配置：

1.在app下的build.gradle中添加apply和compile

      apply plugin: 'com.android.application'
      <strong>apply plugin: 'com.neenbedankt.android-apt'
      apply plugin: 'com.jakewharton.butterknife'</strong>
      android {
          compileSdkVersion 24
          buildToolsVersion "24.0.3"
          aaptOptions {
              cruncherEnabled = false
              useNewCruncher = false
          }
      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-v7:24.2.1'
          testCompile 'junit:junit:4.12'
         <strong>compile 'com.jakewharton:butterknife:8.4.0'
          apt 'com.jakewharton:butterknife-compiler:8.4.0'</strong>
      }
  
 

      buildscript {
          repositories {
              jcenter()
          }
          dependencies {
              classpath 'com.android.tools.build:gradle:2.2.0'
              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
      }
  
 

      class ExampleActivity extends Activity {
       @BindView(R.id.title) TextView title
        @BindView(R.id.subtitle) TextView subtitle;
        @BindView(R.id.footer) TextView footer;
        @Override public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.simple_activity);
          ButterKnife.bind(this);
          // TODO Use fields...
        }
      }
  
 

4.绑定Button，参数可选

      <span style="font-size:12px;">@OnClick(R.id.submit)
      public void submit(View view) {
        // TODO submit data to server...
      }</span>
  
 

      @OnClick(R.id.submit)
      public void submit() {
        // TODO submit data to server...
  
 

      static class ViewHolder {
          @BindView(R.id.title) TextView name;
          @BindView(R.id.job_title) TextView jobTitle;
          public ViewHolder(View view) {
            ButterKnife.bind(this, view);
          }
        }
  
 

      class ExampleActivity extends Activity {
      @BindString(R.string.title) String title;
      @BindDrawable(R.drawable.graphic) Drawable graphic;
      @BindColor(R.color.red) int red; // int or ColorStateList field
      @BindDimen(R.dimen.spacer) Float spacer; // int (for pixel size) or float (for exact value) field
        // ...
      }
  
 

      -keep class butterknife.** { *; }
      -dontwarn butterknife.internal.**
      -keep class **$$ViewBinder { *; }
      -keepclasseswithmembernames class * {
          @butterknife.* <fields>;
      }
      -keepclasseswithmembernames class * {
          @butterknife.* <methods>;
      }
