無法獲得基本的漢堡包詳細信息視圖

Question

查看所有問題和論壇後，我仍無法使用漢堡圖標獲取我的主詳細信息頁面。如果我使用這個主細節頁作爲應用程序啓動，那麼我看到功能按預期工作。請看下面的代碼

DashBoadCreator.xaml `

<MasterDetailPage.Master> 

</MasterDetailPage.Master> 

<MasterDetailPage.Detail> 

    </x:Arguments> 
</NavigationPage> 
</MasterDetailPage.Detail> 
` 

`public partial class DashBoadCreator : MasterDetailPage 
{ 
DashboardMaster master; 
DashboardDetail1 detil; 
public DashBoadCreator() 
{ 
InitializeComponent(); 
master = new DashboardMaster(); 
detil = new DashboardDetail1(); 

     Master = master; 
     Master.Title = "this is a title"; 
     Master.Icon = "icon.png"; 
     Detail = new NavigationPage(detil); 

    } 

    // Event for Menu Item selection, here we are going to handle navigation based 
    // on user selection in menu ListView 

}` 
DashboadMaster.xaml

Answer 1

一些調查後，我來到accorss討論

Missing menu button on MasterDetailPage when assigning App.MainPage

使用這些發現我改變了我的app.xaml.cs如下

MainPage = new NavigationPage(new MenuPage()); 
MasterDetailTest.App.Current.MainPage.Navigation.PushAsync(new MainPage()); 

現在的母版頁始終是根頁面和漢堡包菜單按預期工作。對於有這個問題的其他人希望這可以幫助你以某種方式

Answer 2

集圖標母版頁看到hambu rger圖標

示例代碼：

public masterpage() 
{ 
    Icon = "hamburger.png"; 
}
