為了碼代碼的效率，我們有了ButterKnife;其基本使用如下步驟：

1.在Android Studio的Setting中，下載plugin

2.在整個工程的build.gradle中添加butterknife依賴

buildscript {
    repositories {
        jcenter()
        maven{ url "https://jitpack.io" }
    }
    dependencies {
        classpath ‘com.android.tools.build:gradle:2.2.2‘
        //這裏配置 apt 供butterknife使用
 

        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
    }
}

allprojects {
    repositories {
        jcenter()

        maven { url "https://jitpack.io" }
    }
}

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

3.在你要使用的module中添加butterknife的依賴

apply plugin: ‘com.android.application‘
apply plugin: ‘com.neenbedankt.android-apt‘

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.lemon.livecircledemo"
        minSdkVersion 21
        targetSdkVersion 
 
25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘
        }
    }
}

dependencies {
    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])
    androidTestCompile(‘com.android.support.test.espresso:espresso-core:2.2.2‘, {
        exclude group: ‘com.android.support‘, module: ‘support-annotations‘
    })
    compile ‘com.android.support:appcompat-v7:25.3.1‘
    testCompile ‘junit:junit:4.12‘

    compile ‘com.android.support:design:25.1.0‘
    //視圖綁定 butterknife
    compile ‘com.jakewharton:butterknife:8.4.0‘
    apt ‘com.jakewharton:butterknife-compiler:8.4.0‘
    compile ‘de.greenrobot:eventbus:3.0.0-beta1‘
    //引入okhttp
    compile ‘com.squareup.okhttp3:okhttp:3.5.0‘
    //引入retrofit
    compile ‘com.squareup.retrofit2:retrofit:2.1.0‘
    //引入rxjava
    compile ‘io.reactivex.rxjava2:rxjava:2.0.4‘
    //引入Log攔截器，方便DEBUG模式輸出log信息
    compile ‘com.squareup.okhttp3:logging-interceptor:3.5.0‘
    //引入rxjava適配器，方便rxjava與retrofit的結合
    compile ‘com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0‘
    //引入json轉換器，方便將返回的數據轉換為json格式
    compile ‘com.squareup.retrofit2:converter-gson:2.1.0‘
    //引入rxandroid
    compile ‘io.reactivex.rxjava2:rxandroid:2.0.1‘
    compile ‘com.github.bumptech.glide:glide:3.7.0‘
    compile ‘com.android.support:cardview-v7:25.1.0‘
    compile ‘com.android.support:recyclerview-v7:25.1.0‘
    compile ‘com.github.Aspsine:IRecyclerView:0.0.5‘

}

4.在你的setContentView()中，選中布局，右鍵Generator，在代碼中自動生成相關的視圖綁定。
