View (fabIcon) background can not be changed inside its onClickListener

Issue

I have the following fab Icon but when i click it, the button's background doesn't change into save Icon.

  fabEditAttendance = (FloatingActionButton) findViewById(R.id.fab_attendance_edit);

            fabEditAttendance.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                   fabEditAttendance.setBackgroundResource(android.R.drawable.ic_menu_save);

                    }
                }
            });

Solution

Solved : i had to use

 setImageResource(int resID);

not

setbackgroundResource(int resID); 

Solution Looks like this :

fabEditAttendance.setImageResource(android.R.drawable.ic_menu_save);
