </Trigger>
  </Style.Triggers>
</Style>

<!-- Existing style -->
<Style x:Key="StyleListView" TargetType="ListView">
  <Setter Property="ItemContainerStyle" Value="{StaticResource StyleListViewItem}"/>
  <Setter Property="SnapsToDevicePixels" Value="true"/>
  <!-- ... -->
</Style>
