Answer 1

What is the problem?

Resolve the preference and set a listener that does the toast? Something like this for example

ListPreference listPreference = findPreference(key);
    listPreference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
        @Override
        public boolean onPreferenceChange(Preference preference, Object newValue) {
            Toast.makeText(SettingsActivity.this, "second", Toast.LENGTH_LONG).show();
            return true;
        }
    });

@Blotto Sometimes the man pages can be your friend, take a read of this link and then look at your preferences.xml file, the light bulb moment will come shortly thereafter. – Aubry
