android开发调用webservice接口获取信息

释放双眼,带上耳机,听听看~!

 

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;

//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

holder.goodsSellNum = (EditText) convertView

holder.goodsSellNum.setTag(position);
/*holder.goodsSellNum.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {

}
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);
