android调用webservice接口获取信息

我的有一篇博客上讲了如何基于CXF搭建webservice，service层的接口会被部署到tomcat上，这一篇我就讲一下如何在安卓中调用这些接口传递参数。

1.在lib中放入ksoap2的jar包并导入

2.在xml配置文件中加入：

3.接下来就要通过代码调用借口了

StringWSDL_URI="http://localhost:8080/WebService4/getNewIdPort?wsdl";//wsdl的uri
Stringnamespace="http://services.he.TSD/";//namespace
StringmethodName="getNew";//要调用的方法名称
//创建HttpTransportSE对象
HttpTransportSEht=newHttpTransportSE(WSDL_URI);
ht.debug=true;
//使用soap1.1协议创建Envelop对象
SoapSerializationEnvelopeenvelope=newSoapSerializationEnvelope(SoapEnvelope.VER11);//实例化SoapObject对象
SoapObjectobject=newSoapObject(namespace,methodName);
//设置参数
object.addProperty("arg0","hhh");
//将SoapObject对象设置为SoapSerializationEnvelope对象的传出SOAP消息
envelope.bodyOut=object;//由于是发送请求，所以是设置bodyOut
envelope.dotNet=false;
envelope.setOutputSoapObject(object);
try{
//调用webService
ht.call(null,envelope);
System.out.println("回传的值："+envelope.getResponse());
}
catch(Exceptione){
e.printStackTrace();
Stringmsg=e.getMessage();
System.out.println(msg);
}

4.若webservice接收不到android传来的值：

（1）参数名不对

（2）.net的webservice要将envelope.dotNet=true，否则envelope.dotNet=false

5.由于是部署到tomcat上的，为了同处于一个网段，要手机和电脑连一个wifi。ipv4查找用window+R，接着cmd，最后ipconfig即可查到。

6.要关闭windows防火墙

7.当时我还遇到了一个问题，就是当传递的信息复杂时，比如传递list型的一个自定义的类，会出现问题，当时我是重写了ListAdapter类，如下所示：

packagecom.adapter;

importjava.util.ArrayList;
importjava.util.HashMap;
importjava.util.List;
importjava.util.Map;

importandroid.app.Activity;
importandroid.content.Context;
importandroid.os.Bundle;
importandroid.text.Editable;
importandroid.text.TextWatcher;
importandroid.view.LayoutInflater;
importandroid.view.View;
importandroid.view.ViewGroup;
importandroid.widget.BaseAdapter;
importandroid.widget.EditText;
importandroid.widget.ListView;
importandroid.widget.TextView;
importcom.example.administrator.stock2.R;


publicclassListAdapterextendsBaseAdapter{
HashMapitem=newHashMap();
privateLayoutInflatermInflater;
//privateList>mData;//存储的EditText值
privateArrayListmData=newArrayList();
//privateArrayListmDate=newArrayList();
publicMapeditorValue=newHashMap();//
privateTextViewspendMoney;
publicListAdapter(Contextcontext,ArrayListdata,TextViewspend){
spendMoney=spend;
mData=data;
mInflater=LayoutInflater.from(context);
init();
}

//初始化
privatevoidinit(){
editorValue.clear();
}

@Override
publicintgetCount(){
returnmData.size();
}

@Override
publicObjectgetItem(intposition){
returnnull;
}

@Override
publiclonggetItemId(intposition){
return0;
}

privateIntegerindex=-1;

@Override
publicViewgetView(intposition,ViewconvertView,ViewGroupparent){
ViewHolderholder=null;
//convertView为null的时候初始化convertView。
if(convertView==null){
holder=newViewHolder();
convertView=mInflater.inflate(R.layout.list_item,null);
holder.goodsName=(TextView)convertView
.findViewById(R.id.list_item_goodsName);
holder.goodsSellPrice=(TextView)convertView
.findViewById(R.id.list_item_goodsSellPrice);
holder.goodsUnit=(TextView)convertView
.findViewById(R.id.list_item_goodsUnit);
holder.goodsSellNum=(EditText)convertView
.findViewById(R.id.list_item_goodsSellNum);
holder.goodsSellNum.setTag(position);
/*holder.goodsSellNum.setOnTouchListener(newOnTouchListener(){
@Override
publicbooleanonTouch(Viewv,MotionEventevent){
if(event.getAction()==MotionEvent.ACTION_UP){
index=(Integer)v.getTag();
}
returnfalse;
}
});*/
classMyTextWatcherimplementsTextWatcher{
publicMyTextWatcher(ViewHolderholder){
mHolder=holder;
}

privateViewHoldermHolder;

@Override
publicvoidonTextChanged(CharSequences,intstart,
intbefore,intcount){
}

@Override
publicvoidbeforeTextChanged(CharSequences,intstart,
intcount,intafter){
}

@Override
publicvoidafterTextChanged(Editables){
if(s!=null&&!"".equals(s.toString())){
intposition=(Integer)mHolder.goodsSellNum.getTag();

/*mData.get(position).put("goodsSellNum",s.toString());//当EditText数据发生改变的时候存到data变量中*/
item=(HashMap)mData.get(position);
item.put("goodsSellNum",s.toString());
mData.set(position,item);
spendMoney.setText(String.valueOf(calculate()));//计算总价格
}
}
}
holder.goodsSellNum.addTextChangedListener(newMyTextWatcher(holder));
convertView.setTag(holder);
}else{
holder=(ViewHolder)convertView.getTag();
holder.goodsSellNum.setTag(position);
}
item=(HashMap)mData.get(position);
Objectvalue=item.get("goodsName");
//Objectvalue=mData.get(position).get("list_item_goodsName");
if(value!=null){
holder.goodsName.setText((String)value);
}
item=(HashMap)mData.get(position);
value=item.get("goodsSellPrice");
//value=mData.get(position).get("list_item_goodsSellPrice");
if(value!=null){
holder.goodsSellPrice.setText(value.toString());
}
item=(HashMap)mData.get(position);
value=item.get("goodsUnit");
//value=mData.get(position).get("list_item_goodsUnit");
if(value!=null){
holder.goodsUnit.setText(value.toString());
}
item=(HashMap)mData.get(position);
value=item.get("goodsSellNum");
//value=mData.get(position).get("list_item_goodsSellNum");
if(value!=null&&!"".equals(value)){
holder.goodsSellNum.setText(value.toString());
}
holder.goodsSellNum.clearFocus();
if(index!=-1&&index==position){
holder.goodsSellNum.requestFocus();
}
returnconvertView;
}

publicfinalclassViewHolder{
publicTextViewgoodsName;
publicTextViewgoodsSellPrice;
publicEditTextgoodsSellNum;//ListView中的输入
publicTextViewgoodsUnit;//用来定义的标志性主键,可不用关心
}
publicfloatcalculate(){
floatmoney=0;
for(inti=0;i
8.调如何用ListAdapter类
ListAdapteradapter=newListAdapter(this,list,spendMoney);
lv_goodsList.setAdapter(adapter);
