android 注册广播代码（备用）

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);
