Android Butterknife - 在 fragment 中绑定(bind)

Question

我是第一次使用 Butterknife，但肯定有问题。我有一个 fragment 、一个 Listview 和一个 TextView 仅用于测试，但 Butterknife 不会绑定(bind)我的变量:

public class MyFragment extends Fragment {

    @Bind(R.id.resultListView) ListView resultList;

    @Bind(R.id.textView1) TextView test;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my, container, false);
        ButterKnife.bind(this, view);
        System.out.println(resultList); //null
        System.out.println(view.findViewById(R.id.resultListView)); //works
        System.out.println(test); //null
        System.out.println(view.findViewById(R.id.textView1)); //works
        return view;
    }

}

没有异常(exception)或任何事情。手动绑定(bind)有效，所以我的 View 必须在那里。

这对我有用:

annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0'

代码

...

@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("Lorem Ipsum");
