延迟应用的启动屏幕不应该，因为它们会阻止用户使用您的应用做任何事情。

但是：有一种更好的方法，它更容易实现！每个应用程序都需要一些时间来启动，并且在启动时，大多数应用程序仅显示白色背景，因为这是默认设置。您可以通过向themes.xml添加一个将windowBackground设置为任何可绘制

的新样式来更改它

<style name="YourApp.AppTheme.Splashscreen" parent="YourApplicationsTheme">
    <item name="android:windowBackground">@drawable/splashscreen</item>
</style>

如果您想在彩色背景上添加徽标，可以像这样定义可绘制的内容：

<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:opacity="opaque">
    <item android:drawable="@color/some_color"/>
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/some_logo"/>
    </item>
</layer-list>

只需将此主题添加到<application>中的AndroidManifest.xml，您的启动画面就已启动并正常运行。

最后，在启动后使用

将主题设置回正常主题

getApplication().setTheme(R.style.YourApplicationsTheme);

以防止在切换活动时出现飞溅。

全部完成！美丽的闪屏，不会延迟用户。

Android设计指南也建议that way，您也可以参考this作为参考。

检查布局文件。确保使用正确的布局文件。在java代码中，您使用了content_splash_screen.xml，但是，您已经发布了splash.xml的代码。

代码中没有错误，您的代码应运行正常。
