To clear the shared preference you need to add this code.

SharedPreferences.Editor.clear();
SharedPreferences.Editor.commit();

Try the following code. It will clear your SharedPreferences.

     SharedPreferences pref = getActivity().getSharedPreferences(
             "mypassword", getActivity().MODE_PRIVATE);
     Editor editor = pref.edit();
     editor.clear(); 
     editor.commit();

This should be used -

SharedPreferences settings = view.getContext().getSharedPreferences("mypassword", 0);
SharedPreferences.Editor editor = settings.edit();
editor.clear();
editor.commit();

Try:

Editor e = pref.edit();
e.remove("key_username");
e.remove("key_password");
e.commit();
