Finally I find it solution and I want to share with you.

You can enable/disable FloatingActionButton Behavior

Disable Behavior

    FloatingActionButton fab2 = (FloatingActionButton)findViewById(R.id.fab2);

    CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) fab2.getLayoutParams();
    params.setBehavior(null);
    fab2.requestLayout();
    fab2.setVisibility(View.GONE);

Enable Behavior

    CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) fab2.getLayoutParams();
    params.setBehavior(new QuickReturnFooterBehavior());
    fab2.requestLayout();
    fab2.setVisibility(View.VISIBLE);

Edited: More Reusable Class

public class CoordinateBehaviourUtils {

  public static void enableDisableViewBehaviour(View view,CoordinatorLayout.Behavior behavior,boolean enable){
    CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) view.getLayoutParams();
    params.setBehavior(behavior);
    view.requestLayout();
    view.setVisibility((enable ? View.VISIBLE: View.GONE));
  }

}

How To Enable Using Common Class

FloatingActionButton fab2 = (FloatingActionButton)findViewById(R.id.fab2);
CoordinateBehaviourUtils.enableDisableViewBehaviour(fab2,new QuickReturnFooterBehavior(),true);

How To Disable Using Common Class

FloatingActionButton fab2 = (FloatingActionButton)findViewById(R.id.fab2);
CoordinateBehaviourUtils.enableDisableViewBehaviour(fab2,null,false);

Hope it will solve your problem :)
