【J2ME】J2ME发送短信（单发与伪群发）

发送短信的关键代码如下：

MessageConnection mconn = null;
try {
mconn = (MessageConnection) Connector.open("sms://+8618688880000");
TextMessage m = (TextMessage) mconn
.newMessage(MessageConnection.TEXT_MESSAGE);
m.setAddress("sms://+8618688880000");
m.setPayloadText("短信内容");
mconn.send(m);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
mconn.close();
} catch (IOException e) {
e.printStackTrace();
}
}

以下是我写的一个工具类，可以调用sendSMS方法进行单发或者伪群发，参数里用到了一个自定义的监听器ISMSSenderListener ，该监听器给调用者提供回调，以便让调用者了解发送状态，码上：

import java.io.IOException;

import javax.microedition.io.Connector;
import javax.wireless.messaging.MessageConnection;
import javax.wireless.messaging.TextMessage;

send(lsn, numbers[i], msg);
try {
sleep(500);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}.start();
}

/**

*/
public static String formatNumber(String number) {
if (number.startsWith("+86")) {
return number.substring(3);
}
return number;
}

private static void send(ISMSSenderListener lsn, String number, String msg) {
MessageConnection mconn = null;
String addr = "sms://+86";
try {
number = formatNumber(number);
addr += number;
lsn.onSendStateChange(addr, ISMSSenderListener.SENDING);
Log.d(TAG, "发送短信，地址：" + addr);
mconn = (MessageConnection) Connector.open(addr);
TextMessage m = (TextMessage) mconn
.newMessage(MessageConnection.TEXT_MESSAGE);
m.setAddress(addr);
m.setPayloadText(msg);
mconn.send(m);

} catch (Exception e) {

Log.e(TAG, "发送出错：" + e.getMessage());
} finally {
try {
mconn.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
