Fragment间的广播消息接收

这种方式不用在配置文件加东西，我比较喜欢。

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);

intent怎么传参数就不用说了。
