FloatingActionButton doesn't hide

Question

I am trying to hide my FloatingActionButton fabLocation programmatically with :

fabLocation.setVisibility(View.GONE)

but it do

Answer 1

I worked around the show()/hide() shortcoming by placing the FAB in or out of the screen using layout margins. example:

CoordinatorLayout.LayoutParams p =
   new CoordinatorLayout.LayoutParams(
      CoordinatorLayout.LayoutParams.WRAP_CONTENT,
      CoordinatorLayout.LayoutParams.WRAP_CONTENT);

p.gravity = Gravity.BOTTOM | Gravity.LEFT;
int fabMargin = (int)res.getDimension(R.dimen.fab_margin);

if( enabled ) {
   p.setMargins(fabMargin,0,0,fabMargin);
}
else {
   p.setMargins(-200,0,0,fabMargin);
}
mFab.setLayoutParams(p);
