相信用過諾基亞手機的朋友可能會記得，在短信發送之後，手機會顯示發送手機的狀態，Android同樣也提供了相應的功能，而且實現這個功能的方法也很簡單。
首先，我們需要在程序中注冊兩個權限：
1.接收短信的權限
2.發送短信的權限
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
之後，我們需要開啟兩個模擬器測試程序的功能，下面是實現的截圖，首先看第一張截圖，是一個模擬器接收到另一個模擬器發送來的短信顯示在通知欄裡：
我們會看到這個模擬器的端口號叫做5554，這個就相當於手機號，我們發送短信只要把這個號碼當做是手機號使用即可，下面這張截圖是主程序的實現截圖，點擊發送按鈕，短信被發出，同時，如果成功，系統會發送廣播信息。
截圖如下：
下面給出程序的實現代碼：
public class EX06_14 extends Activity
{
/* 建立兩個mServiceReceiver對象，作為類成員變量 */
private mServiceReceiver mReceiver01, mReceiver02;
private Button mButton1;
private TextView mTextView01;
private EditText mEditText1, mEditText2;
/* 自定義ACTION常數，作為廣播的Intent Filter識別常數 */
private static String SMS_SEND_ACTIOIN = "SMS_SEND_ACTIOIN";
private static String SMS_DELIVERED_ACTION = "SMS_DELIVERED_ACTION";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mTextView01 = (TextView)findViewById(R.id.myTextView1);

mEditText1 = (EditText) findViewById(R.id.myEditText1);
/* 短信內容 */
mEditText2 = (EditText) findViewById(R.id.myEditText2);
mButton1 = (Button) findViewById(R.id.myButton1);
//mEditText1.setText("+886935123456");
/* 設定預設為5556表示第二個模擬器的Port */
mEditText1.setText("5556");
mEditText2.setText("Hello DavidLanz!");
/* 發送SMS短信按鈕事件處理 */
mButton1.setOnClickListener(new Button.OnClickListener()
{
