java AAPT:错误：未找到样式属性“安卓:attr/WindowsPlashCreenBackground”

Question

我也犯了同样的错误，使用Android Studio Canary

它在Gradle 4.2.1和Gradle最新版本7.1.0-alpha09中返回相同的错误。（即错误日志如下）

此外，我还更新了：

1. SDK平台到Android 12（S）
2. Plus SDK构建工具更新为Android SDK构建工具31

我必须在哪里/如何实现这些样式属性？ 我已将以下项目添加到样式中。xml

    <item name="安卓:windowBackground">@drawable/splash</item>
    <item name="安卓:windowSplashScreenBackground">@drawable/splash</item>
    <item name="安卓:windowSplashScreenAnimatedIcon">@null</item>

Answer 1

很可能是我的question的复制品

我猜你没有改变主题

在最新的更新中，安卓12附带了SplashScreen API，以确保启动屏幕从安卓12开始正确显示

要访问它，你必须升级你的gradle文件，并将你的主题父项更改为^{。在你的gradle中添加：

android {
    //before syncing please make sure Android API 12 is installed in SDK manager
    compileSdkVersion 31 
    ...
}
dependencies {
    ...
    implementation 'androidx.core:core-splashscreen:1.0.0-alpha01'
    ...
}

为启动屏幕创建一个单独的style.xml

<resources>
    <style name="Theme.MySplashScreen" parent="Theme.SplashScreen"> 
        <item name="windowSplashScreenBackground">@color/black</item> <!  If it's a @drawable make sure it's in .xml format >
        <item name="windowSplashScreenAnimationDuration">1000</item>
        <item name="windowSplashScreenAnimatedIcon">@drawable/books_logo</item>
        <item name="postSplashScreenTheme">@style/Theme.Books</item> <!  This will switch back to your given theme once the splash screen is gone >
    </style>
</resources>

在清单中设置主题<application>

<manifest>
   <application 
   ...
   android:theme="@style/Theme.MySplashScreen">
   ...

最后在MainActivity中，或者在setContentView()之前的onCreate()中设置启动屏幕的启动活动

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        installSplashScreen()

        setContentView(...)
}
