Android Butterknife - 片段绑定

我第一次使用Butterknife,但一定是错的.我有一个片段,Listview和TextView只是为了测试,但Butterknife不会绑定我的变量:

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;
    }

}

没有例外或任何事情.手动绑定有效,所以我的意见必须在那里.

这项工作对我来说:

摇篮

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

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");
...
.

代码方面,看起来很好.所以基于这些注释,看起来你需要在Eclipse中设置注释处理:http://jakewharton.github.io/butterknife/ide-eclipse.html

当你完成时也不要忘记释放:

 private Unbinder unbinder;

...

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.finalisation_step_fragment, container, false);
        unbinder = ButterKnife.bind(this, v);
        //initialize your UI

        return v;
    }

...

   @Override public void onDestroyView() {
        super.onDestroyView();
        unbinder.unbind();
    }
