[android，10]10.調用web服務獲取手機號碼歸屬地

一、調用 web 服務獲取號碼歸屬地:

1、設置布局：

 

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

 

android:layout_width="fill_parent"

android:layout_height="wrap_content"

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

 

android:id="@+id/editText1"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:ems="10" >

 

 

 

android:id="@+id/button1"

android:onClick="query"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="Button" />

 

 

2、業務代碼：

public classDemoActivity extends Activity {

private EditText et_number;

@Override

public void onCreate(BundlesavedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

et_number = (EditText)this.findViewById(R.id.editText1);

}

 

public void query(View view){

Stringnumber = et_number.getText().toString().trim();

//web中的能獲取號碼歸屬地資源的地址

Stringpath =

"http://api.showji.com/Locating/20120413.aspx?m="+number+"&output=json";

try {

//請求地址

URL url = new URL(path);

HttpURLConnection conn = (HttpURLConnection)url.openConnection();

 

conn.setConnectTimeout(5000);

 

if(conn.getResponseCode()==200){

//

InputStream is = conn.getInputStream();

//獲取json格式的數據

String json = (new String(StreamTools.getBytes(is),"utf-8"));

JSONObject obj = new JSONObject(json);

System.out.println(json);

String text = (String) obj.get("City");

Toast.makeText(this,"歸屬地為 "+text, 0).show();

}

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

 

}

}
