A floating action button represents the primary action in an application. A floating action button is used for a promoted action. Shaped like a circled icon floating above the UI, it changes color upon focus and lifts upon selection. When pressed, it may contain more related actions.

Add the Event Listener to FloatingActionButton:

FloatingActionButton myFab = (FloatingActionButton) myView.findViewById(R.id.myFAB); 
myFab.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
        doMyThing(); 
    } 
});
