onReceive没有为BroadcastReceiver调用

Question

我尝试在清单中注册广播接收器，但是没有调用onReceive方法。我做错了什么？

的manifest.xml

 <receiver
            android:name="zzz.yyy.xxx.ui.storyboard.discussion.DiscussionFragment$MessageCountReceiver"
            android:exported="true"
            android:enabled="true">
            <intent-filter>
                <action android:name="zzz.yyy.xxx.ui.storyboard.discussion.GROUPCHAT" />
            </intent-filter>
        </receiver>

发送广播如下：

Intent intent = new Intent("zzz.yyy.xxx.ui.storyboard.discussion.GROUPCHAT");
                intent.putExtra(BundleKeys.notification_post_id_forum,postId);
                LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

在Fragment类中接收广播，如下所示：

@Override
    public void onPause() {
        clearUnreadCount();
        LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(messageRefresher);
        super.onPause();
    }


    public class MessageCountReceiver extends BroadcastReceiver{

        @Override
        public void onReceive(Context context, Intent intent) {
            String noti_post_id = intent.getStringExtra(BundleKeys.notification_post_id_forum);

            int tempCount=PreferencesIMDStar.getIntValue(getActivity(),noti_post_id);
            tempCount++;
            PreferencesIMDStar.setIntValue(getActivity(),noti_post_id,tempCount);


            if (getActivity() != null && noti_post_id.equalsIgnoreCase(post_id)) {
                discussionPresenter.fetchCommentReply(post_id, true);
            }
        }
    }
