Xamarin Building菜单

Question

我正在处理Xamarin顶部菜单，当前正在选择菜单文本，它会显示页面列表。但是我有点迷失了如何更改它以使用HamburgerMenu图标。我添加了按钮图像控件，但它不会替换菜单文本。 enter code here>是否需要在mainPage.xaml中添加它？

MainPage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:pages="clr-namespace:ReimbursementApp.Pages"
             x:Class="ReimbursementApp.Pages.MainPage"
             xmlns:telerikPrimitives="clr-namespace:Telerik.XamarinForms.Primitives;assembly=Telerik.XamarinForms.Primitives">
    <MasterDetailPage.Master>
        <pages:MenuPage />
    </MasterDetailPage.Master>
    <MasterDetailPage.Detail>
        <NavigationPage>
            <x:Arguments>
                <pages:ItemsPage />
            </x:Arguments>
        </NavigationPage>
    </MasterDetailPage.Detail>
</MasterDetailPage>

menupage.xaml
