Android手機歸屬地查詢工具

日期：2017/3/1 11:12:54 编辑：Linux編程

在Android應用中，我們經常會與網絡上的服務端的程序（J2EE或者.NET等應用）進行交互，通信。

本實例將向大家詳細介紹，在android中如何調用服務器端提供的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();
}
}
});
}
}

界面文件：

<?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：
