@BindView(R.id.text_input) 
TextView text_input; 

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

@Override 
public void onActivityCreated(@Nullable Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 

    text_input.setText("Hello Lima, Perú");
