android調用webservice介面擷取資訊

標籤：參數   int   turn   .net   imp   widget   匯入   nts   hex   

我的有一篇部落格上講了如何基於CXF搭建webservice，service層的介面會被部署到tomcat上，這一篇我就講一下如何在安卓中調用這些介面傳遞參數。

1.在lib中放入ksoap2的jar包並匯入

 

2.在xml 設定檔中加入：

<!-- 訪問網路的許可權 -->      <uses-permission android:name="android.permission.INTERNET" /> 

 

3.接下來就要通過代碼調用借口了

String WSDL_URI = "http://localhost:8080/WebService4/getNewIdPort?wsdl";//wsdl 的uriString namespace = "http://services.he.TSD/";//namespaceString methodName = "getNew";//要調用的方法名稱// 建立HttpTransportSE對象HttpTransportSE ht = new HttpTransportSE(WSDL_URI);ht.debug = true;// 使用soap1.1協議建立Envelop對象SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);// 執行個體化SoapObject對象SoapObject object = new SoapObject(namespace, methodName);// 設定參數object.addProperty("arg0", "hhh");// 將SoapObject對象設定為SoapSerializationEnvelope對象的傳出SOAP訊息envelope.bodyOut = object;//由於是發送請求，所以是設定bodyOutenvelope.dotNet =false;envelope.setOutputSoapObject(object);try{  // 調用webService  ht.call(null, envelope);  System.out.println("回傳的值 ："+envelope.getResponse());}catch (Exception e) {  e.printStackTrace();  String msg=e.getMessage();  System.out.println(msg);}

 

4.若webservice接收不到android傳來的值：

  （1）參數名不對

  （2）.net的webservice要將envelope.dotNet =true，否則envelope.dotNet =false

 

5.由於是部署到tomcat上的，為了同處於一個網段，要手機和電腦連一個wifi。 ipv4尋找用window+R，接著cmd，最後ipconfig 即可查到。

 

6.要關閉windows防火牆

 

7.當時我還遇到了一個問題，就是當傳遞的資訊複雜時，比如傳遞list型的一個自訂的類，會出現問題，當時我是重寫了ListAdapter類，如下所示：

               }                private ViewHolder mHolder;                @Override                public void onTextChanged(CharSequence s, int start,                                          int before, int count) {                }                @Override                public void beforeTextChanged(CharSequence s, int start,                                              int count, int after) {                }                @Override                public void afterTextChanged(Editable s) {                    if (s != null && !"".equals(s.toString())) {                        int position = (Integer) mHolder.goodsSellNum.getTag();

           convertView.setTag(holder);        } else {            holder = (ViewHolder) convertView.getTag();            holder.goodsSellNum.setTag(position);        }        item=(HashMap)mData.get(position);

8.調如何用ListAdapter類

ListAdapter adapter = new ListAdapter(this, list,spendMoney); 
lv_goodsList.setAdapter(adapter);
