Android 访问WebService

        首先，WebService进年来的使用人数很多了，它可以是一套接口多端调用，返回的格式是JSON和XML。在项目中使用的，可以分为如下的四个步骤：
   1.下载ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar文件
   2.开始创建HttpTransportSE 对象
   3.使用Soap1.1的协议创建SoapSerializationEnvelope
   4.创建SoapObject对象
   5.设置与.NET提供的Web Service 保存更好的兼容
   6.调用Web　Service
   7.处理返回结果，解析数据。

   下面是我的源码：

    (1)WebServiceUtil.java

import org.ksoap2.SoapEnvelope;import org.ksoap2.serialization.SoapObject;import org.ksoap2.serialization.SoapSerializationEnvelope;import org.ksoap2.transport.HttpTransportSE;import java.util.concurrent.Callable;import java.util.concurrent.ExecutionException;import java.util.concurrent.FutureTask;/** * @className WebServiceUtil 的工具类 * Created by lidong on 2016/1/11. */public class WebServiceUtil {    public static SoapObject getData(String service_url, final String service_ns, final String methodName){        /**         * 创建HttpTransportSE 对象         */        final HttpTransportSE  ht = new HttpTransportSE(service_url);        ht.debug = true;        /**         * 使用Soap1.1的协议创建EEnvelope         */        final SoapSerializationEnvelope  envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);        /**         *创建SoapObject对象         */        SoapObject soapObject = new SoapObject(service_ns,methodName);        envelope.bodyOut =soapObject;        /***         * 设置与.NET提供的Web Service 保存更好的兼容         */        envelope.dotNet = true;        FutureTask<SoapObject> task = new FutureTask<SoapObject>(new Callable<SoapObject>() {            @Override            public SoapObject call() throws Exception {                //调用Web　Service                ht.call(service_ns+methodName,envelope);                if (envelope.getResponse()!=null){                    //获取服务器返回的结果                    SoapObject result = (SoapObject) envelope.bodyIn;                    return result;                }                return null;            }        });        new Thread(task).start();        try {            return  task.get();        } catch (InterruptedException e) {            e.printStackTrace();        } catch (ExecutionException e) {            e.printStackTrace();        }        return  null;    }}

   (2).布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    app:layout_behavior="@string/appbar_scrolling_view_behavior"    tools:showIn="@layout/activity_web_service_demo"    tools:context="com.chni.lidong.androidtestdemo.webService.WebServiceDemo">    <android.support.v7.widget.RecyclerView        android:layout_margin="10dp"        android:layout_height="match_parent"        android:layout_width="match_parent"        android:id="@id/recyclerView"/></RelativeLayout>

3.WebServiceDemo

 

import android.os.Bundle;import android.support.design.widget.FloatingActionButton;import android.support.design.widget.Snackbar;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.support.v7.widget.Toolbar;import android.util.Log;import android.view.View;import com.chni.lidong.androidtestdemo.R;import com.chni.lidong.androidtestdemo.webService.adapter.MyAdapter;import com.chni.lidong.androidtestdemo.webService.model.CarType;import com.google.gson.Gson;import org.ksoap2.serialization.SoapObject;/** * 访问WebService的demo */public class WebServiceDemo extends AppCompatActivity {    //WSDL文档中的命名空间    private static final String nameSpace = "http://www.ichehang.com/";    //WSDL文档中的URL    private static final String endPoint = "http://app.ichehang.com/AppService.asmx";    //调用的方法    private static final String methodName = "GetBrandNew";    private RecyclerView recyclerView;    private CarType carType;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_web_service_demo);        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);        setSupportActionBar(toolbar);        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);        fab.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)                        .setAction("Action", null).show();            }        });        SoapObject data = WebServiceUtil.getData(endPoint, nameSpace, methodName);        Log.d("WebServiceDemo",data.getPropertyCount()+"      "+data.getProperty(0) + "");        parseData( data);        recyclerView = (RecyclerView) findViewById(R.id.recyclerView);        // 创建一个线性布局管理器        LinearLayoutManager layoutManager = new LinearLayoutManager(this);        // 设置布局管理器        recyclerView.setLayoutManager(layoutManager);        recyclerView.setAdapter(new MyAdapter(carType));    }    private void parseData(SoapObject data) {         carType = new Gson().fromJson(data.getProperty(0).toString(), CarType.class);    }}

  4.MyAdapter.java 

import android.support.v7.widget.RecyclerView;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;import com.chni.lidong.androidtestdemo.R;import com.chni.lidong.androidtestdemo.webService.model.CarType;/** * Created by Administrator on 2016/1/11. */public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>   {    private  CarType mDataset;    public MyAdapter(CarType mDataset) {        this.mDataset = mDataset;    }    @Override    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = View.inflate(parent.getContext(), R.layout.my_adapter_detail, null);        // 创建一个ViewHolder        ViewHolder holder = new ViewHolder(view);        return holder;    }    @Override    public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) {        holder.mTextView.setText(mDataset.getTable().get(position).getName());        holder.mTextViewName.setText(mDataset.getTable().get(position).getImgname());    }    @Override    public int getItemCount() {        return mDataset.getTable().size();    }    public static class ViewHolder extends RecyclerView.ViewHolder    {        public TextView mTextView;        public TextView mTextViewName;        public ViewHolder(View itemView)        {            super(itemView);            mTextView = (TextView) itemView.findViewById(R.id.textView6);            mTextViewName = (TextView) itemView.findViewById(R.id.textView7);        }    }}

（6）CarType.java

import java.util.List;/** * Created by lidong on 2016/1/11. */public class CarType {    /**     * recordcount : 22     * table : [{"no":"1","id":"9","name":"奔驰","imgname":"ppxl"},{"no":"2","id":"11","name":"宝马","imgname":"baoma"},{"no":"3","id":"12","name":"保时捷","imgname":"baoshijie"},{"no":"4","id":"13","name":"奥迪","imgname":"aodi"},{"no":"5","id":"14","name":"路虎","imgname":"luhu"},{"no":"6","id":"15","name":"尼桑","imgname":"nisang"},{"no":"7","id":"16","name":"福特","imgname":"fute"},{"no":"8","id":"17","name":"丰田","imgname":"fengtian"},{"no":"9","id":"39","name":"玛莎拉蒂","imgname":"msld"},{"no":"10","id":"40","name":"克尔维特","imgname":"kewt"},{"no":"11","id":"51","name":"JEEP","imgname":"jeep"},{"no":"12","id":"53","name":"林肯","imgname":"linken"},{"no":"13","id":"73","name":"雷克萨斯","imgname":"lkss"},{"no":"14","id":"76","name":"道奇","imgname":"daoqi"},{"no":"15","id":"82","name":"凯迪拉克","imgname":"kaidilake"},{"no":"16","id":"93","name":"沃尔沃","imgname":"16kuanwoerwo"},{"no":"17","id":"95","name":"GMC","imgname":"GMC"},{"no":"18","id":"97","name":"宾利","imgname":"binli"},{"no":"19","id":"101","name":"法拉利","imgname":"falali"},{"no":"20","id":"113","name":"斯达泰克","imgname":"sidataike"},{"no":"21","id":"114","name":"大众","imgname":"dayin"},{"no":"22","id":"120","name":"乔治巴顿","imgname":"qiaozhibadu"}]     */    private String recordcount;    /**     * no : 1     * id : 9     * name : 奔驰     * imgname : ppxl     */    private List<TableEntity> table;    public void setRecordcount(String recordcount) {        this.recordcount = recordcount;    }    public void setTable(List<TableEntity> table) {        this.table = table;    }    public String getRecordcount() {        return recordcount;    }    public List<TableEntity> getTable() {        return table;    }    public static class TableEntity {        private String no;        private String id;        private String name;        private String imgname;        public void setNo(String no) {            this.no = no;        }        public void setId(String id) {            this.id = id;        }        public void setName(String name) {            this.name = name;        }        public void setImgname(String imgname) {            this.imgname = imgname;        }        public String getNo() {            return no;        }        public String getId() {            return id;        }        public String getName() {            return name;        }        public String getImgname() {            return imgname;        }    }}
