You can Stylethe ListViewItemin xaml directly,
您可以Style将ListViewItem在XAML直接，
Example:
例子：
Assuming your "Harf" variable is a string, you can try
假设您的“Harf”变量是一个字符串，您可以尝试
<ListView Name="notListView"
Width="550"
HorizontalAlignment="Left">
<ListView.Resources>
<Style TargetType="{x:Type ListViewItem}">
<Style.Triggers>
<DataTrigger Binding="{Binding Harf}"
Value="1">
<Setter Property="Background"
Value="Red" />
</DataTrigger>
</Style.Triggers>
</Style>
</ListView.Resources>
...
Now any ListViewRow with "Harf" Value of 1 will have a "Red" Background
现在ListView，“Harf”值为 1 的任何行都将具有“红色”Background
