android 調用webservice
android端與服務器交互 一般情況下,我們可以使用SOCKET,HTTP(GET,POST)等,我們也可以使用另外一種方式,webservice,
它是一種基于SAOP協議的遠程調用標準，通過webservice可以將不同操作系統平臺，不同語言，不同技術整合到一起。說白了就是一種中間件技術.
我們在android客戶端中，有時需要一些庫，比如XFire,Axis2,CXF等等來支持訪問WebService，由于android sdk等并沒有提供這些庫,所以并不適合我們資源有限的android手機客戶端，這里有KSOAP這個第三方的類庫，可以幫助我們獲取服務器端 webService調用，KSOAP已經提供了基于android版本的jar包.
先下載KSOAP包：ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar包
然后新建一個android項目：并把下載的KSOAP包放在android項目的lib目錄下：右鍵->build path->configure build path--選擇Libraries，如圖：
以下分為七個步驟來調用WebService方法：
第一：實例化SoapObject 對象，指定webService的命名空間（從相關WSDL文檔中可以查看命名空間），以及調用方法名稱。
public final static String NAMESPACE = "http://tempuri.org/";
public static String wsdl ="http://jinhesoft.com/Service1.asmx";
private final static String defaultAddress ="jinhesoft.com";
private final static String defaultPage = "service1.asmx";
public final static String CONFIG_PATH = "/data/data/org.DigitalCM/DigitalCMWebserviceConfig.dat";
第二步：假設方法有參數的話,設置調用方法參數
request.addProperty("參數名稱","參數值");
第三步：設置SOAP請求信息(參數部分為SOAP協議版本號，與你要調用的webService中版本號一致):
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER10);
envelope.setOutputSoapObject(request);
// envelope.bodyOut = request;
第四步：構建傳輸對象，并指明WSDL文檔URL：
HttpTransportSE ht = new HttpTransportSE(wsdl);
第五步：調用WebService(其中參數為1：命名空間+方法名稱，2：Envelope對象):
ht.call(SOAP_ACTION, envelope);// 調用webservice（其中參數一SOAP_ACTION為命名空間+方法名，參數二為envelope）
第六步：解析返回數據：
resultObject = envelope.getResponse();// 第7步：使用getResponse方法獲得WebService方法的返回結果
原理和步驟過程了解后，我們下面結合具體項目實例給大家分享下,我們還是以之前的一篇文章: 登陸界面軟件自動更新功能的實現http://blog.csdn.net/jindegegesun/article/details/7232779
為例進行,簡化更改一個登陸過程。
1、新建一個登陸的布局界面
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<ScrollView
android:id="@+id/Main_LinearLayout"

</LinearLayout>
</ScrollView>
<LinearLayout

<Button

</Button>
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="@string/exit_text" >
</Button>
</LinearLayout>
</RelativeLayout>
第二步：建立登陸的Activity
package cn.jindegegesun.activity;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import org.DigitalCM.entities.UserInfo;
import org.ksoap2.serialization.SoapObject;
import cn.jindegegesun.util.PropertyUtil;
import cn.jindegegesun.webservice.WSObjectMapUtil;
import cn.jindegegesun.webservice.WSObjectUtil;
import cn.jindegegesun.webservice.WSUtil;
import cn.jindegegesun.webservice.WebServiceConfig;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.app.SearchManager.OnCancelListener;
import android.app.SearchManager.OnDismissListener;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
public class DigitalCity extends ContextActivity implements OnClickListener {
public final static int PROGRESS_DIALOG = 1;
public final static int DIALOG_LOGIN_FAIELD = 2;
public final static int DIALOG_CONNECT_ERROR = 3;
public final static int DIALOG_USER_PWD_EMPTY = 4;
public final static int DIALOG_EXIT_PROMPT = 5;
public final static int DIALOG_VERSION_UPDATE = 6;
private Button login = null;
private Button exit = null;
private EditText userCode = null;
private EditText password = null;
private CheckBox rememberpwd = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
findViews();
loadConfig();
setOnClickListener();
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
public void setOnClickListener() {
/* 為 Button 注冊點擊事件監聽對象，采用了匿名內部類的方式。 */
login.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
login();
}
}
);
/* 為 Button 注冊點擊事件監聽對象，采用了匿名內部類的方式。 */
exit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

}
});
}
public void findViews() {
userCode = (EditText) findViewById(R.id.user_code);

rememberpwd = (CheckBox)
findViewById(R.id.remember_pwd);
login = (Button) findViewById(R.id.login);
exit = (Button) findViewById(R.id.exit);
// outlineLogin = (CheckBox)
// contextActivity.findViewById(R.id.outline_login);
}
@SuppressWarnings("static-access")
public void login() {
new Thread(){
public void run(){
if (!validate(userCode.getText().toString(), password.getText()
.toString()));
Map<String, Object> params = new HashMap<String, Object>();
params.put("userName", userCode.getText().toString().trim()
.toLowerCase());
params.put("userPwd", password.getText().toString());
SoapObject result = null;
try {
result = WSUtil.getSoapObjectByCallingWS(
WebServiceConfig.NAMESPACE, "login", params,
WebServiceConfig.wsdl);
//log("SSSSSSSSSSSS");
} catch (Exception ex) {
showDialog(DIALOG_CONNECT_ERROR);
Log.e("Exception", ex.getMessage());
}
if (result == null) {
loginFailed();
}
WSObjectUtil wsObjectUtil = new WSObjectUtil();
SoapObject dataSet = null;
try {
dataSet = wsObjectUtil.getDataSetObject(result);
} catch (Exception e) {
loginFailed();
}
if (dataSet == null) {
loginFailed();
}
List<Map<String, Object>> rowMapList = WSObjectMapUtil
.getRowMapList(dataSet);
UserInfo.setUserInfo(rowMapList.get(0));
Intent intent =new Intent(DigitalCity.this,Main.class);
startActivity(intent);
}
}.start();
}
private Boolean validate(String user_code, String password) {
if (user_code == null || user_code.trim().equals("")
|| password == null || password.trim().equals("")) {
showDialog(DIALOG_USER_PWD_EMPTY);
return false;
}
return true;
}
public void loadConfig() {
Properties properties = PropertyUtil
.loadConfig(WebServiceConfig.CONFIG_PATH);
String username = properties.getProperty("username");
String pwd = properties.getProperty("password");
properties = PropertyUtil.loadConfig(WebServiceConfig.CONFIG_PATH);
username = properties.getProperty("username");
pwd = properties.getProperty("password");
if (pwd != null && !pwd.equals("")) {
rememberpwd.setChecked(true);
password.setText(pwd);
} else {
rememberpwd.setChecked(false);
}
userCode.setText(username);
}
private void loginFailed() {
showDialog(DIALOG_LOGIN_FAIELD);
}
private void exitApp() {
showDialog(DIALOG_EXIT_PROMPT);
}
@Override
protected Dialog onCreateDialog(int id) {
// TODO Auto-generated method stub
switch(id){
case LoginActions.DIALOG_LOGIN_FAIELD:
return new AlertDialog.Builder(this)
.setTitle(R.string.error_title)
.setMessage(R.string.login_failed)
.setPositiveButton(R.string.OK_text,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int arg1) {
// TODO Auto-generated method stub
dialog.cancel();
}
}).show();
case LoginActions.DIALOG_CONNECT_ERROR:
return new AlertDialog.Builder(this)
.setTitle(R.string.message_title)
.setMessage(R.string.connection_error)
.setPositiveButton(R.string.OK_text,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
}).show();
case LoginActions.DIALOG_USER_PWD_EMPTY:
return new AlertDialog.Builder(this)
.setTitle(R.string.message_title)
.setMessage(R.string.usercode_or_password_empty_warning)
.setPositiveButton(R.string.OK_text,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
}).show();
case LoginActions.DIALOG_EXIT_PROMPT:
return new AlertDialog.Builder(this)
.setTitle(R.string.message_title)
.setMessage(R.string.exit_prompt)
.setPositiveButton(R.string.OK_text,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
finish();
}
})
.setNegativeButton(R.string.cancel_text,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
dialog.cancel();
}
}).show();
}
return super.onCreateDialog(id);
}
}
第三步：新建一個登陸進入后的布局文件main.xml以及Main.Activity，這個類和界面都很簡單
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="hello,jindegege!"/>"
</LinearLayout>
package cn.jindegegesun.activity;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
public class Main extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//設置全屏
setContentView(R.layout.main);
}
}
第四步：添加程序所用的權限：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cn.jindegegesun.activity"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="7" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".DigitalCity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:label="@string/login_name"
android:name="cn.jindegegesun.activity.Main" >
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
注意：在第一個DigitalCity .activity的login()方法調用了webservice返回的數據，先貼出代碼；

} 以上的紅色字體部分就是具體調用webservice的具體步驟，最后一步，也就是第六步將會提供結果給調用webservice的方法，然后login()方法將通過
result = WSUtil.getSoapObjectByCallingWS(
WebServiceConfig.NAMESPACE, "login", params,
WebServiceConfig.wsdl);
得到第六步返回的結果。
當返回的結果與登陸界面輸入的帳號和密碼匹配后，登陸就成功了。
當然與服務器交互，這里還需要寫接口,關鍵是其中的sql語句，我是在visual studio 2008上用c#寫的一個login接口，如下：
[WebMethod(Description = "Android 接口： 登陸 userName 用戶名 userPwd 用戶密碼")]
public DataSet login(string userName, string userPwd)
{
DataSet ds = null;
string strSql = string.Format("select userid, username, password, deptid, realname, tel, email, usermemo, starttime, endtime, mapid, dwid, zw, deptname, purviewmid, dwmc from V_USERS t where t.username = '{0}' and t.password='{1}'", userName, userPwd);
try
{
RetStrSql(strSql);
ds = RetDataSet();
return ds;
}
catch (Exception ex)
{
//throw new Exception(ex.Message);
return null;
}
}
好的，基本就是這樣，貼上代碼共享地址：http://download.csdn.net/detail/jindegegesun/4070721
