app 模块的build.gradle：

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'com.jakewharton.butterknife'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "com.example.liberty.hteach"
        minSdkVersion 15
        targetSdkVersion 24
        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(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.0.0'
    //    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
    compile 'com.android.support:design:24.0.0'
    compile 'com.jakewharton:butterknife:8.4.0'
    apt 'com.jakewharton:butterknife-compiler:8.4.0'

    testCompile 'junit:junit:4.12'
    compile 'com.android.support:support-annotations:24.0.0'
}

项目build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
//        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-rc2'
        classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'
        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()
    }
}

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

MainActivity:

public class MainActivity extends AppCompatActivity {

//    private TabLayout tabLayout;
//    private ViewPager viewPager;

    @BindView(R.id.viewPager)
    ViewPager viewPager;
    @BindView(R.id.tabs)
    TabLayout tabLayout;
    @BindArray(R.array.titles)
    String []titles;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
//        viewPager= (ViewPager) findViewById(R.id.viewPager);
//        tabLayout= (TabLayout) findViewById(R.id.tabs);
        ButterKnife.bind(this);
}
}

在新的8.4版本中去除了unbind方法

Unbinder mUnbinder;
@Override 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_activity);
     mUnbinder=ButterKnife.bind(this);  //保存引用
    ｝
@Override
  protected void onDestroy() {
     super.onDestroy();
    mUnbinder.unbind();  //释放所有绑定的view
  }
