Android通过广播接收短信

public class MySMS extends BroadcastReceiver{    @Override    public void onReceive(Context context, Intent intent) {        if("android.provider.Telephony.SMS_RECEIVED".equals(intent.getAction())){            Log.i("test","收到短信了");            Bundle bundle=intent.getExtras();//得到intent对象            Object[] objects= (Object[]) bundle.get("pdus");//构建短信对象            SmsMessage[] messages=new SmsMessage[objects.length];//根据收到的对象创建长度            //根据收到的对象长度创建objects长度            for (int i = 0; i < objects.length; i++) {                //把每一个单元的pdu格式的短信转换成SmsMessage对象                messages[i] = SmsMessage.createFromPdu((byte[]) objects[i]);            }            for (SmsMessage message : messages) {                //获取对方的手机号码                String address=message.getOriginatingAddress();                //获取短信的内容                String body=message.getDisplayMessageBody();                Log.i("test",address+":"+body);            }        }    }}
