PreferenceActivity - EditTextPreference - on value changed

Question

I have an EditTextPreference (key "userfirstname"). I want to call method when it has been changed. I read documentation of PreferenceActivity and EditTextPreference, but I didn't find relevant solution.

Is there any way to do that ?

Answer 1

Preference userNamePref = findPreference("userfirstname");
userNamePref.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {

        @Override
        public boolean onPreferenceChange(Preference preference,
                Object newValue) {
            //do something
            return true;
        }

});
