Android设备接收到的SMS是以pdu形式的(protocol description unit)。android.telephony.gsm.SmsMessage这个类可以储存SMS的相关信息，我们也可以从接收到的pdu中创建新的SmsMessage实例，Toast界面组件可以以系统通知的形式来显示接收到的SMS消息文本。
A PDU is a "protocol discription unit", which is the industry format for an SMS message. because SMSMessage reads/writes them you shouldn't need to disect them. A large message might be broken into many, which is why it is an array of objects.
public class SMSReceiver extends BroadcastReceiver{/*当收到短信时，就会触发此方法*/public void onReceive(Context context, Intent intent){ Bundle bundle = intent.getExtras(); Object messages[] = (Object[]) bundle.get("pdus"); SmsMessage smsMessage[] = new SmsMessage[messages.length]; for (int n = 0; n < messages.length; n++) { smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]); } //产生一个Toast Toast toast = Toast.makeText(context, "短信内容: " + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG); //设置toast显示的位置 //toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 200); //显示该Toast toast.show();}}
