带有选项卡式主页 Xamarin 表单的启动画面 [英] Splash screen with Tabbed main page Xamarin forms

问题描述

我是移动应用开发的初学者，我正在使用 Xamarin 表单为项目开发 Android 应用.

在我的 Xamarin 表单项目中，我必须在启动时添加启动画面.为此，我必须将此代码放在 MainPage.XAML

<!-- 在此处放置新控件--><Label Text="欢迎使用 Xamarin.Forms！"水平选项=中心"VerticalOptions="CenterAndExpand"/><Grid x:Name="SplashGrid" BackgroundColor="{StaticResource Primary}"><Image x:Name="Logo" Source="Logo" Horizo​​ntalOptions="Center" VerticalOptions="Center"><Image.TranslationY><OnPlatform x:TypeArguments="x:Double"><On Platform="Android">-12</On></OnPlatform></Image.TranslationY></图片></网格></网格>

但我的主页是标签页而不是内容页.

当我的主页保持选项卡状态时，我可以做些什么来实现启动画面?

如果我的标签页可以在加载主页面后自动打开，那也不错.

这是我的 App.xaml.cs 的构造函数的样子.

公共应用程序(){初始化组件();MainPage = new NavigationPage(new TabbedPageContainer());}

非常感谢您的帮助.提前致谢.

解决方案

通常，我们使用可绘制资源来创建启动画面.按照以下步骤操作.

I'm a beginner in mobile app development and I'm developing an android app using Xamarin forms for a project.

On my Xamarin forms project, I have to add a splash screen at startup. to accomplish this I have to put this code on my MainPage.XAML

<Grid>
        <!-- Place new controls here -->
        <Label Text="Welcome to Xamarin.Forms!" 
           HorizontalOptions="Center"
           VerticalOptions="CenterAndExpand" />

        <Grid x:Name="SplashGrid" BackgroundColor="{StaticResource Primary}">
            <Image x:Name="Logo" Source="Logo" HorizontalOptions="Center" VerticalOptions="Center">
                <Image.TranslationY>
                    <OnPlatform x:TypeArguments="x:Double">
                        <On Platform="Android">-12</On>
                    </OnPlatform>
                </Image.TranslationY>
            </Image>
        </Grid>
    </Grid>

But my main page is a Tabbed page and not a content page.

What can I do to achieve a splash screen while my main page remains tabbed?

if my tabbed page can be opened automatically after loading the main page, that would be fine too.

this is how the constructor of my App.xaml.cs looks.

public App()
        {
            InitializeComponent();
            MainPage = new NavigationPage(new TabbedPageContainer()); 
        }

I really appreciate your help. Thanks in advance.

解决方案

Normally, we use drawable resource to create the splash screen. Follow the stpes below.

You could follow the stpes on the link below. It works well on tabbed page. Xamarin forms custom splash screen
