今天完成下拉加载更多的功能：

 smartRefreshLayout.setOnRefreshListener(new OnRefreshListener() {
                 @Override
                 public void onRefresh(RefreshLayout refreshLayout) {
                     refreshXiaLa("xiala");
                     smartRefreshLayout.finishRefresh(2000);
                 }
             });
             smartRefreshLayout.setOnLoadMoreListener(new OnLoadMoreListener() {
                 @Override
                 public void onLoadMore(RefreshLayout refreshLayout) {
                     Toast.makeText(inflater.getContext(),"正在加载",Toast.LENGTH_SHORT).show();
                     refreshXiaLa("more");
                     smartRefreshLayout.finishLoadMore(2000);
                 }
             });

 if(remore.equals("xiala")){
             if(list.size()-15*page>=0){

                 recyclerView.setAdapter(recyclerAdapter2);

                 page++;
             }
             else {
                 Toast.makeText(rootView.getContext(),"已无更多刷新内容",Toast.LENGTH_SHORT).show();
             }
         }
         else if(remore.equals("more")){
             if(page-page2==1){
                page2++;

                     }
                 }
                 recyclerAdapter2=new RecyclerAdapter2(listfre);
