java - Android @drawable/logos.png 报错logos.png is incompatible with attribute android :res

Question

我正要制作启动画面，我是在 VSCode 而不是 android studio 中制作的，因为我使用 flutter 作为 SDK。我手动导入了图像(拖放)并更改了 styles.xml 和 launch_background.xml 中的某些内容(因为它是初始屏幕)，但出现了此错误

E:\Git\kene\android\app\src\main\res\drawable\launch_background.xml: AAPT: error: '@drawable\logos.png' is incompatible with attribute android:src (attr) reference|color.

E:\Git\kene\android\app\src\main\res\drawable\launch_background.xml:0: error: '@drawable\logos,png' is incompatible with attribute android:src (attr) reference|color.
error: failed linking file resources.

这是我的 styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
    <!-- Show a splash screen on the activity. Automatically removed when
         Flutter draws its first frame -->
    <item name="android:windowBackground">@drawable/launch_background</item>
    <item name="android:windowFullscreen">true</item>
</style>
</resources>

这是我的 launch_background.xml

 <?xml version="1.0" encoding="utf-8"?>
   <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@android:color/white" />
    <!-- You can insert your own image assets here -->
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable\logos.png" />
    </item>
    </layer-list>

我可以确保文件名是正确的，文件位于/src/main/res/drawable

像这样从 launch_background.xml 中的文件名中删除 .png:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@android:color/white" />
<!-- You can insert your own image assets here -->
<item>
    <bitmap
        android:gravity="center"
        android:src="@drawable\logos" />
</item>
</layer-list>
