RemoteCallbackList.beginBroadcast()

[HanteIsHante]

 int i = mRemoteCallbackList.beginBroadcast();
        while(i > 0){
            i --;
            try {
                mRemoteCallbackList.getBroadcastItem(i).dosomthing();
            } catch(RemoteException e) {
                e.printStackTrace();
            }
        }
        mRemoteCallbackList.finishBroadcast();

准备开始调用当前注册的回调。这将创建一个回调列表的副本,你可以从使用getBroadcastItem检索条目，注意:一次只能激活一个广播,所以你必须确保总是从同一个线程调用这个或者是自己做同步。完成后必须调用finishBroadcast。

数据传输到 Service 端的时候，数据对象已经是重新构造出来的了，因此，如果有注册监听器、注销监听器之类的需求，则不应该使用普通的 List 来管理。应使用 RemoteCallbackList 来处理接口。
