获取片段的视图,并禁用整个视图

FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = fragmentManager.findFragmentById(R.id.fragment_container);
View fragmentView = fragment.getView();

fragmentView.setEnabled(false);

private void setViewAndChildrenEnabled(View view, boolean enabled) {
    view.setEnabled(enabled);
    if (view instanceof ViewGroup) {
        ViewGroup viewGroup = (ViewGroup) view;
        for (int i = 0; i< viewGroup.getChildCount(); i++) {
            setViewAndChildrenEnabled(viewGroup.getChildAt(i), enabled);
        }
    }
}

setViewAndChildrenEnabled(fragmentView, false);
