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

            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

        // 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);
    }
}

    }

    @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)

        }

    }
