9 Butterknife

Butterknife is a annotation processing-based library for Android for Field and method binding. It replaces the findViewById()-methods inside your Activities or Fragments by simple annotations (@BindView) to create generated classed for the view injection. It also eliminates anonymous inner-classes for listeners by using the @OnClick annotation.

To inject the views you need to call ButterKnife.bind(this) in your onCreate method. You should store a private instance of this binder in your class to call unbind() in the onDestroyView method of your Fragment / or Activity.
