本文着重解决问题：
1 响应notification事件
2 实现获取notification内数据思路 

注意：manifest文件与主体文件中的绿色部分必须匹配，即获取消息后，根据action来判断是否为自己所需要的数据。
 
关于实现获取notification内数据的思路：
1）  在Activity 里注册接收广播，能直接设置TextView
缺点是 只有启动Activity 才能收到
2）  在Activity里注册全局广播
<receiver android:name=".SMSActivity$ReceiverSMS" >
     <intent-filter>
         <action android:name="android.provider.Telephony.SMS_RECEIVED" />
     </intent-filter>
</receiver>
3） 如你所写，在 onReceive创建本地储存（数据库等），在 Activity读取。
4） 在onReceive结束后，发送广播，在Activity接收。
