OnPreferenceChangeListener for each setting

Question

I know I can do something like this:

Preference pref = findPreference(getString(R.string.pref_vibrate_on_key));
pref.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {

        @Override
        public boolean onPreferenceChange(Preference preference,
                Object newValue) {
            LogUtil.d("Working!");
            return true;
        }

});

But I would like to add a listener to every preference. I tried:

SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
sp.registerOnSharedPreferenceChangeListener(new OnSharedPreferenceChangeListener() {

        @Override
        public void onSharedPreferenceChanged(
                SharedPreferences sharedPreferences, String key) {
            LogUtil.d("working!");

        }

});

but that will not work. Is it possible? If so, what am I doing wrong?

Answer 1

Assuming you call the same listener each time, this might be a simpler solution:

Preference.OnPreferenceChangeListener changeListener = new Preference.OnPreferenceChangeListener() {
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        // Code goes here            
        return true;
    }
};

EditTextPreference pref = (EditTextPreference)findPreference(getString(R.string.pref1));
pref1.setOnPreferenceChangeListener(changeListener);

EditTextPreference pref2 = (EditTextPreference)findPreference(getString(R.string.pref2));
pref2.setOnPreferenceChangeListener(changeListener);
