Android调用Webservice实现…

1.2013年1月1日开始接触android开发,7月份就开始做第一份工作,以后会遇到解决掉的问题会及时写出来,以便于需要的人阅读,也当是我一个回顾和复习!

一,android调用C#写的WebService,服务端返回的是一个xml格式的数据,只需要解析xml即可!!下面贴出源码

1.就一个Activity,主要实现的功能就是获取布局文件输入传给服务器的值

public class MainActivity extends Activity {

    private EditTextnameEditText;

    private EditTextpassEditText;

    private TextViewtextView;

    private Buttonbutton;

    

    @Override

    public voidonCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       setContentView(R.layout.main);

       nameEditText = (EditText)this.findViewById(R.id.name);

       passEditText = (EditText)this.findViewById(R.id.pass);

       textView = (TextView)this.findViewById(R.id.textView);

       button = (Button)findViewById(R.id.button);

    }

    

    public void query(Viewv){

    String name =nameEditText.getText().toString();

    String pass =passEditText.getText().toString();

    try {

   

String address = AddressService.getAddress(name,pass);

String result = address.toString();

if (result.equals("true")) {

Toast.makeText(MainActivity.this, "跳转成功", 1).show();

}

textView.setText(address);

} catch (Exception e) {

e.printStackTrace();

Toast.makeText(getApplicationContext(), R.string.error,1).show();

}

    }

}

2.main.xml

<?xml version="1.0"encoding="utf-8"?>

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"

   android:orientation="vertical"

   android:layout_width="fill_parent"

   android:layout_height="fill_parent"

    >

    

    <EditText 

   android:layout_width="fill_parent" 

   android:layout_height="wrap_content" 

   android:id="@+id/name"

   android:hint="请填写用户名"

    />

    <EditText 

   android:layout_width="fill_parent" 

   android:layout_height="wrap_content" 

   android:id="@+id/pass"

   android:hint="请填写密码"

    />

    

   <Button

       android:id="@+id/button"

       android:layout_width="match_parent"

       android:layout_height="wrap_content"

       android:onClick="query"

       android:text="查询" />

    

    <TextView 

   android:layout_width="fill_parent" 

   android:layout_height="wrap_content" 

   android:id="@+id/textView"

    />

</LinearLayout>

3.服务器返回的数据也就是需要解析xml格式的数据(此段代码是webservicesoap1.2服务器返回的xml格式的数据)

<?xml version="1.0"encoding="utf-8"?>

<soap12:Envelopexmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema"xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">

 <soap12:Body>

    <loingxmlns="http://tempuri.org/">

     <name>$name</name>

     <pass>$pass</pass>

   </loing>

 </soap12:Body>

</soap12:Envelope>

4.使用pull方法解析xml数据(访问网络如果放在主线程里面会报NetWork错误,原因使android4.0以后不可以直接在主线程里面访问网络)

public class AddressService {

*/

public static String getAddress(String name,String pass)throws Exception{

String soap = readSoap();

soap = soap.replaceAll("\$name", name);

soap = soap.replaceAll("\$pass", pass);

byte[] entity = soap.getBytes();

String path ="###############";//API地址也就是webservice的访问地址

HttpURLConnection conn = (HttpURLConnection) newURL(path).openConnection();

conn.setConnectTimeout(5000);

conn.setRequestMethod("POST");

conn.setDoOutput(true);

conn.setRequestProperty("Content-Type", "application/soap+xml;charset=utf-8");

conn.setRequestProperty("Content-Length",String.valueOf(entity.length));

conn.getOutputStream().write(entity);

if(conn.getResponseCode() == 200){

return parseSOAP(conn.getInputStream());

}

return null;

}

private static String parseSOAP(InputStream xml)throwsException{

XmlPullParser pullParser = Xml.newPullParser();

pullParser.setInput(xml, "UTF-8");

int event = pullParser.getEventType();

while(event != XmlPullParser.END_DOCUMENT){

switch (event) {

case XmlPullParser.START_TAG:

//此处是pull解析xml由于我的项目返回的是一个boolean值,"logigResult"(截图看)

if("loingResult".equals(pullParser.getName())){

return pullParser.nextText();

}

break;

}

event = pullParser.next();

}

return null;

}

private static String readSoap() throws Exception{

InputStream inStream =AddressService.class.getClassLoader().getResourceAsStream("soap12.xml");

byte[] data = StreamTool.read(inStream);

return new String(data);

}

}

5.工具类

public class StreamTool {

public static byte[] read(InputStream inStream) throwsException{

ByteArrayOutputStream outputStream = newByteArrayOutputStream();

byte[] buffer = new byte[1024];

int len = 0;

while( (len = inStream.read(buffer)) != -1){

outputStream.write(buffer, 0, len);

}

inStream.close();

return outputStream.toByteArray();

}

}
