c# - C#/UWP 按钮选择后隐藏 NavigationView

Question

我遇到了一个问题，即在导航后单击 AppBarButton 不会最小化 NavView。与选择 NavigationViewItem 后自动最小化 NavView 的 NavView_SelectionChanged void 不同。我不确定如何在更新内容框架后隐藏 NavView。

这是 MainPage.xaml.cs

public sealed partial class MainPage : Page
    {

        public MainPage()
        {
            this.InitializeComponent();

            string appName = Windows.ApplicationModel.Package.Current.DisplayName;
        }

        private void NavView_SelectionChanged(Windows.UI.Xaml.Controls.NavigationView sender, Windows.UI.Xaml.Controls.NavigationViewSelectionChangedEventArgs args)
        {
            NavigationViewItem item = args.SelectedItem as NavigationViewItem;

            switch (item.Tag.ToString())
            {
                case "OverView_Page":
                    ContentFrame.Navigate(typeof(Content_Pages.Overview_Page));
                    break;
                case "Bills_Page":
                    ContentFrame.Navigate(typeof(Content_Pages.Bills_Page));
                    break;
                case "BillPayer_Page":
                    ContentFrame.Navigate(typeof(Content_Pages.BillPayer_Page));
                    break;
                case "Transfers_Page":
                    ContentFrame.Navigate(typeof(Content_Pages.Transfers_Page));
                    break;
                case "PayDates_Page":
                    ContentFrame.Navigate(typeof(Content_Pages.PayDates_Page));
                    break;               
            }
        }
       private void SettingsButton_Click(object sender, RoutedEventArgs e)
        {
            ContentFrame.Navigate(typeof(Content_Pages.SettingsPage));
        }
    }

和 MainPage.XAML AppBarButtons：

<mux:NavigationView.MenuItems>
                <StackPanel Orientation="Horizontal" UseLayoutRounding="False">
                    <AppBarButton Icon="Setting" Margin="1, 2, 0, 0" Tag="Settings_Page" HorizontalAlignment="Center" Width="56.5" Height="56.5" ClickMode="Press" Click="SettingsButton_Click"/> 
                </StackPanel>

所有这些都被正确关闭，所以这些只是相关的位。请原谅我缺乏这方面的知识，还在学习中

ContentFrame.Navigate在调用in之后添加这一行SettingsButton_Click：

NavView.IsPanelOpen = false;
