Android调用Java WebSevice篇之二

1.创建Activity。

package com.web;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.StrictMode;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class WebServiceTestActivity extends Activity implements OnClickListener {

    private EditText et_param01;
    private EditText et_param02;
    private EditText et_param03;
    private Button btn_submit;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        et_param01 = (EditText) findViewById(R.id.et_param01);
        et_param02 = (EditText) findViewById(R.id.et_param02);
        et_param03 = (EditText) findViewById(R.id.et_param03);
        btn_submit = (Button) findViewById(R.id.btn_submit);
        btn_submit.setOnClickListener(this);

        /**
         * 防止android.os.NetworkOnMainThreadException异常
         * 参考http://dev.wo.com.cn/docportal/doc_queryMdocDetail.action?mdoc.docindex=6695
         */
        StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                .detectDiskReads().detectDiskWrites().detectNetwork()
                .penaltyLog().build());
        StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                .detectLeakedSqlLiteObjects().detectLeakedClosableObjects()
                .penaltyLog().penaltyDeath().build());

    }

    public String callService(String param1, String param2) {
        try {
            // 命名空间
            String nameSpace = "http://10.8.60.63:8088/webservice/services/webCallService/";
            // 调用的方法名称
            String methodName = "callService";
            // SOAP Action
            String soapAction = nameSpace + methodName;
            SoapObject request = new SoapObject(nameSpace, methodName);
            request.addProperty("param1", param1);
            request.addProperty("param2", param2);
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.bodyOut = request;
            envelope.setOutputSoapObject(request);
            envelope.encodingStyle="UTF-8";
            HttpTransportSE transport = new HttpTransportSE(
                    "http://10.8.60.63:8088/webservice/services/webCallService");// wsdl文档

            try {
                // 调用WebService
                transport.call(soapAction, envelope);
                // transport.call(null, envelope);
            } catch (Exception e) {
                e.printStackTrace();
            }
            Object obj =  envelope.getResponse();

            return obj.toString();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        }

    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.btn_submit:
            new Thread() {
                @Override
                public void run() {
                    // 你要执行的方法
                    // 执行完毕后给handler发送一个空消息
                    handler.sendEmptyMessage(0);
                }
            }.start();
            break;
        }
    }

    // 定义Handler对象
    private Handler handler = new Handler() {
        @Override
        // 当有消息发送出来的时候就执行Handler的这个方法
        public void handleMessage(Message msg) {
            // 处理UI
            String str = (String) callService(
                    et_param01.getText().toString(), et_param02.getText()
                            .toString());
            if (str == null || "".equals(str)) {
                str = "返回值为空";
            }
            et_param03.setText(str);

        }
    };

}

2.配置清单文件。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.web"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="15" />
    <!-- 访问网络的权限 -->
    <uses-permission android:name="android.permission.INTERNET" /> 

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".WebServiceTestActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

3.测试效果。
