Show and Hide Floating Action Button when scrolling recyclerview

ShowHideFab.java

// Java
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);
        if (dy > 0 && fab.getVisibility() == View.VISIBLE) {
            fab.hide();
        } else if (dy < 0 && fab.getVisibility() != View.VISIBLE) {
            fab.show();
        }
    }
});

// Kotlin
recyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {
    override fun onScrolled(recyclerView: RecyclerView?, dx: Int, dy: Int) {
        super.onScrolled(recyclerView, dx, dy)
        if (dy > 0 && fab.visibility === View.VISIBLE) {
            fab.hide()
        } else if (dy < 0 && mFloatingActionButton.visibility !== View.VISIBLE) {
            fab.show()
        }
    }
})
