答案 0 :(得分：3)
我正在开发一个UWP应用程序，涉及使用此类导航。 让我为您提供基本代码，然后您可以根据需要对其进行修改。
所以，我的XAML看起来像这样：
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<RelativePanel Grid.Row="0" Background="Blue">
<Button x:Name="button" Content="" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="50" Height="50" Foreground="White" BorderBrush="{x:Null}" Background="{x:Null}" FontFamily="Segoe MDL2 Assets" RelativePanel.AlignLeftWithPanel="True" Click="button_Click"/>
<TextBlock x:Name="textBlock" TextWrapping="Wrap" Text="Your App Name" Foreground="#FFF7F7F7" RelativePanel.AlignVerticalCenterWithPanel="True" RelativePanel.AlignRightWith="" RelativePanel.RightOf="button" Margin="10,0,0,0" FontSize="22"/>
</RelativePanel>
<SplitView x:Name="MySplitView" IsPaneOpen="False" OpenPaneLength="220" Grid.Column="0" PaneBackground="SkyBlue" Grid.Row="1" d:LayoutOverrides="LeftMargin, RightMargin, TopMargin, BottomMargin">
<SplitView.Pane>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ListView x:Name="_one" Margin="10,0">
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Tapped="TextBlock_Tapped" Text="{Binding}" SelectionHighlightColor="{x:Null}" Foreground="White"/>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ListView x:Name="_two" Grid.Column="1" Margin="10,0">
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Tapped="TextBlock_Tapped_1" Text="{Binding}" SelectionHighlightColor="{x:Null}" Foreground="White"/>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ListView x:Name="_three" Grid.Column="2" Margin="10,0">
<ListView.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" SelectionHighlightColor="{x:Null}" Foreground="White"/>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
</SplitView.Pane>
<Grid>
<TextBlock Text="Your Content" VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="36"/>
</Grid>
</SplitView>
</Grid>
如您所见，我有一个名为“MySplitView”的SplitView控件。
它有一个窗格和一个网格。
窗格包含导航，而网格包含应用程序的内容。
Pane分为三列，每列包含ListView。
三个ListView包含一个简单的TextBlock控件，用于在该TextBlock控件上显示项目和单击事件，以显示基于该项目的辅助或第三个子列表。
背后的代码是：
public List<string> mainList;
public List<SubItem> secondList, thirdList;
public BlankPage1()
{
this.InitializeComponent();
mainList = new List<string>();
mainList.Add("Main Item 1");
mainList.Add("Main Item 2");
mainList.Add("Main Item 3");
mainList.Add("Main Item 4");
mainList.Add("Main Item 5");
secondList = new List<SubItem>();
secondList.Add(new SubItem { mainItem = "Main Item 1", subItem = "Second Item 1" });
secondList.Add(new SubItem { mainItem = "Main Item 1", subItem = "Second Item 2" });
secondList.Add(new SubItem { mainItem = "Main Item 1", subItem = "Second Item 3" });
secondList.Add(new SubItem { mainItem = "Main Item 2", subItem = "Second Item 1" });
secondList.Add(new SubItem { mainItem = "Main Item 2", subItem = "Second Item 2" });
secondList.Add(new SubItem { mainItem = "Main Item 2", subItem = "Second Item 3" });
secondList.Add(new SubItem { mainItem = "Main Item 3", subItem = "Second Item 1" });
secondList.Add(new SubItem { mainItem = "Main Item 3", subItem = "Second Item 2" });
secondList.Add(new SubItem { mainItem = "Main Item 3", subItem = "Second Item 3" });
secondList.Add(new SubItem { mainItem = "Main Item 4", subItem = "Second Item 1" });
secondList.Add(new SubItem { mainItem = "Main Item 4", subItem = "Second Item 2" });
secondList.Add(new SubItem { mainItem = "Main Item 4", subItem = "Second Item 3" });
secondList.Add(new SubItem { mainItem = "Main Item 5", subItem = "Second Item 1" });
secondList.Add(new SubItem { mainItem = "Main Item 5", subItem = "Second Item 2" });
secondList.Add(new SubItem { mainItem = "Main Item 5", subItem = "Second Item 3" });
thirdList = new List<SubItem>();
thirdList.Add(new SubItem { mainItem = "Second Item 1", subItem = "Third Item 1" });
thirdList.Add(new SubItem { mainItem = "Second Item 1", subItem = "Third Item 2" });
thirdList.Add(new SubItem { mainItem = "Second Item 1", subItem = "Third Item 3" });
thirdList.Add(new SubItem { mainItem = "Second Item 1", subItem = "Third Item 4" });
thirdList.Add(new SubItem { mainItem = "Second Item 2", subItem = "Third Item 1" });
thirdList.Add(new SubItem { mainItem = "Second Item 2", subItem = "Third Item 2" });
thirdList.Add(new SubItem { mainItem = "Second Item 2", subItem = "Third Item 3" });
thirdList.Add(new SubItem { mainItem = "Second Item 2", subItem = "Third Item 4" });
thirdList.Add(new SubItem { mainItem = "Second Item 3", subItem = "Third Item 1" });
thirdList.Add(new SubItem { mainItem = "Second Item 3", subItem = "Third Item 2" });
thirdList.Add(new SubItem { mainItem = "Second Item 3", subItem = "Third Item 3" });
thirdList.Add(new SubItem { mainItem = "Second Item 3", subItem = "Third Item 4" });
_one.ItemsSource = mainList;
}
public class SubItem
{
public string mainItem { get; set; }
public string subItem { get; set; }
}
private void TextBlock_Tapped(object sender, TappedRoutedEventArgs e)
{
//Main Item is clicked
//To show Second Item list
TextBlock tb = sender as TextBlock;
List<string> seconditems = new List<string>();
foreach(SubItem s in secondList)
{
if(s.mainItem == tb.Text)
{
seconditems.Add(s.subItem);
}
}
this._two.ItemsSource = seconditems;
this._two.UpdateLayout();
//In case the user clicks the Main Item when already Third list has items
_three.ItemsSource = null;
this._three.UpdateLayout();
//Set OpenPaneLength manually so Items look nice
MySplitView.OpenPaneLength = _one.Width + _two.Width + 50;
this.MySplitView.UpdateLayout();
}
private void button_Click(object sender, RoutedEventArgs e)
{
//To Open Close SplitView
MySplitView.IsPaneOpen = !MySplitView.IsPaneOpen;
}
private void TextBlock_Tapped_1(object sender, TappedRoutedEventArgs e)
{
// Secondary Item is clicked
// To show thirdlist
TextBlock tb = sender as TextBlock;
List<string> thirditems = new List<string>();
foreach (SubItem s in thirdList)
{
if (s.mainItem == tb.Text)
{
thirditems.Add(s.subItem);
}
}
this._three.ItemsSource = thirditems;
this._three.UpdateLayout();
//Set OpenPaneLength manually so Items look nice
MySplitView.OpenPaneLength = _one.Width + _two.Width + _three.Width+ 50;
this.MySplitView.UpdateLayout();
}
希望这有帮助。
祝你有个美好的一天。
