无法在局部变量“@BindViews"中使用不适用于局部变量黄油刀

问题描述

    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));
    }

请帮我用 butterknife 修复这个错误.findbyid 也不可用无法使用 bindview 请帮助文档或您的代码.所以这就是 authFragment 在按照 GermliShx 的建议进行一些更改之后，这些错误可能是我的实现错误，所以请帮助我.这是登录页面，带有一些动画 idk y butterknife 正在制造问题.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现所以请帮助我

推荐答案

先去掉这个:

    @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.

Should work, but I am not sure what AnimatedViewPager is.

它也可能显示Resource IDs will be non-final in Android Gradle Plugin version 7.0，避免将它们用作注释属性警告，但您可以取消它.

It also may show Resource IDs will be non-final in Android Gradle Plugin version 7.0, avoid using them as annotation attributes warning, but you can just suppress it.

尝试回复情况如何.
