JSON，XML连接Web API为Android？

问题描述

我是pretty新的Andr​​oid和Java的世界，我想知道我是如何从Web API这里的进入机器人。
我应该使用JSON或XML？
哪些步骤？首先，我想知道如何下载数据，然后如何将它解析为变量。
任何样品code？

解决方案

 的HttpClient HttpClient的=新DefaultHttpClient（）;
    // prepare请求对象
    HTTPGET HTTPGET =新HTTPGET（URL）;
    //执行请求
    HTT presponse响应;    JSONArray ARR =新JSONArray（）;
    尝试{
       响应= httpclient.execute（HTTPGET）;       HttpEntity实体= response.getEntity（）;       如果（实体= NULL＆放大器;！＆安培; response.getStatusLine（）的getStatus code（）== 200）{
                //一个简单的JSON响应读取
                InputStream的河道= entity.getContent（）;
                字符串结果= convertStreamToString（插播广告）;
                ARR =新JSONArray（结果）;
                instream.close（）;            }
        }赶上（ClientProtocolException E）{
            // TODO自动生成catch块
            Log.e（TAG，e.toString（））;
        }赶上（IOException异常五）{
            // TODO自动生成catch块
            Log.e（TAG，e.toString（））;
        }赶上（JSONException E）{
            // TODO自动生成catch块
            Log.e（TAG，e.toString（））;
        }        返回ARR;
公共静态字符串convertStreamToString（InputStream为）{
    读者的BufferedReader =新的BufferedReader（新的InputStreamReader（是））;
    StringBuilder的SB =新的StringBuilder（）;    串线= NULL;
    尝试{
        而（（行= reader.readLine（））！= NULL）{
            sb.append（行+\\ n）;
        }
    }赶上（IOException异常五）{
        Log.e（TAG +ERRORe.toString（））;    } {最后
        尝试{
            is.close（）;
        }赶上（IOException异常五）{
            e.printStackTrace（）;
            Log.e（TAG +ERRO，e.toString（））;
        }
    }
    返回sb.toString（）;
}
 

至于解析，在这里你去：

顺便说一句，这是很容易的所有谷歌上找到：）

I am pretty new to the world of Android and Java and I am wondering how I get data from the web api here http://www.imdbapi.com/ Into android.Should I use JSON or XML?What are the steps? Firstly I want to know how to download the data and then how to parse it to variables.Any sample code?

解决方案

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();
}

As for parsing, here you go: http://developer.android.com/reference/org/json/package-summary.html

btw, this was all easily found on google : )
