回楼上：先写一个观察者：

 

public class SmsObserver extends ContentObserver {       
        private Context context;
        private static final String[] SMS_PROJECTION = new String[] {
               "address","person","date","type","body",
            };

        public SmsObserver(Context context,Handler handler) {
                super(handler);               
                this.context = context;
                Log.i("Leo-SmsObserver", "My Oberver on create");
        }
       
        public void onChange (boolean selfChange) {
                Log.i("SmsObserver", "sms onChange###### ");               
        }

}

 

然后在Acitivty或Service里注册这个观察者

 

getContentResolver().registerContentObserver(Uri.parse("content://sms"),
                                true, new SmsObserver(this, new Handler()));

 

当收发短信时，会调用onChange方法
