All the other answers are correct. But I like this alternative better because you immediately have the Preference instance that caused the change.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Preference pref = findPreference(getString(R.string.key_of_pref));        
    pref.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
        @Override
        public boolean onPreferenceChange(Preference preference, Object newValue) {
            // do whatever you want with new value

            // true to update the state of the Preference with the new value
            // in case you want to disallow the change return false
            return true;
        }
    });
}
