JSON，XML连接到Android的web api？

我是Android和Java世界的新手，我想知道如何从web api获取数据http://www.imdbapi.com/进入android。 我应该使用JSON还是XML？ 步骤是什么？ 首先，我想知道如何下载数据，然后如何将其解析为变量。 任何示例代码？

Answer 1

HttpClient httpclient = new DefaultHttpClient(); // Prepare a request object HttpGet httpget = new HttpGet(url); // Execute the request HttpResponse response; JSONArray arr = new JSONArray(); try { response = httpclient.execute(httpget); HttpEntity entity = response.getEntity(); if (entity != null && response.getStatusLine().getStatusCode() == 200) { // A Simple JSON Response Read InputStream instream = entity.getContent(); String result = convertStreamToString(instream); arr=new JSONArray(result); instream.close(); } } catch (ClientProtocolException e) { // TODO Auto-generated catch block Log.e(TAG,e.toString()); } catch (IOException e) { // TODO Auto-generated catch block Log.e(TAG,e.toString()); } catch (JSONException e) { // TODO Auto-generated catch block Log.e(TAG,e.toString()); } return arr; public static String convertStreamToString(InputStream is) { BufferedReader reader = new BufferedReader(new InputStreamReader(is)); StringBuilder sb = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } } catch (IOException e) { Log.e(TAG + "ERROR",e.toString()); } finally { try { is.close(); } catch (IOException e) { e.printStackTrace(); Log.e(TAG + "ERRO",e.toString()); } } return sb.toString(); } 

至于解析，请转到： http ： //developer.android.com/reference/org/json/package-summary.html

顺便说一句，这很容易在谷歌上找到:)
