butterknife

1 . 工程build.gradle下粗体配置

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'  
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

2. app build.gradle下配置 粗体

apply plugin: 'android-apt'   同样要写

dependencies {

    compile 'com.jakewharton:butterknife:8.1.0'
    apt 'com.jakewharton:butterknife-compiler:8.1.0'
    compile 'de.greenrobot:greendao:2.0.0'
}
