E / RecyclerView：未连接适配器；跳过布局而不在recyclerview中显示数据

你需要

return drawer;

inflater.inflate(R.layout.fragment_one,container, false);

onCreateView()

编辑

@Override        public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { View drawer = inflater.inflate(R.layout.fragment_one, container, false); feedsList = new ArrayList<FeedItem>(); mRecyclerView = (RecyclerView) drawer.findViewById(R.id.recycler_view); mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity())); progressBar = (ProgressBar) drawer.findViewById(R.id.progress_bar); String url = "http://krishscs.esy.es/RecycleViewExample/RecycleViewExample.php"; mSearchView = (SearchView) drawer.findViewById(R.id.search_view); setupSearchView(); new DownloadTask().execute(url); adapter = new MyRecyclerViewAdapter(getActivity(),feedsList); Toast.makeText(getActivity(), "HELLO", Toast.LENGTH_SHORT).show(); mRecyclerView.setAdapter(adapter); // Inflate the layout for this fragment return drawer;        }

试试这个

private void parseResult(String result) { try {     feedsList = new ArrayList<FeedItem>();     JSonObject response = new JSonObject(result);     JSonArray posts = response.optJSonArray("result");     for (int i = 0; i < posts.length(); i++) {         JSonObject post = posts.optJSonObject(i);         FeedItem item = new FeedItem();         item.setTitle(post.optString("name"));         item.setThumbnail(post.optString("image"));         feedsList.add(item);     }     adapter = new MyRecyclerViewAdapter(getActivity(),feedsList);     mRecyclerView.setAdapter(adapter);     Log.d("POSTDATA",feedsList.toString() ); } catch (JSonException e) {     e.printStackTrace(); }        }
