Networking 如何在blackberry中编写SMS应用程序？

谁能帮我写一个应用程序，在黑莓手机上收发短信。如果你能给我一些代码片段。

发送短信：

import net.rim.device.api.io.*;
import net.rim.device.api.system.*;
import javax.microedition.io.*;
import java.util.*;
import java.io.*;
public class SendSms extends Application
{
     private static final int MAX_PHONE_NUMBER_LENGTH = 32;
     private String addr = "15191112222";
     private String msg = "This is a test message.";
     private DatagramConnection _dc = null;
     private static String _openString = "sms://";
     public static void main(String[] args)
     {
          new SendSms().enterEventDispatcher();
     }
     public SendSms()
     {
          try {
               _dc = (DatagramConnection)Connector.open(_openString);
               byte[] data = msg.getBytes();
               Datagram d = _dc.newDatagram(_dc.getMaximumLength());
               d.setAddress("//" + addr);
               _dc.send(d);
          } catch ( IOException e) {}
          System.exit(0);
     }
}

要接收sms，请执行以下操作：

import net.rim.device.api.io.*;
import net.rim.device.api.system.*;
import javax.microedition.io.*;
import java.util.*;
import java.io.*;
public class ReceiveSms extends Application {
     private ListeningThread _listener;
     public static void main(String[] args)
     {
          new ReceiveSms().enterEventDispatcher();
     }
     ReceiveSms() {
          _listener = new ListeningThread();
          _listener.start();
     }
     private class ListeningThread extends Thread
     {
          private boolean _stop = false;
          private DatagramConnection _dc;
          public synchronized void stop()
          {
               _stop = true;
               try {
                    _dc.close();
               } catch (IOException e) {
                    System.err.println(e.toString());
               }
          }
          public void run()
          {
               try {
                    _dc = (DatagramConnection)Connector.open("sms://");
                    for(;;)
                    {
                         if ( _stop ) {
                              return;
                         }
                         Datagram d = _dc.newDatagram(_dc.getMaximumLength());
                         _dc.receive(d);
                         String address = new String(d.getData());
                         String msg = new String(d.getData());
                         System.out.println("Message received: " + msg);
                         System.out.println("From: " + address);
                         System.exit(0);
                    }
               } catch (IOException e) {
                    System.err.println(e.toString());
               }
          }
     }
}

从黑莓手机发送短信似乎并不总是那么简单。我想我已经弄明白了，但当黑莓用户在使用我正在使用的一款手机时，它就不起作用了

我找到了新的方法，并将其适应于此。与该示例不同的是端口号，我使用端口5016和

（其中555123123是好莱坞的电话号码。）

您没有在此处设置消息^^（数据！）

Hi Ashraf感谢您的帮助您可以提供代码来更新屏幕上收到的消息吗，因为我自己尝试过，但无法实现。您所说的“更新收到的消息”是什么意思？你能更详细地解释一下吗？嘿，阿什拉夫，我想在屏幕上显示收到的短信。怎么做？你可以用创建对话框对象（请参阅）或用简单的LabelField（请参阅）来替换“System.out.println”和“System.err.println”函数用户界面有很多选择。

private static byte[] stringToByte(String s)
{
    char[] sa = s.toCharArray();
    byte[] ba = new byte[sa.length];

    for (int i = 0; i < ba.length; i++) {
        ba[i] = (byte) (sa[i] & 0xFF);
    }

    return ba;
}

private static void sendCDMAText(String nr, String message) throws IOException
{
    DatagramConnection conn = (DatagramConnection) Connector.open("sms://+" + nr + ":5016");
    byte[] bytes = stringToByte(message);
    Datagram msg = conn.newDatagram(bytes, bytes.length);
    conn.send(msg);

}

private static void sendSMS(String nr, String message) throws IOException
{
    MessageConnection conn = (MessageConnection) Connector.open("sms://" + nr);
    TextMessage msg = (TextMessage) conn.newMessage(MessageConnection.TEXT_MESSAGE);
    msg.setPayloadText(message);
    conn.send(msg);
}

public static void sendTextMessage(String nr, String message) throws IllegalArgumentException, InterruptedIOException, NullPointerException, SecurityException, IOException
{
    if (RadioInfo.getNetworkType() == RadioInfo.NETWORK_CDMA) {
        sendCDMAText(nr, message);
        return;
    }

    sendSMS(nr, message);
}

sendTextMessage("555123123", "The little text message you wanted to send.");

public SendSms()
 {
      try {
           _dc = (DatagramConnection)Connector.open(_openString);
           byte[] data = msg.getBytes();
           Datagram d = _dc.newDatagram(_dc.getMaximumLength());
           d.setAddress("//" + addr);
           _dc.send(d);
      } catch ( IOException e) {}
      System.exit(0);
