Questions tagged [butterknife]

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.

Android: Why do we need to use R2 instead of R with butterknife?

I've been using butterknife for a few months and I've just noticed in its documentation that it says: Now make sure you use R2 instead of R inside all Butter Knife annotations. Why is that? I've been using R and everything works perfect.
