Flutter 启动画面不适用于 launch_background.xml

如何解决Flutter 启动画面不适用于 launch_background.xml

我似乎无法显示我自己的启动画面，每次启动应用程序时都会显示默认的空白启动画面，即使我已经在 launch_background.xml 中设置了所有内容并在 {{ 中设置了其他文件1}}。我还在 res 和 drawable 中设置了所有相关图标。

launch_background.xml：

mipmap

styles.xml:

<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <color android:color="@color/splash" />
    </item>

    <!-- You can insert your own image assets here -->
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/splash_icon" />
    </item>
</layer-list>

colors.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- Theme applied to the Android Window while the process is starting when the OS's Dark Mode setting is off -->
    <style name="LaunchTheme" parent="@android:style/Theme.Light.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
    <!-- Theme applied to the Android Window as soon as the process has started.
         This theme determines the color of the Android Window while your
         Flutter UI initializes,as well as behind your Flutter UI while its
         running.
         
         This Theme is only used starting with V2 of Flutter's Android embedding. -->
    <style name="normalTheme" parent="@android:style/Theme.Light.NoTitleBar">
        <item name="android:windowBackground">?android:colorBackground</item>
    </style>
</resources>

AndroidManifest.xml 中的

<?xml version="1.0" encoding="utf-8"?> <resources> <color name="ic_launcher_background">#191919</color> <color name="splash">#191919</color> </resources> 标记：

<activity>

初始屏幕应该显示一个图像和不同的背景颜色，但它只显示默认的空白屏幕。我没有为此使用自定义启动画面。我只想至少改变颜色，但即使这样也行不通。

解决方法

还要在 drawable-v21/launch_background.xml 中进行更改。这将用于 Android API 级别 21 或更高级别。
