仅当两个ListViews至少有1个项目时才启用按钮(通过WPF触发器)

<ListView x:Name="listView1">
    <!-- ListView1的项目 -->
</ListView>

<ListView x:Name="listView2">
    <!-- ListView2的项目 -->
</ListView>

<Button x:Name="button" Content="按钮" IsEnabled="False">
    <!-- 按钮的其他属性和事件处理程序 -->
</Button>

<Button x:Name="button" Content="按钮">
    <Button.Style>
        <Style TargetType="Button">
            <Style.Triggers>
                <DataTrigger Binding="{Binding ElementName=listView1, Path=Items.Count}" Value="0">
                    <Setter Property="IsEnabled" Value="False"/>
                </DataTrigger>
                <DataTrigger Binding="{Binding ElementName=listView2, Path=Items.Count}" Value="0">
                    <Setter Property="IsEnabled" Value="False"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Button.Style>
</Button>
