Question

Currently I have the codes like this:

back.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        //DO STUFF
        return true;
    }
});
music.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        //DO OTHER STUFF
        return false;
    }
});
sound.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
    public boolean onPreferenceChange(Preference preference, Object newValue) {
        //DO MORE STUFF
        return true;
    }
});

Is it possible that there’s a way to optimize this piece of code like this somehow? Thanks in advance.

Thanks to njzk2, I was given a hint on how to consolidate all the implemented methods into one big object. Just make a nested class and use that to implement the interfaces.
