Question

    public class LoginActivity extends AppCompatActivity {

  @BindViews(value = {R.id.logo, R.id.first, R.id.second, R.id.last})

  @Override

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

    for (ImageView element : sharedElements) {

Answer 1

First remove 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);

Second add this:

    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 
        }

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

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.

Try and reply how is it going.
