篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了解析聚合数据中的菜谱大全相关的知识，希望对你有一定的参考价值。
1、首先你需要注册聚合数据，获取相应的KEY
如图：
2、得到相应的key后，我们就可以通过代码来获取数据了，具体代码如下:
/** * 获取菜谱数据 */ public class CaiPumMenueActivity extends Activity { //配置您申请的KEY public static final String APPKEY = "82ca66***********49a93e5"; String apiAddress = "http://apis.juhe.cn/cook/query?key=" + APPKEY + "&menu=午餐&rn=10&pn=3"; /** * 请求菜谱数据 * @param url:请求 用AsyncTask异步请求 */ public void readNet(String url) //请求菜谱数据 { new AsyncTask<String, String, String>() { StringBuilder sb; @Override protected String doInBackground(String... params) { try { URL url = new URL(params[0]); URLConnection connection = url.openConnection(); //建立连接 InputStream inputStream = connection.getInputStream(); InputStreamReader inputStreamReader = new InputStreamReader(inputStream); BufferedReader br = new BufferedReader(inputStreamReader); String line; sb = new StringBuilder(); while ((line = br.readLine()) != null) { sb.append(line); } br.close(); inputStream.close(); return sb.toString(); } catch (MalformedURLException e) { Toast.makeText(CaiPumMenueActivity.this, "获取数据异常", Toast.LENGTH_LONG).show(); e.printStackTrace(); } catch (IOException e) { Toast.makeText(CaiPumMenueActivity.this, "数据流异常", Toast.LENGTH_LONG).show(); e.printStackTrace(); } } @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected void onPostExecute(String s) { try { if(s.equals(null)) { //readjson("zaocan.json"); //从本地读取json数据 Toast.makeText(CaiPumMenueActivity.this,"获取资源失败",Toast.LENGTH_SHORT).show(); }} /** * 开始解析json数据 * @param sb * @throws JSONException */ public void startJson(String sb) throws JSONException { JSONObject root = new JSONObject(sb); if ("Success".equals(root.getString("reason"))) { List<Map<String, Object>> list = null; list = new ArrayList<Map<String, Object>>(); Map<String, Object> map = null; result = root.getString("result"); JSONObject root1 = new JSONObject(result); //int totalNum = root1.getInt("totalNum"); JSONArray jsonArray = root1.getJSONArray("data");//处理json数组 for (int i = 0; i < jsonArray.length(); i++) { JSONObject tree = jsonArray.getJSONObject(i); id = tree.getInt("id"); title = tree.getString("title"); tags = tree.getString("tags"); imtro = tree.getString("imtro"); ingredients = tree.getString("ingredients"); burden = tree.getString("burden"); JSONArray album = tree.optJSONArray("albums"); albums = album.getString(0); //图片地址 map = new HashMap<String, Object>(); map.put("id", id); map.put("title", title); //菜名 map.put("imtro", imtro); //简介 map.put("albums", albums);//菜谱地址 JSONArray steps = tree.getJSONArray("steps");//菜谱步骤 for (int j = 0; j < steps.length(); j++) { JSONObject ste = steps.getJSONObject(j); img = ste.getString("img"); step = ste.getString("step"); map.put("img", img); map.put("step", step); //list.add(map); } list.add(map); } Toast.makeText(CaiPumMenueActivity.this, "获取菜谱失败:" + root.getString("reason")+"}}+"+list.size(), Toast.LENGTH_LONG).show(); /** * 设置适配器并将 list集合传过去 */ listView = (ListView) findViewById(R.id.caipu_lv); listView.setAdapter(new JsonAdapter(CaiPumMenueActivity.this, list,listView)); } else { Toast.makeText(CaiPumMenueActivity.this, "获取菜谱失败" + root.getString("reason"), Toast.LENGTH_LONG).show(); } } }.execute(url); } }
