隐藏MasterDetailPage上的导航栏

问题描述

我有一个MasterDetailPage，其中包含以下构造函数:

I have a MasterDetailPage that contains the following constructor:

    public MainPage()
    {
        NavigationPage.SetHasNavigationBar(this, false);
        NavigationPage.SetHasBackButton(this, false);
        InitializeComponent();

        MessagingCenter.Subscribe<JobsPage>(this, "OpenMenu", (sender) => {
            IsPresented = true;
        });

        MasterPage.ListView.ItemSelected += ListView_ItemSelected;
        this.MasterBehavior = MasterBehavior.Popover;
        App.NavPage = new NavigationPage(new JobsPage() { Title = "Jobs" });
        Detail = App.NavPage;
    }

如您所见，我将SetHasNavigationBar和SetHasBackButton设置为false.

As you can see, I've set SetHasNavigationBar and SetHasBackButton to false.

在一个不同页面(一个ContentPage，而不是一个MasterDetailPage)上，我在构造函数中做了同样的事情:

On a different page (a ContentPage, not a MasterDetailPage), I did the same thing in the constructor:

    NavigationPage.SetHasNavigationBar(this, false);
    NavigationPage.SetHasBackButton(this, false);
    InitializeComponent();

在我的ContentPage上，它可以正常工作，如下所示.

On my ContentPage, this works fine, as shown below.

但是，在我的MasterDetailPage上，我仍然看到导航栏.

On my MasterDetailPage, however, I'm still seeing the Navigation bar.

我该如何解决?

推荐答案

不确定导航的结构，但是请尝试以下操作:

Not sure how is structured your navigation, but try this:

public MainPage()
{

        InitializeComponent();

        MessagingCenter.Subscribe<JobsPage>(this, "OpenMenu", (sender) => {
            IsPresented = true;
        });

        MasterPage.ListView.ItemSelected += ListView_ItemSelected;
        this.MasterBehavior = MasterBehavior.Popover;

        var navPage = new NavigationPage(new JobsPage() { Title = "Jobs" });
        NavigationPage.SetHasNavigationBar(navPage, false);
        NavigationPage.SetHasBackButton(navPage, false);

        App.NavPage = navPage;
        Detail = App.NavPage;
}
