解析请求数据

1：从网上xml形式请求数据。。

public static List getPull(InputStream is) {

    List<Zixun> list = null;    Zixun bean = null;    try {        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();        XmlPullParser parser = factory.newPullParser();        parser.setInput(is, "UTF_8");        int type = parser.getEventType();        while (type != XmlPullParser.END_DOCUMENT) {            String name = parser.getName();            switch (type) {            case XmlPullParser.START_DOCUMENT:                list = new ArrayList<Zixun>();                break;            case XmlPullParser.START_TAG:                if ("news".equals(name)) {                    bean = new Zixun();                } else if ("title".equals(name)) {                    bean.title = parser.nextText();                } else if ("body".equals(name)) {                    bean.body = parser.nextText();                } else if ("commentCount".equals(name)) {                    bean.commentCount = parser.nextText();                } else if ("author".equals(name)) {                    bean.author = parser.nextText();                }  else if ("pubDate".equals(name)) {                    bean.pubDate = parser.nextText();                }                break;            case XmlPullParser.END_TAG:                if ("news".equals(name)) {                    list.add(bean);                }                break;            default:                break;            }            type = parser.next();        }    } catch (Exception e) {        // TODO: handle exception    }    //一定要记住这点    return  list;}

2给它一个输入流。。。（url,HttpURLConnection ）

new Thread(){

        public void run() {            try {                URL url = new URL(path);                HttpURLConnection connection = (HttpURLConnection) url.openConnection();                connection.setRequestMethod("GET");                connection.setConnectTimeout(5000);                int code = connection.getResponseCode();                if (code == 200) {                    //服务器给我们的输入流                    InputStream is = connection.getInputStream();                    ByteArrayOutputStream baos = new ByteArrayOutputStream();                    byte[] arr = new byte[1024];                    int len = 0;                    while ((len = is.read(arr))!=-1) {                    baos.write(arr, 0, len);                    }                    String result = baos.toString();                    //Log.e("TAG", result.toString());                    Gson gson = new Gson();                    //Type type = new TypeToken<MyData>(){}.getType();                     MyData md = gson.fromJson(result, MyData.class);                    ld = (List<Datas>) md.data;                    Log.e("TAG111", ld.toString());                    hd.sendEmptyMessage(0);                }            } catch (Exception e) {                // TODO Auto-generated catch block                e.printStackTrace();            }        };    }.start();public static InputStream getinput(String path){    try {        URL url=new URL(path);        HttpURLConnection conn=(HttpURLConnection)         url.openConnection();        conn.setReadTimeout(5000);        conn.setConnectTimeout(5000);        if(conn.getResponseCode()==200){            InputStream is=conn.getInputStream();            return is;        }    } catch (Exception e) {        // TODO: handle exception    }    return null;}

3HttpUtils的请求

String path= “;

     HttpUtils hu=new HttpUtils();     hu.send(HttpMethod.GET, path, new RequestCallBack<String>() {    @Override        public void onFailure(HttpException arg0, String arg1) {        }        @Override        public void onSuccess(ResponseInfo<String> arg0) {            //请求成功             String str = arg0.result;             Gson gson=new Gson();            News  ne= gson.fromJson(str, News.class);            List<ListBean> list = ne.data.list;             Log.d("TAG", list.toString());             MyAdapter adapter=new MyAdapter(DetailActivity.this,list);                lv.setAdapter(adapter);        }    });}

3Httpclient的请求

public static String getpath(String path){
try {

                //创建httpclient                   HttpClient client=new DefaultHttpClient();        //请求方式        HttpGet get=new HttpGet(path);        HttpResponse response = client.execute(get);        //得到结果码        int statusCode = response.getStatusLine().getStatusCode();        if(statusCode==200){            return EntityUtils.toString(response.getEntity());        }    } catch (Exception e) {        // TODO: handle exception    }    return path;}
