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,下面就让爱站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uri String namespace = "http://services.he.TSD/";//namespace String 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 (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);
