AndroidStudio 使用Lambada 以及相互转化

A gradle plugin for getting java lambda support in java 6, 7 and android

根目录build.gradle 加入tataka地址

dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
classpath 'me.tatarka:gradle-retrolambda:3.2.5'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}

app目录build.gradle

加入apply plugin: ‘me.tatarka.retrolambda’

android{
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:2.3.0'
}

重点说一下 相互转化：

光标移动到在lambada语句上Alt+Enter

选择 replace lambada with annoymous class 反之也可以
