这种方式不用在配置文件加东西 

广播注册,可以写在Activity（onCreate）,也可以写在Fragment（onActivityCreated）里。

LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(getActivity());IntentFilter intentFilter = new IntentFilter();intentFilter.addAction("android.intent.action.CART_BROADCAST");//建议把它写一个公共的变量，这里方便阅读就不写了。BroadcastReceiver mItemViewListClickReceiver = new BroadcastReceiver() {            @Override            public void onReceive(Context context, Intent intent){                System.out.println("OK");            } }; broadcastManager.registerReceiver(mItemViewListClickReceiver, intentFilter);

发送广播

Intent intent = new Intent("android.intent.action.CART_BROADCAST");LocalBroadcastManager.getInstance(getActivity()).sendBroadcast(intent);
