android - Shared preferences on fragment -

-

i trying use shared preferences on android inside fragment appcompat. says me "the method getdefaultsharedpreferences(context) in type preferencemanager not applicable arguments (preferenciasfragment)" here code:

private void savepreferences(string key, string value) {              sharedpreferences sharedpreferences = preferencemanager.getdefaultsharedpreferences(this);             editor editor = sharedpreferences.edit();             editor.putstring(key, value);             editor.commit();          }

try this..

use getactivity() instead of this

sharedpreferences sharedpreferences = preferencemanager.getdefaultsharedpreferences(getactivity());
