How to enable/disable FloatingActionButton Behavior

Question

I am working on app in some fragment i want to hide FloatingActionButtton. When i set android:visibility=\"gone\". Behavior animation show me FloatingAction

Answer 1

In kotlin enable/disable is:

fab.isEnabled = true
fab.isEnabled = false

Answer 2

There is no difference while setting up the visibility of a FAB, it works likely other controls.

0 is for VISIBLE
4 is for INVISIBLE
8 is for GONE

You can try something this;

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
// to make is disable for some requirement 
fab.setVisibility(View.GONE);
// to make it enable 
fab.setVisibility(View.VISIBLE);

Answer 3

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<View> 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 :)
