第二阶段冲刺九

今天主要完成的任务：安卓端接收JSON数据，并构造适配器

遇到的困难：JSON数据格式转化问题

解决办法：引入阿里巴巴的json工具包即可

源程序代码：

LinearLayoutManager linearLayoutManager=new LinearLayoutManager(mContext);
        recyclerView.setLayoutManager(linearLayoutManager);
        String url = "http://39.101.190.190:8080/CloudNoteServlet/NoteServlet";
        OkHttpUtils
                .get( )
                .url(url)
                .addParams("method", "getpublicNotes")
                .build( )
                .execute(new StringCallback( )
                {
                    @Override
                    public void onError(Call call, Exception e, int id)
                    {
                        Toast.makeText(mContext,"网络异常", Toast.LENGTH_SHORT).show( );
                    }

                    @Override
                    public void onResponse(String response, int id)
                    {
                        JSONArray array = JSONArray.parseArray(response);
                        for (int i = 0; i < array.size( ); i++)
                        {
                            JSONObject json = array.getJSONObject(i);
                            Note_pojo notePojo = new Note_pojo();
                            notePojo.setNote_id(json.getInteger("note_id"));
                            notePojo.setUser_icon(json.getString("user_icon"));
                            notePojo.setUser_name(json.getString("username"));
                            notePojo.setTitle(json.getString("title"));
                            notePojo.setCourse(json.getString("course"));
                            notePojo.setDate(json.getString("date"));
                            notePojoList.add(notePojo);
                        }
                        if(flag)
                        {
                            publicNoteAdapter.refreshList();
                            swipeRefreshLayout.setRefreshing(false);//当刷新结束时隐藏刷新条
                        }
                        else
                        {
                            initView();
                        }

                    }

                });
