For example I have:

Answer 1

Use below recursive function to make your child views visible or gone. First argument is your parent view and second argument decides if you want childs of parent view visible or gone. true = visible false = gone

private void layoutElemanlarininGorunumunuDegistir(View view, boolean gorunur_mu_olsun) {
    ViewGroup view_group;
    try {
        view_group = (ViewGroup) view;
        Sabitler.konsolaYazdir(TAG, "View ViewGroup imiş!" + view.getId());
    } catch (ClassCastException e) {
        Sabitler.konsolaYazdir(TAG, "View ViewGroup değilmiş!" + view.getId());
        return;
    }

    int view_eleman_sayisi = view_group.getChildCount();
    for (int i = 0; i < view_eleman_sayisi; i++) {
        View view_group_eleman = view_group.getChildAt(i);
        if (gorunur_mu_olsun) {
            view_group_eleman.setVisibility(View.VISIBLE);
        } else {
            view_group_eleman.setVisibility(View.GONE);
        }
        layoutElemanlarininGorunumunuDegistir(view_group_eleman, gorunur_mu_olsun);
    }
}
