and on onCreateView check like this

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent,
    Bundle savedInstanceState) 
{
  if (savedInstanceState != null) 
  {
    if (savedInstanceState.containsKey(ANSWER_ONE_BUTTON_ISCLICKED))
    {
      if (savedInstanceState.getBoolean(ANSWER_ONE_BUTTON_ISCLICKED))
        button.setBackgroundResource(R.drawable.button_red);
      else
        button.setBackgroundResource(R.drawable.original_color);
    }
     //some codes to make the button becomes clicked.
  }
}
