Question

我使用加载主题在Android应用上显示启动屏幕。在MainActivity中，我使用setTheme更改主题。当我在模拟器上从Android Studio构建应用程序时，它可以工作（它可以编译并运行）。当我尝试使用Build-> Build APKs构建APK时，出现错误。

E:\AndroidStudioProjects\gb\feature\src\main\java\com\zwsi\gb\feature\MainActivity.kt: (25, 20): Unresolved reference: style

构建APK与构建应用有什么不同？

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.perrochon.gb">

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme.Launcher">
        <meta-data
            android:name="aia-compat-api-min-version"
            android:value="1"/>
</application>
</manifest>

styles.xml

<resources>
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/app_background</item>
</style>

<style name="AppTheme.Launcher">
    <item name="android:windowBackground">@drawable/launch_background</item>
</style>

</resources>

MainActivity.kt

class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {

    setTheme(R.style.AppTheme) // TODO switch back from the Launcher Theme, but this won't compile to APK
    // setTheme(R.style.AppTheme) works in Android Studio -> Emulator, but not when building APKs. Error is
    // E:\AndroidStudioProjects\gb\feature\src\main\java\com\zwsi\gb\feature\MainActivity.kt: (25, 20): Unresolved reference: style

    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

编辑：添加构建gradle文件。我真的没有对Gradel构建文件做任何事情，这是Android Studio设置它们的方式。

来自gb的build.gradle

buildscript {
ext.kotlin_version = '1.2.71'
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

allprojects {
repositories {
    google()
    jcenter()
}
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

来自gb \ feature的build.gradle

我也有gblib目录，其中包含非Android代码的库。来自gb \ lib

的build.gradle

plugins {
    id 'org.jetbrains.kotlin.jvm'
}
apply plugin: 'java-library'

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
testImplementation 'junit:junit:4.12'
}

sourceCompatibility = "6"
targetCompatibility = "6"
repositories {
mavenCentral()
}
compileKotlin {
kotlinOptions {
    jvmTarget = "1.8"
}
}
compileTestKotlin {
kotlinOptions {
    jvmTarget = "1.8"
}
}

创建APK时setTheme（R.style.AppTheme）不起作用
