Override onSharedPreferenceChanged in your PreferenceActivity class:

public class MyPreferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
    ...
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
        if (key.equals("MyCheckboxPreferenceKey")) {
            //Show your AlertDialog here!
        }
    }
