Android design library 25.1.0 causes FloatingActionButton.Behavior to stop working

Question

I\'ve been using this FloatingActionButton.Behavior for many months now, it takes care of hiding and showing the FAB of my application. Never had an issue.

Answer 1

For 25.1.0, CoordinatorLayout is skipping views set to GONE when looking for behaviors to call in its onNestedScroll method.
The solution is replacing FAB's visibility GONE with INVISIBLE.
Simply, change:

child.hide();  

to:

child.hide(new FloatingActionButton.OnVisibilityChangedListener() {
        @Override
        public void onHidden(FloatingActionButton fab) {
            super.onHidden(fab);
            fab.setVisibility(View.INVISIBLE);
        }
    });
