其实，要达到如题所述的效果很简单，只要注册一个广播，并设置该广播的intent-filter，同时把该intent-filter的优先级设置高于系统优先级

final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";

IntentFilter SMSfilter = new IntentFilter(SMS_RECEIVED);

SMSfilter.setPriority(1000);

最后，在onReceive方法的最后，用 this.abortBroadcast();来结束广播的继续发给别的程序，这样系统就不会收到短信广播了，Notification也不会有提示了

注意：这样是可以屏蔽通知栏里新短信的通知，但是，数据库中的新信息也就没有存在了……
