UWP 在导航视图中使用 Acrylic
UWP Using Acrylic in Navigation View
我正在研究 UWP 的 Acrylic 选项,但遇到了一个奇怪的问题。本质上,我试图让导航视图使用自定义的 Acrylic Brush。但是,主 window 背景比 Navigationview 更透明。
我需要让 NavigationView 像当前主视图一样透明。我附上了一张图片来帮助澄清这一点。很难解释:
如您在左侧所见,导航视图不像右侧的主要功能 window 那样透明。我需要交换它,以便 NavigationView 比 MainPage 更透明。
这是我的 App.XAML
<Application
x:Class="BS.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:BS">
<Application.Resources>
<AcrylicBrush x:Key="CustomAcrylicDark"
BackgroundSource="HostBackdrop"
TintColor="Gray"
TintOpacity="0.6"
FallbackColor="Black"/>
<AcrylicBrush x:Key="CustomAcrylicLight"
BackgroundSource="HostBackdrop"
TintColor="White"
TintOpacity="0.6"
FallbackColor="White"/>
</Application.Resources>
</Application>
这是我的MainPage.XAML
<Page
x:Class="BS.MainPage"

<Grid>
<NavigationView Background="{StaticResource CustomAcrylicDark}" PaneTitle="BS" IsBackButtonVisible="Collapsed" CompactModeThresholdWidth="9999" ExpandedModeThresholdWidth="9999" CompactPaneLength="96">
<NavigationView.MenuItems>
<NavigationViewItem Name="HItem" Content="HOME" Tag="HOME_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItemSeparator/>

<NavigationViewItem Name="PItem" Content="PEOPLE" Tag="B_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItem Name="TItem" Content="TRANSFERS" Tag="T_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItem Name="PItem" Content="PAY DATES" Tag="P_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>

NavigationView
建立在 Splitview
之上。在 Splitview
中,您会发现一个名为 PaneBackground
的 属性,但 NavigationView
不会让您设置 PaneBackground
属性 Splitview
它是在.
但您并非运气不佳,在调查 NavigationView
的模板后,我发现 PaneBackground
属性 绑定到名为 ThemeResource
的 ThemeResource
NavigationViewDefaultPaneBackground
。因此,您的工作是覆盖此 属性。像这样:
<Grid>
<Grid.Resources>
<AcrylicBrush x:Key="NavigationViewDefaultPaneBackground"
BackgroundSource="HostBackdrop"
TintColor="Gray"
TintOpacity="0.6"
FallbackColor="Black"/>
</Grid.Resources>
<NavigationView x:Name="Navview" Background="{StaticResource CustomAcrylicDark}" PaneTitle="BS" IsBackButtonVisible="Collapsed"
CompactModeThresholdWidth="9999" ExpandedModeThresholdWidth="9999" CompactPaneLength="96">
<NavigationView.MenuItems>
<NavigationViewItem Name="HItem" Content="HOME" Tag="HOME_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItemSeparator/>
<NavigationViewItem Name="OItem" Content="OVERVIEW" Tag="O_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItem Name="BItem" Content="BILLS" Tag="B_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItem Name="PItem" Content="PEOPLE" Tag="B_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItem Name="TItem" Content="TRANSFERS" Tag="T_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
<NavigationViewItem Name="PItem2" Content="PAY DATES" Tag="P_Page" FontSize="22" HorizontalAlignment="Center" FontWeight="Bold" Foreground="MediumPurple"/>
</NavigationView.MenuItems>
<Button HorizontalAlignment="Center" Content="{x:Bind Navview.DisplayMode, Mode=OneWay}"/>
</NavigationView>
</Grid>
结果如下:
因此,您可以使用此方法根据需要设置窗格的背景。希望对您有所帮助。
如果您使用的是 PaneDisplayMode="Left",则覆盖 NavigationViewExpandedPaneBackground
<AcrylicBrush x:Key="NavigationViewExpandedPaneBackground"
BackgroundSource="HostBackdrop"
TintColor="Gray"
TintOpacity="0.6"
FallbackColor="Black"/>
