1.style

注意绿色标注处，如果想要在Listbox外使用滚动条，此处则要注销ScrollViewer，否则在界面区域只能显示ListBox时会出现点击一下，弹到顶端的问题。

 <Grid.Resources>
            <!--SelectedItem with focus -->
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#FAE388" Opacity="1"/>
            <!--SelectedItem without focus-->
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="LightBlue" Opacity="0.4"/>
            <Style TargetType="ListBoxItem">
                <Style.Triggers>
