Butter Knife

View "injection" library for Android which uses annotation processing to generate code that does direct field assignment of your views.

class ExampleActivity extends Activity {
  @InjectView(R.id.title) TextView title;
  @InjectView(R.id.subtitle) TextView subtitle;
  @InjectView(R.id.footer) TextView footer;

  @Override public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_activity);
    Views.inject(this);
    // TODO Use "injected" views...
  }
}

For documentation and additional information see the website.

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