You can also use this technique to override the styles of the inner preference screens :

@Override
public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen,
        Preference preference) {
    super.onPreferenceTreeClick(preferenceScreen, preference);
    if (preference != null) {
        if (preference instanceof PreferenceScreen) {
            if (((PreferenceScreen) preference).getDialog() != null) {
                ((PreferenceScreen) preference)
                        .getDialog()
                        .getWindow()
                        .getDecorView()
                        .setBackgroundDrawable(
                                this
                                .getWindow()
                                .getDecorView()
                                .getBackground()
                                .getConstantState()
                                .newDrawable()
                        );
            }
        }
    }
    return false;
}

This code applies the style of the main preference screen to the clicked preference screen.
