Android Butterknife - 在片段中綁定

Question

我第一次使用Butterknife，但一定是錯誤的。我有一個片段和列表視圖和一個TextView只是用於測試，但Butterknife不會綁定我的變量：

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; 
    } 

} 

沒有異常或任何東西。手動綁定的作品，所以我的意見必須在那裏。

Answer 1

代碼是聰明的，看起來只有精細。因此，基於的評論，它看起來像你需要設置Eclipse中的批註處理：http://jakewharton.github.io/butterknife/ide-eclipse.html

Answer 2

這項工作對我來說：

搖籃

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

代碼

... 

@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"); 
...

也不要忘了釋放，當你完成：

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(); 
    }
