Android手機歸屬地查詢工具

在Android應用中，我們經常會與網路上的服務端的程式（J2EE或者.NET等應用）進行互動，通訊。
本執行個體將向大家詳細介紹，在android中如何調用伺服器端提供的webservice，實現典型的分布式應用。

package cn.itcast.mobile.address; 
 
import java.io.InputStream; 
 
import cn.itcast.service.MobileInfoService; 
import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.TextView; 
import android.widget.Toast; 
 
public class MainActivity extends Activity { 
    private EditText mobileText; 
    private TextView addressView; 
    private static final String TAG = "MainActivity"; 
     
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.main); 
         
        mobileText = (EditText)this.findViewById(R.id.mobile); 
        addressView = (TextView)this.findViewById(R.id.address); 
        Button button = (Button)this.findViewById(R.id.button); 
        button.setOnClickListener(new View.OnClickListener() {           
            @Override 
            public void onClick(View v) { 
                String mobile = mobileText.getText().toString(); 
                InputStream inStream = this.getClass().getClassLoader().getResourceAsStream("mobilesoap.xml"); 
                try { 
                    addressView.setText(MobileInfoService.getMobileAddress(inStream, mobile)); 
                } catch (Exception e) { 
                    Log.e(TAG, e.toString()); 
                    Toast.makeText(MainActivity.this, "查詢失敗", 1).show(); 
                } 
            } 
        }); 
    } 
} 

介面檔案：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    > 
<TextView   
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:text="@string/mobile" 
    /> 
     
    <EditText  
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:id="@+id/mobile" 
    /> 
     
    <Button 
     android:layout_width="wrap_content"  
    android:layout_height="wrap_content"  
    android:text="@string/button" 
    android:id="@+id/button" 
    /> 
     
    <TextView   
    android:layout_width="fill_parent"  
    android:layout_height="wrap_content"  
    android:id="@+id/address" 
    /> 
</LinearLayout> 

重點實現代碼：
