大叔的第四天 @HTTP请求，JSON，LISTVIEW

做了一个页面，同时用到了这三种不会的知识，写到这里。Map还要理解一下。

public class SingleActivity extends Activity{
    private ListView listView;
    private ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
    SimpleAdapter adapter = null ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.maintenance_single);
        listView = (ListView)findViewById(R.id.maintenance_single_list);
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        //这里是网络请求的附加信息
        BasicNameValuePair pair1 = new BasicNameValuePair("UserAgent", Constands.UserAgent);//附加信息
        params.add(pair1);
        BasicNameValuePair pair2 = new BasicNameValuePair("Token", "34430000003165727730");//附加信息
        params.add(pair2);
        
        

        new HttpConnection().post("get_item", params,new HttpConnection.CallbackListener() {

            @Override
            public void callBack(String result) {
                Log.v("post了",result);
                if(result!="fail"){
                    try {
                        
                        
                        //JASON解析
                        JSONObject object = new JSONObject(result);
                        JSONArray content = object.getJSONArray("Content");
                        int cc = content.length();
                        
                        for(int i=0;i<cc;i++){
                            JSONObject objMap = content.getJSONObject(i);
                            HashMap<String,String> map = new HashMap<String,String>();
                            map.put("code",objMap.getString("code"));
                            map.put("name",objMap.getString("name"));
                            list.add(map);
                            Log.v("Content01",map.get("code"));
                            Log.v("Content01",map.get("name"));
                            
                        }
                        Log.v("TEST LIST",list.get(0).get("name"));
                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    adapter = new SimpleAdapter(
                            SingleActivity.this,
                            list,
                            R.layout.sositemrow,
                            new String[]{"name"},
                            new int[]{R.id.itemtitle});
                     
                    listView.setAdapter(SingleActivity.this.adapter);    
                    
                }else{    
                }    
            }    
        });    
        
    }
