android学习之webServiceXml--实现电话号码的归属地查询
本案例实现的是通过互联网实现对号码的归属地的查询，包括省份，城市，电话卡的类型！注意：在查询的时候，我用的是异步任务，这样的话主线程就不容易发生阻塞了；1.所需的权限：
<uses-permission android:name="android.permission.INTERNET"/>
2.布局文件：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<EditText
android:id="@+id/mobilePhone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="请输入电话号码"
/>
<Button
android:id="@+id/findPhone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="查询"
android:onClick="findPhone"
/>
<TextView
android:id="@+id/resultInfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="归属地查询" />
</LinearLayout>
2.要发送出去的xml文件，这里要说明的是，要想查询到数据的话，得向服务端发一个xml文件，然后服务端才会返回一个xml的结果；
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns: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>
<getMobileCodeInfo xmlns="http://WebXml.com.cn/">
<mobileCode>phone</mobileCode>
<userID></userID>
</getMobileCodeInfo>
</soap12:Body>
</soap12:Envelope>3.查询所需要的操作的类：
package com.example.webservice_test.utils;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import android.util.Xml;
import com.example.webservice_test.MainActivity;
public class WebServiceUtils {
public static String readXml() throws Exception
{
ByteArrayOutputStream bao = new ByteArrayOutputStream();
//获得类的加载器，得到xml文件的输入流
InputStream is = MainActivity.class.getClassLoader().getResourceAsStream("phonexml.xml");
byte[] buffer = new byte; //输入流的缓冲区
int len = -1;//标志
while((len = is.read(buffer)) != -1)//只要不等于-1的话就循环字节数组输出流中，其实也是在内存中
{
bao.write(buffer, 0, len);
}
is.close();
bao.close();
return new String(bao.toByteArray());
}
public static String getPhoneNumber(InputStream is) throws Exception
{
XmlPullParser parser = Xml.newPullParser();//实例化XnlPullParser解析器
parser.setInput(is, "utf-8");
//循环如果开始标签等于getMobileCodeInfoResult的话就返回里面的内容
for(int event=parser.getEventType(); event!=XmlPullParser.END_DOCUMENT; event=parser.next())
{
if(event== XmlPullParser.START_TAG && parser.getName().equals("getMobileCodeInfoResult"))
{
return parser.nextText();
}
}
return null;
}
public static String QueryPhoneArea(String path, String mobileNumber) throws Exception
{
String data = readXml().replace("phone", mobileNumber);
URL url = new URL(path);//链接地址
HttpURLConnection conn = (HttpURLConnection) url.openConnection();//打开链接
conn.setRequestMethod("POST");//请求方法
conn.setConnectTimeout(5000); //设置超时的时间
conn.setRequestProperty("Host", "webservice.webxml.com.cn");
conn.setRequestProperty("Content-Type", "application/soap+xml;charset=utf-8");
conn.setRequestProperty("Content-Length", data.length()+"");
conn.getOutputStream().write(data.getBytes()); //将电话号码发出去
int code = conn.getResponseCode();
if(code == 200)
{
InputStream is = conn.getInputStream(); //得到发回来的输入流
return getPhoneNumber(is); //获得信息
}
return null;
}
}
4.主程序的实现：
package com.example.webservice_test;
import com.example.webservice_test.utils.WebServiceUtils;
import android.os.AsyncTask;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
private EditText editText;
private TextView textView;
private String path;
private String mobileNumber;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.editText = (EditText) this.findViewById(R.id.mobilePhone);
this. textView= (TextView) this.findViewById(R.id.resultInfo);
}
public void findPhone(View v)
{
this.mobileNumber = this.editText.getText().toString();
Log.i("MainActivity", this.mobileNumber);
//所要访问的地址
this.path = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";
if(mobileNumber != null && !"".equals(mobileNumber))
{
findPhoneNumber();
}else
{
Toast.makeText(this,"请输入电话号码" +this.mobileNumber, Toast.LENGTH_SHORT).show();
}
}
public void findPhoneNumber()
{
new AsyncTask<Void, Void, String>(){ //异步任务
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
textView.setText("正在查询中...");
}
@Override
protected String doInBackground(Void... arg0) {
// TODO Auto-generated method stub
try
{
return WebServiceUtils.QueryPhoneArea(path, mobileNumber);
}catch(Exception e)
{
e.printStackTrace();
return null;
}
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
textView.setText(result);
super.onPostExecute(result);
}
}.execute();
}
}
你这是安卓的app ，发错地方了吧
