【Win10开发】关于汉堡菜单-SplitView的用法

SplitView(汉堡菜单)是win10新加的一种控件，顾名思义，其实就是将视图分割成两部分，废话不多说，下面来介绍一下SplitView的基本用法。

首先介绍几个SplitView经常用到的属性。（我直接搬MSDN的。。。

IsPaneOpen	Read/write	Gets or sets a value that specifies whether the SplitView pane is expanded to its full width.
PaneBackground	Read/write	Gets or sets the Brush to apply to the background of the Pane area of the control.
CompactPaneLength	Read/write	Gets or sets the width of the SplitView pane in its compact display mode.
OpenPaneLength	Read/write	Gets or sets the width of the SplitView pane when it's fully expanded.
DisplayMode	Read/write	Gets of sets a value that specifies how the pane and content areas of a SplitView are shown.

---

DisplayMode就是控制SplitView的展开样式，有4个值，Overlay，Inline，CompactOverlay，CompactInline。具体效果可以自行编写查看。此例中pc版设置为CompactOverlay，mobile版设置为Overlay

好的，介绍完毕，那么我们开始实战。首先看看demo运行的效果。

那么接下来我们先看代码布局，我们采用将汉堡Button单独放在SplitView外面。以下是汉堡Button的布局代码，这里说一下，汉堡图标的样式采用字体图标，字体为Segoe MDL2 Assets，更多图标请点此链接->http://modernicons.io/segoe-mdl2/cheatsheet/

        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
        </Grid.RowDefinitions>
        <StackPanel Grid.Row="0" Height="40" Background="LightGray" Orientation="Horizontal">
            <Button Background="Transparent" BorderThickness="0" VerticalAlignment="Top" Click="Menu_Click">
                <Button.Content>
                    <TextBlock Text="" FontSize="30" FontFamily="Segoe MDL2 Assets" ></TextBlock>
                </Button.Content>
            </Button>
            <TextBlock Margin="10" VerticalAlignment="Center" FontFamily="40" Text="SplitView Demo"></TextBlock>
        </StackPanel>

　　接下来当然就是SplitView的代码了。Pane是可隐藏视图，里面采用的ListView控件，Content是主要视图。

<SplitView Grid.Row="1" x:Name="splitView" CompactPaneLength="48" OpenPaneLength="150"
                       IsPaneOpen="False" PaneBackground="LightGray" DisplayMode="CompactOverlay">
            <SplitView.Pane>
                <ListView x:Name="hambLv" IsItemClickEnabled="True" ItemClick="hambLv_ItemClick">
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <SymbolIcon Symbol="{Binding Symbol}"/>
                                <TextBlock Margin="18" Text="{Binding Text}" />
                            </StackPanel>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>
            </SplitView.Pane>
            <SplitView.Content>
                <TextBlock x:Name="content" FontSize="30"></TextBlock>
            </SplitView.Content>
        </SplitView>

至此，前台代码完成。

后台代码首先是汉堡Button控制SplitView的展开与收起。

         private void Menu_Click(object sender, RoutedEventArgs e)
         {
             splitView.IsPaneOpen = !splitView.IsPaneOpen;
         }

我们定义一个HambList新类用以封装。

     public class HambList
     {
         public string Text { get; set; }
         public Symbol Symbol { get; set; }
     }

然后在页面代码中生成ViewItem，并作为ListView的数据源。

         ObservableCollection<HambList> hambList = new ObservableCollection<HambList>();  //这里注意要引入System.Collections.ObjectModel命名空间;
         protected override void OnNavigatedTo(NavigationEventArgs e)
         {
             hambList.Clear();
             hambList.Add(new HambList { Text = "People", Symbol = Symbol.People });
             hambList.Add(new HambList { Text = "Phone", Symbol = Symbol.Phone });
             hambList.Add(new HambList { Text = "Message", Symbol = Symbol.Message });
             hambList.Add(new HambList { Text = "Mail", Symbol = Symbol.Mail });
             base.OnNavigatedTo(e);
         }

 this.hambLv.ItemsSource = hambList;  //将hambList集合绑定到ListView控件

接下来，我们将List每个项的Text属性显示到Content部分的TextBlock控件里。

         private void hambLv_ItemClick(object sender, ItemClickEventArgs e)
         {
             content.Text = (e.ClickedItem as HambList).Text;
         }

最后，我们判断一下用户设备，如果是mobile就把DisplayMode设置为Overlay。

             ResourceContext resContext = ResourceContext.GetForCurrentView();
             string value = resContext.QualifierValues["DeviceFamily"];
             if (value == "Mobile")
             {
                 splitView.DisplayMode = SplitViewDisplayMode.Overlay;
             }

好了，本文介绍SplitView就此结束。
