如上异常，活动已经被销毁。

主要是Transaction的commit方法时，出现的错误，

// 开启事物
        FragmentTransaction transaction = fragmentManager.beginTransaction();
        // if (headviewPager == null) {
        // headviewPager = new GoodsDetailHeadViewPagerFragment();
        // headviewPager.setGoodsDetail(goodsDetail);
        // transaction.add(R.id.fragment_head_detail_page, headviewPager);
        // }

        if (goodsAttr == null) {
            goodsAttr = new GoodsDetailGoodsAttrFragment();
            goodsAttr.setGoods(goodsDetail.getGoods());
            transaction.add(R.id.fragment_goods_attr_area, goodsAttr);
        }

        // 事物提交
        if (transaction != null) {
//            transaction.commitAllowingStateLoss();
            transaction.commit();
        }

就这么写，之后测了几次没有出现这个错误了。但是我觉得还是没有解决
