Android：實現手機號歸屬地查找的應用

原理：通過HTTP協議發送XML數據並調用webservice（soap）

首先定義string.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">手機號碼歸屬查詢</string>
<string name="mobile">手機號</string>
<string name="button">查詢</string>
<string name="error">連接失敗</string>
</resources>

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

<resources>

    <string name="app_name">手機號碼歸屬查詢</string>

    <string name="mobile">手機號</string>

    <string name="button">查詢</string>

    <string name="error">連接失敗</string>

</resources>

構建一個佈局：

view plain copy to clipboard print ?

<?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="wrap_content"
android:text="@string/mobile" />
<EditText
android:id="@+id/mobile"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<Button
android:id="@+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/button" />
<TextView
android:id="@+id/result"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>

<?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="wrap_content"

        android:text="@string/mobile" />

    <EditText

        android:id="@+id/mobile"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        />

    <Button

        android:id="@+id/button"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="@string/button" />

    <TextView

        android:id="@+id/result"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content" />

</LinearLayout>

效果圖：

然後編寫activity：

view plain copy to clipboard print ?

package cn.csdnmobile;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
import cn.csdn.service.MobileService;
public class MobileNumberBelongActivity extends Activity implements OnClickListener{
Button submitBtn ;
EditText numberEt;
TextView resultTv;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
findViews();
}
private void findViews() {
numberEt = (EditText) this.findViewById(R.id.mobile);
submitBtn = (Button) this.findViewById(R.id.button);
resultTv = (TextView) this.findViewById(R.id.result);
submitBtn.setOnClickListener(this);
}
//監聽，判斷並得到數據
public void onClick(View v) {
String PhoneNumber = numberEt.getText().toString().trim();
if(!"".equals(PhoneNumber)){
try {
//把數據傳給MobileService類中的getMobileBelong()方法
String result = MobileService.getMobileBelong(PhoneNumber);
//顯示經過上面的方法處理過後的數據
resultTv.setText(result);
} catch (Exception e) {
Log.e("TAG", e.toString());
Toast.makeText(this, R.string.error, Toast.LENGTH_LONG).show();
}
}
}
}

package cn.csdnmobile;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
import cn.csdn.service.MobileService;

public class MobileNumberBelongActivity extends Activity implements OnClickListener{
    
	Button submitBtn ;
	EditText numberEt;
	TextView resultTv;
	
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        findViews();
    }

	private void findViews() {
		numberEt = (EditText) this.findViewById(R.id.mobile);
		submitBtn = (Button) this.findViewById(R.id.button);
		resultTv = (TextView) this.findViewById(R.id.result);
		
		submitBtn.setOnClickListener(this);
	}

	//監聽，判斷並得到數據
	public void onClick(View v) {
		String PhoneNumber = numberEt.getText().toString().trim();
		
		if(!"".equals(PhoneNumber)){
			try {
				//把數據傳給MobileService類中的getMobileBelong()方法
				String result = MobileService.getMobileBelong(PhoneNumber);
				//顯示經過上面的方法處理過後的數據
				resultTv.setText(result);
			} catch (Exception e) {
				Log.e("TAG", e.toString());
				Toast.makeText(this, R.string.error, Toast.LENGTH_LONG).show();
			}
		}
		
	}
}

在得到輸入的數據後，要去交給傳給MobileService類中的getMobileBelong()方法處理，然後再把處理好的數據返回

            }

            event = parser.next();

        }

        return null;

    }

}

要調用webservice（soap），所以定義mobile_soap.xml

在MobileService.java 中調用此類轉換的語句：InputStream inStream = MobileService.class.getClassLoader().getResourceAsStream("mobile_soap.xml");

view plain copy to clipboard print ?

<?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>$mobile</mobileCode>
<userID></userID>
</getMobileCodeInfo>
</soap12:Body>
</soap12:Envelope>

<?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>$mobile</mobileCode>

      <userID></userID>

    </getMobileCodeInfo>

  </soap12:Body>

</soap12:Envelope>

在調用mobile_soap.xml 的時候，要把xml格式轉換成字節，所以在這裏要定義一個類

在MobileService.java 中調用此類轉換的語句：byte[] data = StreamTool.readInputStream(inStream);

view plain copy to clipboard print ?

package cn.csdn.utils;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
public class StreamTool {
/**
* 從輸入流讀取數據
* 把數據封裝到ByteArrayOutputStream
* 爲什麼要封裝：可以把它輕而易舉的做一個字節類型的轉換
*
* 然後返回
* @param inStream
* @return
* @throws Exception
*/
public static byte[] readInputStream(InputStream inStream)
throws Exception {
ByteArrayOutputStream outSteam = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = 0;
while ((len = inStream.read(buffer)) != -1) {
outSteam.write(buffer, 0, len);
}
outSteam.close();
inStream.close();
return outSteam.toByteArray();
}
}

package cn.csdn.utils;

import java.io.ByteArrayOutputStream;

import java.io.InputStream;

public class StreamTool {

    /**

     * 從輸入流讀取數據

     * 把數據封裝到ByteArrayOutputStream

     * 爲什麼要封裝：可以把它輕而易舉的做一個字節類型的轉換

     * 

     * 然後返回

     * @param inStream

     * @return

     * @throws Exception

     */

    public static byte[] readInputStream(InputStream inStream) 

            throws Exception {

        ByteArrayOutputStream outSteam = new ByteArrayOutputStream();

        byte[] buffer = new byte[1024];

        int len = 0;

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

            outSteam.write(buffer, 0, len);

        }

        outSteam.close();

        inStream.close();

        return outSteam.toByteArray();

    }

}
