Flutter 更改闪屏背景颜色

Question

我的launch_background.xml文件中有这个默认代码：

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<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="@mipmap/ic_launcher" />
    </item>
</layer-list>

我只想知道，如何将其更改<item android:drawable="@android:color/white" />为自定义颜色，例如<item android:drawable="@android:color/#FFF8DC" />

Answer 1

创建文件 android/app/src/main/res/values/colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <color name="red">#FF0000</color>
</resources>

编辑 android/app/src/main/res/drawable/launch_background.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/red" />

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

Answer 2

colors.xml在您的app/src/main/res/values文件夹中创建文件并在该文件中写入

<color name="yourColor">#FFF8DC </color>

然后在你的launch_background.xml文件中使用它，

<item android:drawable="@color/yourColor" />
