fab 隐藏后不显示

Currently CoordinatorLayout is skipping views set to GONE when looking for behaviours to call in its onNestedScroll method.
A quick workaround here is setting the FAB’s visibility to INVISIBLE at the end of the FAB’s hide animation.

if(dyConsumed>0&&child.getVisibility()==View.VISIBLE) {
	child.hide(new FloatingActionButton.OnVisibilityChangedListener() {
		@Override
    	public void onHidden(FloatingActionButton fab) {
			super.onHidden(fab);
			fab.setVisibility(View.INVISIBLE);
		}
	});
}else if(dyConsumed<0&&child.getVisibility()!=View.VISIBLE){
	child.show();
}
