 在mainActivity中

        List fragments = new ArrayList<>();
        url = new ArrayList<>();
        url.add("https://api.dyhoa.com/dapi/v4/bbs/articleList?sign=d88edfe6fe2e3cf8f0b10dc7ded91f0e×tamp=1530932284&os=1501&phone=&nextPage=1&terminal=1601&pageSize=20&nonceStr=554644c0cc70e64757bfdfe8512f90c6&mid=&type=2&signature=7798327cfd70931d564eda4cd63e2501ec595cf5&version=3.6.8.9");

        for (int i = 0; i < url.size(); i++) {
            fragments.add(Fragment1.newInstance(url.get(i), ""));
        }

复用的fragment中

   IPresenter iPresenter = new IPresenter(this);
        iPresenter.getData(mParam1);//直接用参数1  fragme必须是完整版的
