Java RecyclerView：未连接适配器；跳过布局

我在logcat中收到错误“未连接适配器；跳过布局”。但在我的手机上显示时似乎没有问题。我想知道是什么原因导致了错误

提前谢谢

OnCreate方法：

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_appbar);
    context=this;

    toolbar=(Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar);

    getSupportActionBar().setDisplayShowHomeEnabled(true);

    NavFragment drawerFragment = (NavFragment)
            getSupportFragmentManager().findFragmentById(R.id.nav_frag);
    drawerFragment.setUp(R.id.nav_frag, (DrawerLayout) findViewById(R.id.drawerLayout), toolbar);
    listEvents= new ArrayList<>();



    Parse.enableLocalDatastore(this);
    Parse.initialize(this, "xxxxxxxxxx", "xxxxxxxxxxx");

    //TEST PARSE

    ParseQuery<ParseObject> query = ParseQuery.getQuery("Test");
    //query.whereEqualTo("playerName", "Dan Stemkoski");
    query.findInBackground(new FindCallback<ParseObject>() {
        public void done(List<ParseObject> eventList, ParseException e) {
            if (e == null) {
                Log.d("Events", "Retrieved " + eventList.size() + " Events");

                for (int i = 0; i < eventList.size(); i++) {

                    Events events = new Events();
                    events.setTitle((String) eventList.get(i).get("teststr"));
                    events.setId(String.valueOf(eventList.get(i).get("teststr")));
                    listEvents.add(events);
                }
                eventAdapter= new EventAdapter(context);
                eventAdapter.setEventList(listEvents);
                eventsList.setAdapter(eventAdapter);
            } else {
                Log.d("score", "Error: " + e.getMessage());
            }
        }
    });


    eventsList=(RecyclerView)findViewById(R.id.list_events);
    eventsList.setLayoutManager(new LinearLayoutManager(this));

        layoutInflater=LayoutInflater.from(context);
    }

        this.listEvents=listEvents;
        notifyItemRangeChanged(0,listEvents.size());
    }

    @Override
    public ViewHolderEvents onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view=layoutInflater.inflate(R.layout.custom_event_row,viewGroup,false);
        ViewHolderEvents viewHolder =new ViewHolderEvents(view);

        return viewHolder;
    }

        Events currentEvent= listEvents.get(i);
        viewHolderEvents.title.setText(currentEvent.getTitle());

    }

        return listEvents.size();
    }

    static class ViewHolderEvents extends RecyclerView.ViewHolder{
        private TextView title;
        private TextView id;

        public ViewHolderEvents(View itemView) {

            id=(TextView)itemView.findViewById(R.id.description);
        }

这是因为您稍后将适配器连接到

RecyclerView

。您可以先设置空适配器，然后在获取数据时将数据填充到适配器

您可以查看的答案以供参考。

我遇到了同样的问题，并尝试了所有答案。然后我去吃午饭，打开电脑，那个错误就不再出现了。也许重启电脑可以解决问题？

你的应用程序崩溃了吗？如果是，你能发布详细的logcat报告吗？它不会崩溃。但我担心在logcat中看到“没有连接适配器；跳过布局”。。你能解释一下背后的原因吗。。
