经历了无数深坑，网上的帖子都是8.0.0+，尝试了各种方案无果，最后看到大佬的帖子才配置成功，特此记录。

可以直接移步原贴，也可以看下去，????[原贴地址 ][Link 1]

# 一、配置 #

首先说一下我的android studio和gradle版本：

android studio 3.4

gradle版本 3.4.1

主要做了以下配置

在App的build.gradle中的dependencies中添加下面两行：

implementation 'com.jakewharton:butterknife:9.0.0-SNAPSHOT'
    annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT'

在Module的build.gradle中的buildscript以及allprojects中添加

maven { url "https://oss.sonatype.org/content/repositories/snapshots" }

然后Sync now就完成配置了，直接把两个build.gradle贴出来，可以参考

apply plugin: 'com.android.application'
    //apply plugin: 'com.android.library'
    //apply plugin: 'com.jakewharton.butterknife'
    android {
        compileSdkVersion 28
        defaultConfig {
            applicationId "com.example.hello"
            minSdkVersion 28
            targetSdkVersion 28
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            }
        }
        compileOptions {
           sourceCompatibility JavaVersion.VERSION_1_8
            targetCompatibility JavaVersion.VERSION_1_8
        }
    }
    
    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:28.0.0'
        implementation 'com.android.support.constraint:constraint-layout:1.1.3'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test:runner:1.0.2'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
        implementation 'com.android.support:gridlayout-v7:28.0.0'
    
        /*implementation 'com.jakewharton:butterknife:9.0.0'
        annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0'*/
        //noinspection GradleDependency
        implementation 'com.jakewharton:butterknife:9.0.0-SNAPSHOT'
        //noinspection GradleDependency
        annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT'
    
    }

// Top-level build file where you can add configuration options common to all sub-projects/modules.
    
    buildscript {
        repositories {
            google()
            jcenter()
            maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.4.1'
            classpath 'com.jakewharton:butterknife-gradle-plugin:9.0.0'
            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }
    
    allprojects {
        repositories {
            google()
            jcenter()
            maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
        }
    }
    
    task clean(type: Delete) {
        delete rootProject.buildDir
    }

# 二、测试 #

在一个页面中加一个button2，通过@BindView来绑定一个button，然后设置它的点击事件，可以不用写成匿名内部类的形式，直接使用@OnClick绑定点击事件函数即可，下面实现的就是点击一个按钮，弹出消息框，提示“点击事件绑定成功”。

public class AnotherActivity extends Activity {
        @BindView(R.id.button2) Button btn2; //绑定button2
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_another);
            ButterKnife.bind(this);
            Button button = findViewById(R.id.button);
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    finish();
                }
            });
    
    
        }
        @OnClick(R.id.button2)   //button2的点击事件
        public void onBtn2Click(){
            Toast.makeText(AnotherActivity.this, "点击事件绑定成功", Toast.LENGTH_SHORT).show();
        }
    }
