在Android應用中推送通知

Question

我已經使用MySQL數據庫的soap WebService開發了一個Listview應用程序。現在在我的數據庫中插入一個訂單意味着在我的android設備上顯示此消息（插入新訂單）的時間。現在我單擊通知消息意味着該時間當我的MySQL數據庫中插入每個新訂單時，該應用會運行並自動成功顯示Listview 。這里有什么方法？請幫幫我。

這是我的RetailerActivity.java代碼：

public class RetailerActivity extends Activity {
ListView list;
private static final String SOAP_ACTION = "http://xcart.com/customerData1";
private static final String METHOD_NAME = "customerData1";
private static final String NAMESPACE = "http://xcart.com";
private static final String URL = "http://192.168.1.168:8089/XcartLogin/services/RetailerWs?wsdl";
private static final String KEY_STATUS = "status";



/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.setOutputSoapObject(request);

    HttpTransportSE ht = new HttpTransportSE(URL);
    try {
        ht.call(SOAP_ACTION, envelope);
        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
        SoapPrimitive s = response;
        String str = s.toString();
        String resultArr[] = str.split("&");
        list=(ListView)findViewById(R.id.list);


        list.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1,resultArr));
        list.setOnItemClickListener(new OnItemClickListener() {

        public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) { 

                String status =  parent.getItemAtPosition(position).toString();

                String[] status1  = status.split(" ");

                 String StrStatus = status1[1].toString();

                Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
                in.putExtra(KEY_STATUS, StrStatus);

                startActivity(in);            



            }
        });     
    } 




    catch (Exception e) {
        e.printStackTrace();
    }
  }
 }

請在這里成功顯示Listview但是新訂單已插入到我的數據庫中，這意味着插入新訂單的時間是在Android設備上顯示Notification消息。現在我必須單擊通知的消息意味着它正在顯示更新Listview如何我做？？？？？？？？ 我必須在這里使用什么方法？？？？

如果您要在ListView的新數據中獲取數據，那么我認為您要做的就是

adapter.notifyDataSetChanged(); // adapter是ArrayAdapter的實例。
