拆分视图项目未正确堆叠在汉堡包按钮下方

Question

我正在研究 Visual Studio 2015 并尝试制作汉堡包样式的导航...但是 splitview 窗格的项目自动获得边距，并且没有正确堆叠在汉堡包按钮下方[看附图]。我希望它们正确地堆叠在网格最左侧的 Hamburger 按钮下方。我想使用列表框，这样当用户导航到另一个页面时，它仍然是 selected/highlighted，所以我无法删除它。我已经附上了 MainPage.xaml 代码和我使用过的样式的代码。希望你能帮忙..谢谢！

ListBoxItem 的默认填充（与边距相反）为“12,11,12,13”。尝试将 ListBoxItems 的 Padding 设置为 0 然后它应该向左对齐。要将它设置在中心，您可以这样做：

<ListBoxItem Name="MenuItemUnitConverter" Padding="0">
    <StackPanel Orientation="Horizontal">
        <Image Margin="4" Source="Assets/unitconverterlogo.png" Style="{StaticResource SplitviewLogoStyle}" />
        <TextBlock FontSize="24" Margin="20,0,0,0">
            <Run Text="Unit Converter"/>
        </TextBlock>
    </StackPanel>
</ListBoxItem>

并修改样式，使图像的左边距 + 宽度 + 图像的右边距 = SplitView.Width (4+48+4=56):

<Style TargetType="Image" x:Key="SplitviewLogoStyle">
    <Setter Property="Height" Value="50" />
    <Setter Property="Width" Value="48" />
</Style>
