Support injection for createViewHolder

[jaychang0917]

The plugin doesn't work for the following code. What I want is to generate a ViewHolder class.

@Override
  public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
   // doesn't show "Generate Butterknife Injection"
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.cell_contributor, viewGroup, false);
    return new ViewHolder(view);
  }
