SwipeRefreshLayout无法更新recyclerview

Question

当我使用SwipeRefreshLayout时。 .recyclerview未更新。 在setOnRefreshListener方法中，我编写了以下命令：recyclerview命令当前未使用这些命令更新。 （我的意思是，当我从服务器编辑信息时，将不会显示该信息）

swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
    @Override
    public void onRefresh() {

        setupRecyclerView();
        swipeRefreshLayout.setRefreshing(false);
    }

});


private void setupRecyclerView() {

    recyclerView.setLayoutManager(linearLayoutManager);
    linearLayoutManager.setSmoothScrollbarEnabled(false);
    recyclerView.setAdapter(postsAdapter);
    getPosts(1);


    listemer = new EndlessRecyclerViewScrollListener(linearLayoutManager) {


        @Override
        public void onLoadMore(int page, int totalItemsCount, RecyclerView view) {

            progressBar.setVisibility(View.VISIBLE);


            getPosts(page);


            Log.e("PAGe ", "" + page);
        }

    };


    recyclerView.addOnScrollListener(listemer);


 public void getPosts(int page) {


            apiService.getPosts(page, new ApiService.OnPostsReceived() {
                @Override
                public void onReceived(List<Post> posts) {


                    openHelper.addPosts(posts);
                    postsAdapter.addpost(posts);
                    postsAdapter.notifyDataSetChanged();
                    progressDialog.hide();

                    progressBar.setVisibility(View.GONE);

                }
            });
