Butter Knife

Field and method binding for Android views which uses annotation processing to generate boilerplate code for you.

Eliminate findViewById calls by using @BindView on fields.
Group multiple views in a list or array. Operate on all of them at once with actions, setters, or properties.
Eliminate anonymous inner-classes for listeners by annotating methods with @OnClick and others.
Eliminate resource lookups by using resource annotations on fields.

class ExampleActivity extends Activity {
  @BindView(R.id.user) EditText username;
  @BindView(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...
  }
}

Remember: A butter knife is like a dagger only infinitely less sharp.
