无法在局部变量“@BindViews”中使用不适用于局部变量黄油刀

Question

    public class LoginActivity extends AppCompatActivity {

  @BindViews(value = {R.id.logo, R.id.first, R.id.second, R.id.last})
  protected List<ImageView> sharedElements;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    ButterKnife.bind(this);
    @BindViews({R.id.pager)

    @BindViews(R.id.scrolling_background)
    final AnimatedViewPager pager = ButterKnife.findById(this, R.id.pager);
    final ImageView background = ButterKnife.findById(this, R.id.scrolling_background);
    int[] screenSize = screenSize();

    for (ImageView element : sharedElements) {
      @ColorRes int color = element.getId() != R.id.logo ? R.color.white_transparent : R.color.color_logo_log_in;
      DrawableCompat.setTint(element.getDrawable(), ContextCompat.getColor(this, color));
    }

验证片段

{
    public abstract class AuthFragment extends Fragment {
      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    
      }
      protected Callback callback;
    
      @BindView(R.id.caption)
      protected VerticalTextView caption;
    
      @BindView(R.id.root)
      protected ViewGroup parent;
    
      protected boolean lock;
    
    
    
      @Nullable
      @Override
      public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View root = inflater.inflate(authLayout(), container, false);
        ButterKnife.bind(this, root);
        KeyboardVisibilityEvent.setEventListener(getActivity(), isOpen -> {
          callback.scale(isOpen);
          if (!isOpen) {
            clearFocus();
          }
        });
        return root;
      }
    
      public void setCallback(@NonNull Callback callback) {
        this.callback = callback;
      }
    
      @LayoutRes
      public abstract int authLayout();
    
      public abstract void fold();
    
      public abstract void clearFocus();
    
      @OnClick(R.id.root)
      public void unfold() {
        if (!lock) {
          caption.setVerticalText(false);
          caption.requestLayout();
          Rotate transition = new Rotate();
          transition.setStartAngle(-90f);
          transition.setEndAngle(0f);
          transition.addTarget(caption);
          TransitionSet set = new TransitionSet();
          set.setDuration(getResources().getInteger(R.integer.duration));
          ChangeBounds changeBounds = new ChangeBounds();
          set.addTransition(changeBounds);
          set.addTransition(transition);
          TextSizeTransition sizeTransition = new TextSizeTransition();
          sizeTransition.addTarget(caption);
          set.addTransition(sizeTransition);
          set.setOrdering(TransitionSet.ORDERING_TOGETHER);
          caption.post(() -> {
            TransitionManager.beginDelayedTransition(parent, set);
            } 

请帮我用黄油刀修复这个错误。 findbyid 也不可用，无法使用 bindview 请帮助提供文档或代码。因此，在 GermliShx 建议的一些更改之后，现在就是 authFragment 这些错误可能是我的实现错误，所以请帮助我。这是带有一些动画的登录页面，idk y butterknife 正在给她制造问题。我尝试解决它但没有运气这个错误是由于黄油刀的错误实施所以请帮帮我

Answer 1

首先删除这个：

    @BindViews({R.id.pager)
    @BindViews(R.id.scrolling_background)
... 
final AnimatedViewPager pager = ButterKnife.findById(this, R.id.pager);
    final ImageView background = ButterKnife.findById(this, R.id.scrolling_background);

第二次添加：

    public class LoginActivity extends AppCompatActivity {
        ...
       //binding is declared outside OnCreate / any other function

       //your case
        @BindView(R.id.pager)
            AnimatedViewPager pager;
            @BindView(R.id.scrolling_background)
            ImageView background ;

        ..
        //then in code just use declared pager and background when needed 
         @Override
          protected void onCreate(Bundle savedInstanceState) {
              background .setColorFilter (R.color.black); //example 
        }

应该可以，但我不确定 AnimatedViewPager 是什么。

它也可能显示Resource IDs will be non-final in Android Gradle Plugin version 7.0, avoid using them as annotation attributes 警告，但您可以直接取消它。

尝试并回复进展如何。
