Question

我有一个用Java编写的Android应用程序，但我想将其转换为Kotlin。我添加了Kotlin插件并配置了应用程序的gradle。

buildscript {
    ext.kotlin_version = '1.1.4-3'
dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}


apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}

我正在使用 - code - ＆gt;将单个文件从Java转换为Kotlin。将java文件转换为kotlin

转换后我收到此错误：
