首先，我们需要在程序中注册两个权限：
1.接收短信的权限
2.发送短信的权限
之后，我们需要开启两个模拟器测试程序的功能，下面是实现的截图，首先看第一张截图，是一个模拟器接收到另一个模拟器发送来的短信显示在通知栏里：
我们会看到这个模拟器的端口号叫做5554，这个就相当于手机号，我们发送短信只要把这个号码当做是手机号使用即可，下面这张截图是主程序的实现截图，点击发送按钮，短信被发出，同时，如果成功，系统会发送广播信息。
截图如下：
下面给出程序的实现代码：
public class EX06_14 extends Activity
{
/* 建立两个mServiceReceiver对象，作为类成员变量 */
private mServiceReceiver mReceiver01, mReceiver02;
private Button mButton1;
private TextView mTextView01;
private EditText mEditText1, mEditText2;
/* 自定义ACTION常数，作为广播的Intent Filter识别常数 */
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);
/* 电话号码 */
mEditText1 = (EditText) findViewById(R.id.myEditText1);
/* 短信内容 */
mEditText2 = (EditText) findViewById(R.id.myEditText2);
mButton1 = (Button) findViewById(R.id.myButton1);
//mEditText1.setText("+886935123456");
/* 设定预设为5556表示第二个模拟器的Port */
mEditText1.setText("5556");
mEditText2.setText("Hello DavidLanz!");
/* 发送SMS短信按钮事件处理 */
mButton1.setOnClickListener(new Button.OnClickListener()
{
@Override
public void onClick(View arg0)
{
// TODO Auto-generated method stub
/* 欲发送的电话号码 */
String strDestAddress = mEditText1.getText().toString();
/* 欲发送的短信内容 */
String strMessage = mEditText2.getText().toString();
/* 建立SmsManager对象 */
SmsManager smsManager = SmsManager.getDefault();
// TODO Auto-generated method stub
try
{
/* 建立自定义Action常数的Intent(给PendingIntent参数之用) */
Intent itSend = new Intent(SMS_SEND_ACTIOIN);
Intent itDeliver = new Intent(SMS_DELIVERED_ACTION);
/* sentIntent参数为传送后接受的广播信息PendingIntent */
PendingIntent mSendPI = PendingIntent.getBroadcast(getApplicationContext(), 0, itSend, 0);
/* deliveryIntent参数为送达后接受的广播信息PendingIntent */
PendingIntent mDeliverPI = PendingIntent.getBroadcast(getApplicationContext(), 0, itDeliver, 0);
/* 发送SMS短信，注意倒数的两个PendingIntent参数 */
smsManager.sendTextMessage(strDestAddress, null, strMessage, mSendPI, mDeliverPI);
mTextView01.setText(R.string.str_sms_sending);
}
catch(Exception e)
{
mTextView01.setText(e.toString());
e.printStackTrace();
}
}
});
}
/* 自定义mServiceReceiver重写BroadcastReceiver监听短信状态信息 */
public class mServiceReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
// TODO Auto-generated method stub
//mTextView01.setText(intent.getAction().toString());
if (intent.getAction().equals(SMS_SEND_ACTIOIN))
{
try
{
/* android.content.BroadcastReceiver.getResultCode()方法 */
//Retrieve the current result code, as set by the previous receiver.
switch(getResultCode())
{
case Activity.RESULT_OK:
/* 发送短信成功 */
//mTextView01.setText(R.string.str_sms_sent_success);
mMakeTextToast
(
getResources().getText(R.string.str_sms_sent_success).toString(),
