android开发的时候有很多的接口,我们在调用WebService服务接口时,需要将cookies作为附加项传递,别着急,下面就让武林技术频道小编带大家学习android调用webservice接口获取信息吧!

1.在lib中放入ksoap2的jar包并导入

2.在xml 配置文件中加入:

<!-- 访问网络的权限 -->   <uses-permission android:name="android.permission.INTERNET" /> 

3.接下来就要通过代码调用借口了

String WSDL_URI = "http://localhost:8080/WebService4/getNewIdPort?wsdl";//wsdl 的uriString namespace = "http://services.he.TSD/";//namespaceString methodName = "getNew";//要调用的方法名称// 创建HttpTransportSE对象HttpTransportSE ht = new HttpTransportSE(WSDL_URI);ht.debug = true;// 使用soap1.1协议创建Envelop对象SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);// 实例化SoapObject对象SoapObject object = new SoapObject(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bodyOutenvelope.dotNet =false;envelope.setOutputSoapObject(object);try{ // 调用webService ht.call(null, envelope); System.out.println("回传的值 :"+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:

 

package com.adapter;/** * Created by hexiaolu on 2017/4/13. */import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import android.app.Activity;import android.content.Context;import android.os.Bundle;import android.text.Editable;import android.text.TextWatcher;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.EditText;import android.widget.ListView;import android.widget.TextView;import com.example.administrator.stock2.R;public class ListAdapter extends BaseAdapter {  HashMap item = new HashMap();  private LayoutInflater mInflater;  //private List<Map<String, Object>> mData;// 存储的EditText值  private ArrayList mData=new ArrayList();  //private ArrayList mDate = new ArrayList();  public Map<String, String> editorValue = new HashMap<String, String>();//  private TextView spendMoney;  public ListAdapter(Context context, ArrayList data,TextView spend) {    spendMoney=spend;    mData = data;    mInflater = LayoutInflater.from(context);    init();  }  // 初始化  private void init() {    editorValue.clear();  }  @Override  public int getCount() {    return mData.size();  }  @Override  public Object getItem(int position) {    return null;  }  @Override  public long getItemId(int position) {    return 0;  }  private Integer index = -1;  @Override  public View getView(int position, View convertView, ViewGroup parent) {    ViewHolder holder = null;    // convertView为null的时候初始化convertView。    if (convertView == null) {      holder = new ViewHolder();      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(new OnTouchListener() {        @Override        public boolean onTouch(View v, MotionEvent event) {          if (event.getAction() == MotionEvent.ACTION_UP) {            index = (Integer) v.getTag();          }          return false;        }      });*/      class MyTextWatcher implements TextWatcher {        public MyTextWatcher(ViewHolder holder) {          mHolder = holder;        }        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();            /*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(new MyTextWatcher(holder));      convertView.setTag(holder);    } else {      holder = (ViewHolder) convertView.getTag();      holder.goodsSellNum.setTag(position);    }    item=(HashMap)mData.get(position);    Object value=item.get("goodsName");    //Object value = 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();    }    return convertView;  }  public final class ViewHolder {    public TextView goodsName;    public TextView goodsSellPrice;    public EditText goodsSellNum;// ListView中的输入    public TextView goodsUnit;// 用来定义的标志性主键,可不用关心  }  public float calculate() {    float money = 0;    for (int i = 0; i < mData.size(); i++) {      HashMap item = new HashMap();      item = (HashMap) mData.get(i);      float num = Float.parseFloat(item.get("goodsSellNum").toString());      float price = Float.parseFloat(item.get("goodsSellPrice").toString());      money = money + num * price;    }    return money;  }}

8.调如何用ListAdapter类

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