Kotlin 学习地址总结

1 . 官网教程
2 . Anko GitHub
3 . Kotlin Resource

android studio 配置

1 . 当前项目的build.gradle

   ext.support_version = '23.1.1'//添加
   ext.kotlin_version = '1.0.4'//添加
   ext.anko_version = '0.10.1'//添加
   repositories {
      // jcenter() 更改为
   maven{ url 'http://maven.aliyun.com/nexus/content/groups/public'}
   }
   dependencies {
       classpath 'com.android.tools.build:gradle:2.3.1'
       classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"//添加
       // NOTE: Do not place your application dependencies here; they belong
       // in the individual module build.gradle files
   }
}

allprojects {
   repositories {
        // jcenter() 更改为
   maven{ url 'http://maven.aliyun.com/nexus/content/groups/public'}
       maven {url 'https://dl.bintray.com/jetbrains/anko'}//添加
   }
}

2 . module的build.gradle中的dependencies {}下添加以下依赖

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
    compile "com.android.support:appcompat-v7:$support_version"
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    compile "org.jetbrains.anko:anko-common:$anko_version"
    compile "org.jetbrains.anko:anko-appcompat-v7-listeners:$anko_version"
    compile "org.jetbrains.anko:anko-design-listeners:$anko_version"
    compile "org.jetbrains.anko:anko-design:$anko_version"
    compile "org.jetbrains.anko:anko-sdk15-listeners:$anko_version"
    compile "org.jetbrains.anko:anko-sdk15:$anko_version"
    compile "org.jetbrains.anko:anko-recyclerview-v7:$anko_version"

Kotlin问题

出现Gradle DSL not fund Method问题

    compile "org.jetbrains.anko:anko-recyclerview-v7:$anko_version"  compile 'com.android.support:appcompat-v7:25.3.1'

更改为：

    compile "org.jetbrains.anko:anko-recyclerview-v7:$anko_version"
    compile 'com.android.support:appcompat-v7:25.3.1'

不确定，为什么一定要换行才行？
切记切记！！！
compile "....$..."这个语法必须要buildtoolsVerision大于26.0.1才支持

关于build.gradle文件中一些变量解释

   compileSdkVersion 25 //当前编译的sdk
   buildToolsVersion "25.0.2"//构建工程包括 compile等等的工具 必须大于 compileSdkVersion
   defaultConfig {
       applicationId "adr.ycx.com.testsreen"
       minSdkVersion 21 //最低版本 lint在我们写代码时会提示当前api是否满足最低版本
       targetSdkVersion 25// 最高版本 一般来说要等于compileVersion 不能大于它
       versionCode 1
       versionName "1.0"

       testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

   }
