I managed it by adding the following implementation of OnOffsetChangedListener in fragment:

@Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {

    appBarLayout.addOnOffsetChangedListener(this);
}

@Override
public void onPause() {
    super.onPause();
    appBarLayout.removeOnOffsetChangedListener(this);
}
