An annotation-based Android view "injection" framework aimed at reducing boilerplate.

View "injection" library for Android which uses annotation processing to generate boilerplate code for you.

  • Eliminate findViewById calls by using @Bind on fields.
  • Group multiple views in a list using @BindViews. 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.

The documentation includes additional code examples and use cases.
