Answer 1

You can use something similar to this example from the ButterKnife docs:

You can also perform binding on arbitrary objects by supplying your own view root.

public class FancyFragment extends Fragment {
  @BindView(R.id.button1) Button button1;
  @BindView(R.id.button2) Button button2;

  @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fancy_fragment, container, false);
    ButterKnife.bind(this, view);
    // TODO Use fields...
    return view;
  }
}

The class which you pass as the first argument to ButterKnife.bind() must have fields that are annotated with @BindView. The most straightforward way to do this is to create a custom View class called ListViewHeader or something more specific to your use.
