botton操作系统菜单重叠我的页面Xamarin.Forms

Question

我使用Xamarin.Forms开发了一个标签页应用程序。操作系统导航菜单与我的应用程序重叠。这个菜单可以隐藏吗？

附上一个屏幕截图：

我的XAML是： RootTabbedPage：

    <?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MyTimesheet.MainPage"             
             xmlns:behaviors="clr-namespace:MyTimesheet.Behaviors"             
             xmlns:ViewModels="clr-namespace:MyTimesheet.ViewModels"
            xmlns:pages="clr-namespace:MyTimesheet.Pages"

           behaviors:CurrentTabChangedBehavior.AttachBehavior="true"
            >
    <TabbedPage.BindingContext>
        <ViewModels:MainViewModel></ViewModels:MainViewModel>
    </TabbedPage.BindingContext>

        <pages:ClientiPage Title="Clienti"/>
        <pages:CommessePage Title="Commesse"/>
        <pages:ConsuntivazioniPage Title="Consuntivazioni"/>


    <!--Pages can be added as references or inline-->
</TabbedPage>

我的孩子页面：

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:ViewModels="clr-namespace:MyTimesheet.ViewModels"
             xmlns:Converters="clr-namespace:MyTimesheet.Converters"
             xmlns:Ext="clr-namespace:MyTimesheet.Extensions"
             x:Class="MyTimesheet.Pages.ClientiPage">       
    <ContentPage.BindingContext>
        <ViewModels:ClientiViewModel/>
    </ContentPage.BindingContext>
    <StackLayout >

我找到了一个在xamaring论坛上开发标签页的例子
