  wemall-mobile是基于WeMall的android app商城，只需要在原商城目錄下上傳接口文件即可完成服務(wù)端的配置，客戶端可定制修改。本文分享Android 獲取XML網(wǎng)絡(luò)數(shù)據(jù)并綁定到ListView，對數(shù)據(jù)進(jìn)行獲取并顯示代碼信息，供技術(shù)員參考學(xué)習(xí)。

1、添加ListView中每一項(xiàng)的item

   2、添加實(shí)體類NewsObj

public class NewsObj implements Serializable {
　　private String name;
　　private int id;
}// 省去屬性get和set方法

   3、添加一個(gè)類用于處理請求消息

public class NewsService {
    // 解析XML數(shù)據(jù)
    private static List parseXML(InputStream ins) throws Exception {
        List list = new ArrayList();
        NewsObj obj = null;
        XmlPullParser parser = Xml.newPullParser();
        parser.setInput(ins, "UTF-8");
        int event = parser.getEventType();
        while (event != XmlPullParser.END_DOCUMENT) {
            switch (event) {
            case XmlPullParser.START_TAG:
                if ("news".equals(parser.getName())) {
                    int id = new Integer(parser.getAttributeValue(0));
                    obj = new NewsObj();
                    obj.setId(id);
                } else if ("name".equals(parser.getName())) {
                    obj.setName(parser.nextText());
                }
                break;
            case XmlPullParser.END_TAG:
                if ("news".equals(parser.getName())) {
                    list.add(obj);
                    obj = null;
                }
                break;
            }
            event = parser.next();
        }
        return list;
    }
 
    // 獲取最新的資訊
    public static List getLastnews(String Urlpath) throws Exception {
        URL url = new URL(Urlpath);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setConnectTimeout(5000);
        conn.setRequestMethod("GET");
        Log.i("CONN", conn.toString());
        if (conn.getResponseCode() == 200) {
            InputStream ins = conn.getInputStream();
            return parseXML(ins);
        }
        return null;
    }
}

   4、修改MainActivity

public class MainActivity extends Activity {
    private Handler handler;
    private SimpleAdapter adapter;
    private ListView lv;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        lv = (ListView) findViewById(R.id.lv);
        handler = new Handler();
        new Thread(runa).start();
    }
    
    private Runnable setadapter = new Runnable() {
        @Override
        public void run() {
            lv.setAdapter(adapter);
        }
    };
 
    private void SetView() {
        try {
            List videos = NewsService.getLastnews("http://10.0.2.2:4484/WebSite1/XMLFile.xml");
            List> data = new ArrayList>();
            for (NewsObj news : videos) {
                HashMap item = new HashMap();
                item.put("id", news.getId());
                item.put("name", news.getName());
                data.add(item);
            }
            adapter = new SimpleAdapter(getApplicationContext(), data,
                    R.layout.item, new String[] { "id", "name" }, new int[] { R.id.record, R.id.name });
            handler.post(setadapter); // 添加一個(gè)任務(wù)到主線程的handler！！！
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
 
    private Runnable runa = new Runnable() {
        @Override
        public void run() {
            Looper.prepare();
            SetView();
        }
    };
}

   5、添加一個(gè)web測試項(xiàng)
   上一步中網(wǎng)站請求地址返回的數(shù)據(jù)如下

    
    
    　　
    　　　　hello world
    　　
    　　
    　　　　Livingstone

   6、添加網(wǎng)絡(luò)訪問權(quán)限，運(yùn)行程序
