Android 新建项目找不到R文件导入

1、Android 新创建的项目找不到R文件。

2、解决方式：

在项目的XML文件中添加

注意：这个就能解决问题了，如果不能解决，下方的对齐一下。

3、gradle也要同步一下

1、全局的build.gradle

buildscript {
    //1.4.10
    ext{
        kotlin_version = '1.6.10'
    }
    repositories {
        google()
        mavenCentral()
        //阿里云jcenter仓库
        maven{ url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
            url 'https://jitpack.io'
        }
    }
    dependencies {
        //4.1.1
        classpath 'com.android.tools.build:gradle:4.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
    }

}


allprojects {
    repositories {
        google()
        mavenCentral()
        //阿里云jcenter仓库
        maven{ url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
            url 'https://jitpack.io'
        }
    }
    //配置这个
    tasks.withType(Javadoc) {
        options.addStringOption('Xdoclint:none', '-quiet')
        options.addStringOption('encoding', 'UTF-8')
    }
}

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

2、gradle-wrapper.properties

#Mon Nov 20 13:48:45 CST 2023
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

3、app的build.gradle

buildscript {
    //1.4.10
    ext{
        kotlin_version = '1.6.10'
    }
    repositories {
        google()
        mavenCentral()
        //阿里云jcenter仓库
        maven{ url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
            url 'https://jitpack.io'
        }
    }
    dependencies {
        //4.1.1
        classpath 'com.android.tools.build:gradle:4.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'
    }

}


allprojects {
    repositories {
        google()
        mavenCentral()
        //阿里云jcenter仓库
        maven{ url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
            url 'https://jitpack.io'
        }
    }
    //配置这个
    tasks.withType(Javadoc) {
        options.addStringOption('Xdoclint:none', '-quiet')
        options.addStringOption('encoding', 'UTF-8')
    }
}

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