电话号码归属地查询

简单的电话号码归属地查询器

一、说明：仅供初学者借鉴，希望多多提意见，共同进步。

二、项目结构及界面图展示：

三、布局文件，较简单

</RelativeLayout>

四、代码：

package comcxrh.phonesearch;

import comcxrh.phonesearch.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.webkit.WebBackForwardList;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

private EditText et_phoneNumber;
private TextView tv_info;
private String phoneNumber;
private String path;
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  et_phoneNumber=(EditText) findViewById(R.id.et_phoneNumber);
  tv_info=(TextView) findViewById(R.id.tV_info);
}
/**
*按钮的监听事件
* @param v
*/
public void searchPhone(View v){
phoneNumber=et_phoneNumber.getText().toString().trim();
path="http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";
if(phoneNumber!=null && !"".equals(phoneNumber)){
   //查询号码
   getInternetData();
}else{
   Toast.makeText(this, "请输入电话号码", Toast.LENGTH_LONG).show();
}
   }
/**
* 用异步任务的方法，查询号码
*/
private void getInternetData(){
new AsyncTask<Void, Void, String>(){

  @Override
  protected void onPreExecute() {
   // TODO Auto-generated method stub
   tv_info.setText("正在查询，请稍后......");
   super.onPreExecute();
  }

  protected String doInBackground(Void... arg0) {
     try {
    return WebServiceUtils.queryPhone(path, phoneNumber);
   } catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }

   return null;
  }

  @Override
  protected void onPostExecute(String result) {
   // TODO Auto-generated method stub
   tv_info.setText(result);
   super.onPostExecute(result);
  }
}.execute();
}

}

另一个工具类：

package comcxrh.phonesearch.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 android.util.Xml;

import comcxrh.phonesearch.MainActivity;
public class WebServiceUtils {
   public static String queryPhone(String path,String phoneNumber) throws Exception{
    String data=readXml().replace("phone", phoneNumber);
    URL url=new URL(path);
  HttpURLConnection conn=(HttpURLConnection) url.openConnection();
  conn.setRequestMethod("POST");
  conn.setConnectTimeout(5000);
  conn.setRequestProperty("Host", "webservice.webxml.com.cn");
  conn.setRequestProperty("Content-Type", "application/soap+xml;charset=utf-8");
  conn.setRequestProperty("Content-Length", data.length()+"");
  conn.setDoOutput(true);
  conn.getOutputStream().write(data.getBytes());
  int code=conn.getResponseCode();
  if(code==200)
  {
   InputStream is=conn.getInputStream();
   return getPhoneNumber(is);
  }
  return null;
   }
   private static String getPhoneNumber(InputStream is) throws Exception {
    XmlPullParser parser=Xml.newPullParser();
  parser.setInput(is, "utf-8");
  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 readXml() throws IOException{
    ByteArrayOutputStream bao=new ByteArrayOutputStream();
    InputStream is=MainActivity.class.getClassLoader().getResourceAsStream("phonexml.xml");
    byte[] buffer=new byte[1024];
    int len=-1;
    while((len=is.read(buffer))!=-1){
     bao.write(buffer,0,len);
    }
    is.close();
    bao.close();
    return new String(bao.toByteArray());
   }
}
