Android中用广播从Service中向Activity发送信息

http://blog.sina.com.cn/s/blog_773cd3e30100wzt7.html

1.在Service中发送广播
 

           Intent intent = newIntent( BroadcastAction);
             Bundlebundle = new Bundle();
            bundle.putString("***", SUCCESS);
            bundle.putString("FullPathName", mFullPathName);
            intent.putExtras(bundle);
            sendBroadcast(intent);
2.在Activity中创建一个内部类MyBroadcastReceiver扩展BroadcastReceiver，并在其中实现onReceive方法。
3.在Activity中声明一个MyBroadcastReceiver类型的成员变量，并注册：
    private MyBroadcastReceiver myBroadcastReceiver;
      ...
   myBroadcastReceiver = newMyBroadcastReceiver();
       IntentFilterfilter = new IntentFilter();
      filter.addAction( BroadcastAction);
      registerReceiver(receiver, filter);
4.使用完后要记得释放
      unregisterReceiver(receiver);

注：1和2中的 BroadcastAction要是同一个Action
