java - 广播接收器 onReceive 在 fragment 中不起作用

Question

我将 broadcastreceiver 从 Activity 发送到 fragment 。我的问题是 onReceive 不工作。

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup 
      container, Bundle savedInstanceState) {

    IntentFilter(Constants.BroadCastMessages.UI_NEW_CHAT_ITEM));

    onNotice = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            switch (action){

                case Constants.BroadCastMessages.UI_NEW_CHAT_ITEM:

                    Log.d("RokayahBroadcast" , "from on receive");
            }

        }
    };

  public void onResume() {
    super.onResume();

    IntentFilter iff = new 
       IntentFilter(Constants.BroadCastMessages.UI_NEW_CHAT_ITEM);
    LocalBroadcastManager.getInstance(getActivity()).registerReceiver(onNotice , iff);

   @Override
public void onPause() {
    super.onPause();
    getActivity().unregisterReceiver(onNotice);

请帮忙。提前致谢

据我所知，BroadcastReceiver 不能注册到 Fragment 中，而是注册到 Activity 中:您可能应该在 Activity 级别注册此接收器，然后在收到后将其传递给您的 Fragment。
