Example of an ads adapter allowing to hide ads.

AdmobAdapter.java

public class AdmobAdapter extends AbstractWrapAdapter<AdItem> {
    private static final int SPAN = 10;
    private boolean mShowAds = true;

    public AdmobAdapter() {
        super(Collections.singletonList(new AdItem()));
    }

    @Override
    public boolean shouldInsertItemAtPosition(int position) {
        return mShowAds && ((position + 1) % SPAN) == 0;
    }

    @Override
    public int itemInsertedBeforeCount(int position) {
        if(!mShowAds) return 0;
        return position/SPAN;
    }

    @Override
    public AdItem getItem(int position) {
        if (shouldInsertItemAtPosition(position)) {
            return getItems().get(0);
        }
        return null;
    }

    public void setShowAds(boolean show) {
        mShowAds = show;
        notifyDataSetChanged();
    }

}
