I'm trying to hide and show part of my view in my PagerAdapter item but it doesn't do anything, not GONE, VISIBLE, or INVISIBLE.

public class FeedPagerAdapter extends PagerAdapter {
    private final String KEY_GLOBAL_PREFS = "global";

    @BindView(R.id.item) ImageView image;
    @BindView(R.id.progress_bar) ProgressBar progressBar;

    private final SlideActivity host;
    private List<Thing> items;

    private SharedPreferences sharedPreferences;

    private int postition;

    public FeedPagerAdapter(SlideActivity host, List<Thing> items){
        this.host = host;
        this.items = items;

        sharedPreferences = host.getSharedPreferences(KEY_GLOBAL_PREFS, Context.MODE_PRIVATE);
    }

    @Override
    public Object instantiateItem(final ViewGroup parent, int position) {
        final View view = LayoutInflater.from(host).inflate(R.layout.item_slide_reddit_post, parent, false);
        ButterKnife.bind(this, view);

        progressBar.setVisibility(View.GONE);

        return view;
    }

    @Override
    public int getCount() {
        return items.size();
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View)object);
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }
}

Here's the item xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/item"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src:"..."/>
    <ProgressBar
        android:id="@+id/progress_bar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

And here is how the adapter is set up from the host activity:

adapter = new FeedPagerAdapter(SlideActivity.this, List<> of items);
viewPager.setAdapter(adapter);
viewPager.setCurrentItem(position);
adapter.notifyDataSetChanged();

Any help would be awesome
