Page.BottomAppBar - 下方应用程序栏控件
Page.TopAppBar - 上方应用程序栏控件 AppBar - 应用程序栏控件
IsOpen - 是否打开 AppBar
IsSticky - 是否是粘性的 AppBar(即在点击非 AppBar 区域时,是否不会关闭 AppBar),默认值 false
ClosedDisplayMode - 应用程序栏关闭状态下的显示模式
Minimal - 最小化模式,只显示省略号,此值为默认值(CommandBar 的 ClosedDisplayMode 的默认值为 Compact)
Hidden - 隐藏
Compact - 显示 icon,但是不会给 label 留出位置
Opening, Opened, Closing, Closed - 几个事件,不解释

<Page.BottomAppBar>
<AppBar x:Name="appBar">
<StackPanel Name="buttonPanel" Orientation="Horizontal" HorizontalAlignment="Left"> <!--

Controls/NavigationControl/AppBarDemo.xaml.cs
/*
* AppBar - 应用程序栏控件(继承自 ContentControl, 请参见 /Controls/BaseControl/ContentControlDemo/)
*
*
* 注:
* 1、当应用程序栏只有实现了 ICommandBarElement 接口(AppBarButton, AppBarToggleButton, AppBarSeparator)的控件的时候建议使用 CommandBar(文档推荐在 uwp 中使用 CommandBar)
* 文档说 uwp 中的 CommandBar 内可以包含非 ICommandBarElement 接口的控件,但是实测发现并不可以
* 2、如果除了实现了 ICommandBarElement 接口(AppBarButton, AppBarToggleButton, AppBarSeparator)的控件之外,应用程序栏还需要其他元素,则需要使用 AppBar

2、CommandBar 的示例
Controls/NavigationControl/CommandBarDemo.xaml
<Page
x:Class="Windows10.Controls.NavigationControl.CommandBarDemo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Windows10.Controls.NavigationControl"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"> <Grid Background="Transparent">
<StackPanel Margin="10 0 10 10"> <CheckBox Name="chkIsSticky" Margin="5" Content="IsSticky" IsChecked="False" Checked="chkIsSticky_Checked" Unchecked="chkIsSticky_Unchecked" />
<StackPanel Margin="5" Orientation="Horizontal">
<RadioButton Name="radioButtonMinimal" GroupName="myGroup" Content="AppBarClosedDisplayMode.Minimal" Checked="radioButtonMinimal_Checked" />
<RadioButton Name="radioButtonHidden" GroupName="myGroup" Margin="10 0 0 0" Content="AppBarClosedDisplayMode.Hidden" Checked="radioButtonHidden_Checked" />
<RadioButton Name="radioButtonCompact" GroupName="myGroup" Margin="10 0 0 0" IsChecked="True" Content="AppBarClosedDisplayMode.Compact" Checked="radioButtonCompact_Checked" />
</StackPanel> <Button Name="btnOpen" Margin="5" Content="打开 CommandBar" Click="btnOpen_Click" />
<Button Name="btnClose" Margin="5" Content="关闭 CommandBar" Click="btnClose_Click" /> </StackPanel>
</Grid> <!--
Page.BottomAppBar - 下方应用程序栏控件
Page.TopAppBar - 上方应用程序栏控件 CommandBar - 应用程序栏控件。相对于 AppBar 来说, CommandBar 易用性强,扩展性弱(在 CommandBar 内只能包含 AppBarButton, AppBarToggleButton, AppBarSeparator)。CommandBar 继承自 AppBar
IsOpen - 是否打开 CommandBar
IsSticky - 是否是粘性的 CommandBar(即在点击非 CommandBar 区域时,是否不会关闭 CommandBar),默认值 false
ClosedDisplayMode - 应用程序栏关闭状态下的显示模式
Minimal - 最小化模式,只显示省略号
Hidden - 隐藏
Compact - 显示 PrimaryCommands 中的按钮的 icon,但不显示其 label,且 SecondaryCommands 中的按钮不会显示,此值为默认值(AppBar 的 ClosedDisplayMode 的默认值为 Minimal)
Opening, Opened, Closing, Closed - 几个事件,不解释 注:无法手动设置 CommandBar 中的 AppBarButton, AppBarToggleButton, AppBarSeparator 的 IsCompact 属性,其如何设置由系统自己决定(比如 Compact 模式的关闭状态的 CommandBar 会隐藏 label,打开状态的 CommandBar 会显示 label)
-->
<Page.BottomAppBar>
<CommandBar x:Name="commandBar"> <!--
关于 AppBarButton 请参见 /Controls/ButtonControl/AppBarButtonDemo.xaml
关于 AppBarToggleButton 请参见 /Controls/ButtonControl/AppBarToggleButtonDemo.xaml
--> <AppBarToggleButton Icon="Shuffle" Label="Shuffle" />
<AppBarToggleButton Icon="RepeatAll" Label="Repeat" />
<AppBarSeparator/>
<AppBarButton Icon="Back" Label="Back" />
<AppBarButton Icon="Stop" Label="Stop" />
<AppBarButton Icon="Play" Label="Play" />
<AppBarButton Icon="Forward" Label="Forward" />
<AppBarSeparator/>
<!--
AppBarButton 是支持 Flyout 的
-->
<AppBarButton Icon="Add" Label="Add">
<AppBarButton.Flyout>
<MenuFlyout>
<MenuFlyoutItem Text="MenuFlyout Item 1"/>
<MenuFlyoutItem Text="MenuFlyout Item 2"/>
<MenuFlyoutItem Text="MenuFlyout Item 3"/>
</MenuFlyout>
</AppBarButton.Flyout>
</AppBarButton> <!--
CommandBar.PrimaryCommands - 其内的按钮会显示在 CommandBar 内部的右侧([ContentProperty(Name = "PrimaryCommands")])
CommandBar.SecondaryCommands - 其内的按钮会显示在 CommandBar 的上部(只显示 label,不显示 icon)
-->
<CommandBar.SecondaryCommands>
<AppBarButton Icon="Like" Label="Like" />
<AppBarButton Icon="Dislike" Label="Dislike" />
</CommandBar.SecondaryCommands> <!--
设置 CommandBar 或 AppBar 的 Style 自然是通过 AppBar.Style
那么如何设置 CommandBar.SecondaryCommands 的样式呢?可以通过 CommandBar.CommandBarOverflowPresenterStyle
-->
<CommandBar.CommandBarOverflowPresenterStyle>
<Style TargetType="CommandBarOverflowPresenter">
<Setter Property="Background" Value="Black" />
</Style>
</CommandBar.CommandBarOverflowPresenterStyle>
</CommandBar>
