How to use implement the listener in Activity for click on Add Flab?

Sorry for the late response. It depends on which floating action button you want to attach a click listener to:

• If you want a click listener for the normal FABs, just add a View.OnClickListener as you would normally do for any other button:

  View.OnClickListener listener = new View.OnClickListener() {
      @Override
      public void onClick(View view) {
          // called when the button is clicked
      }
  };
  FloatingActionButton button = findViewById(R.id.fab);
  button.setOnClickListener(listener);

• If you want a click listener for the main FAB, you can use the FloatingActionMenu.OnFloatingActionsMenuUpdateListener which gets called when the user toggles the menu:

  FloatingActionMenu.OnFloatingActionsMenuUpdateListener listener = new FloatingActionMenu.OnFloatingActionsMenuUpdateListener() {
      @Override
      public void onMenuExpanded() {
          // called when the menu has been expanded
      }
  
      @Override
      public void onMenuCollapsed() {
          // called when menu has been collapsed
      }
  }
  FloatingActionMenu menu = findViewById(R.id.fam);
  menu.setOnFloatingActionsMenuUpdateListener(listener);

• If you really need full control over the click listener for the main FAB, you can just set your own View.OnClickListener and toggle the menu there:

  final FloatingActionMenu menu = findViewById(R.id.fam);
  View.OnClickListener listener = new View.OnClickListener() {
      @Override
      public void onClick(View view) {
          // called when the main button is clicked
          menu.toggle();
      }
  };
  FloatingActionButton main = findViewById(R.id.fab_main);
  main.setOnClickListener(listener);
