Fragment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);
