I'm using a listView based on itemTemplate. So i need in my template to alternate the background color :
- fist row: white
- second row:gray

我正在使用基于 itemTemplate 的 listView。所以我需要在我的模板中改变背景颜色：
- 第一行：白色
- 第二行：灰色
- 第三行：白色
-第四行：灰色

this is my template:

这是我的模板：

     <DataTemplate x:Key="ItemFlight" >
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="60"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Border Background="#28AADB" Margin="2">
                <Image Source="{Binding Path=IsArrival, Converter={StaticResource BooleanToImageDisplayConverter}}" Width="30" Height="30" VerticalAlignment="Center" Margin="5"/>
            </Border>
            <Grid Grid.Column="1" VerticalAlignment="Center">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="4*"/>
                    <ColumnDefinition Width="3*"/>
                    <ColumnDefinition Width="3*"/>
                    <ColumnDefinition Width="6*"/>
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>

                <TextBlock Text="{Binding FlightName}" FontWeight="Bold" Grid.Column="0" Grid.Row="0"  Margin="10" Style="{StaticResource MyTextBlockStyle}"/>

                <TextBlock Text="{Binding ArrivalOrDepartDateTime, Converter={StaticResource DateTimeConverter}}"  FontWeight="Bold" Grid.Column="0" Grid.Row="1" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>

                <TextBlock Text="{Binding Terminal, Converter={StaticResource StringUpperConverter}}" Grid.Column="1" Grid.Row="0" Margin="10"  Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityReverseConverter}}" Style="{StaticResource MyTextBlockStyle}"/>
                <TextBlock Text="{Binding CityInfo.Name}" Grid.Column="1" Grid.Row="0" Margin="10" Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityConverter}}" Style="{StaticResource MyTextBlockStyle}"/>

                <TextBlock Text="{Binding DepartureTime}"  Grid.Column="1" Grid.Row="1" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>

                <TextBlock Text="{Binding CityInfo.Name}" Grid.Column="2" Grid.Row="0" Margin="10" Style="{StaticResource MyTextBlockStyle}"  Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityReverseConverter}}"/>
                <TextBlock Text="{Binding Terminal, Converter={StaticResource StringUpperConverter}}"  Visibility="{Binding Path=IsArrival,Converter={StaticResource BooleanToVisibilityConverter}}" Grid.Column="2" Grid.Row="0" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>

                <TextBlock Text="{Binding ArrivalTime}" Grid.Column="2" Grid.Row="1" Margin="10" Style="{StaticResource MyTextBlockStyle}"/>

                <TextBlock Text="{Binding Status}" Grid.Column="3" Grid.Row="0" Grid.RowSpan="2" Margin="15" Style="{StaticResource MyTextBlockStyle}"  Foreground="#EA6A1E" FontSize="20" TextWrapping="Wrap" />

            </Grid>

<Window x:Class="TryResponses.MainWindow"

    Title="MainWindow" Height="350" Width="525">
<Window.Resources>
    <vm:MainWindowViewModel x:Key="MainWindowViewModel" />
</Window.Resources>
<Grid Background="LightGray" DataContext="{StaticResource MainWindowViewModel}">
    <Grid.Resources>
        <Style TargetType="ListViewItem">
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="0">
                    <Setter Property="Background" Value="LightBlue" />
                </Trigger>
                <Trigger Property="ItemsControl.AlternationIndex"  Value="1">
                    <Setter Property="Background" Value="LightGray" />
                </Trigger>
            </Style.Triggers>
        </Style>
        <DataTemplate DataType="system:String">
            <!-- put your data template here -->
        </DataTemplate>
    </Grid.Resources>
    <ListView ItemsSource="{Binding Items}" AlternationCount="2" />
</Grid>

I hope this will help.

You should use AlternationCount property and it works on ListBox,ListView or any other control that inherits from ItemsControl. The property definition and two examples are included at
