two fragments in the same Activity

Question

My fragment extends BaseFragment which has CMYJsonHttpResponseHandler in it. and if the handler returns error num -622. the basefragment will launch a dialog. and my two fragments in the same Activity. so the dialog will create twice. but i want to crate once in the activity. activity code is like this:

CMYGoodsListFragment commodityFragment = new CMYGoodsListFragment(this);
        Bundle commodityBundle = new Bundle();
        commodityBundle.putString(KEY_INTENT_ID, "1");
        commodityFragment.setArguments(commodityBundle);
        fragments.add(commodityFragment);

        CMYGoodsListFragment serviceFragment = new CMYGoodsListFragment(this);
        Bundle serviceBundle = new Bundle();
        serviceBundle.putString(KEY_INTENT_ID, "2");
        serviceFragment.setArguments(serviceBundle);
        fragments.add(serviceFragment);

    {
            if(dialog!=null && dialog.isShowing())

             /** Here create dialog */
    }
