JAVA认证：在J2me程序里发送和接收短消息方法
WMA (Wireless Messaging API) 是在MIDP2.0里边定义的无线消息API, 它们主要是用来接收和发送基于文本、二进制和MultiPart格式的消息。/* 建立一个连接*/
public boolean connectSMSServer() {
try {
messageConnection messageConnection =
(MessageConnection) Connector.open("sms://:" + port);
messageConnection.setMessageListener(this);
} catch (Exception e) {
}
}
/* 发送文本短消息 */
public void sendTextmessage(String address, String message) {
try {
//生成一个新的短消息
TextMessage textMessage = (TextMessage) messageConnection.newMessage(
MessageConnection.TEXT_MESSAGE, address);
textMessage.setPayloadText(message);
messageConnection.send(textMessage);
} catch (Exception e) {
}
}
/* 接受文本短消息 */
public void receiveTextMessage() {
try {
Message message = messageConnection.receive();
if (message instanceof TextMessage) {
TextMessage textMessage = (TextMessage) message;
} else {
//Message can be binary or multipart
}
} catch (Exception e) {
}
}
/* 收到消息通知 */
public synchronized void notifyIncomingMessage(MessageConnection conn) {
//notiy thread of incoming message
synchronized (this) {
notify();
}
}
/* 关闭连接*/
public void closeConnection() {
if (messageConnection != null) {
try {
messageConnection.setMessageListener(null);
messageConnection.close();
} catch (Exception e) {
}
}
}
