xamarin.forms如何在標題欄中顯示視圖

如何在MasterDetailView的標題欄中放置視圖？我想盡可能使用xaml。xamarin.forms如何在標題欄中顯示視圖

我想要一個靜態標題視圖，我可以向用戶顯示各種統計信息。

        IsGestureEnabled="True" 
        MasterBehavior="Popover" 
        Title="Master Detail View"> 
    <MasterDetailPage.Master> 
    </MasterDetailPage.Master> 
    <MasterDetailPage.Detail> 
    </MasterDetailPage.Detail> 
</MasterDetailPage>

    <StackLayout Orientation="Vertical"> 
     <Label Text="{Binding Item1}"/>

       Command="{Binding OptionsCommand}" />

你可以」將標題視圖設置爲框w沒有擴展XF和編寫自定義渲染器，但是您可以將圖像設置爲頁面標題（如果頁面包含在NavigationPage中，則使用NavigationPage.TitleIconProperty

var page = new Page1View(); 
NavigationPage.SetIconTitle(page, "foo.png");
