1.Download the latest JAR or grab via Maven
2.Gradle
compile 'com.jakewharton:butterknife:7.0.1'

Example

class ExampleActivity extends Activity {
  @Bind(R.id.user) EditText username;
  @Bind(R.id.pass) EditText password;

  @BindString(R.string.login_error)
  String loginErrorMessage;

  @OnClick(R.id.submit) void submit() {
    // TODO call server...
  }

  @Override public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_activity);
    ButterKnife.bind(this);
    // TODO Use fields...
  }
}

-----------------------------------------------

ButterKnife後，
讓Annotation單獨一行顯示，
不必再切成兩行，設定：

File > Settings > Editor > Code Style > Java > Filed annotations > Do not wrap after single annotation 打勾。
