Question

我正在寻找一种使用searchView在RecyclerView中过滤我的数据的方法，但仍然卡住了，我读过这篇文章Filtering a recyclerview with a firebaserecycleradapter和Filter data on firebase with Searchview，但没有任何明确的答案。而且他们是唯一可用的职位。

在这个问题上也没有明确的例子。

请大家帮我解决一下使用RecyclerView Firebase SearchView过滤数据的完整简单示例吗？

下面是Load()方法ic OnCreate()加载项目列表。

 void Load(){
        //   mAuth.addAuthStateListener(mAuthLitsener);

        FirebaseRecyclerAdapter<Event,EventViewHolder> firebaseRecyclerAdapter_ = new FirebaseRecyclerAdapter<Event, GraduationListActivity.EventViewHolder>(Event.class,
                R.layout.item_event_view,
                GraduationListActivity.EventViewHolder.class,
                queryRef) {
            @Override
            protected void populateViewHolder(GraduationListActivity.EventViewHolder viewHolder, final Event model, final int position) {
                final String key_post = getRef(position).getKey();
                viewHolder.setEventLocation(model.getEventLocation());
                viewHolder.setEventName(model.getEventName());
                viewHolder.setEventType(model.getEventType());
                viewHolder.setEventDate(model.getEventDate());
                viewHolder.setEventPic(c, model.getEventImage());
                viewHolder.mView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        // Toast.makeText(EventViewActivity.this,"This is : "+position,Toast.LENGTH_LONG).show();

                        Intent loadMainActivity = new Intent(GraduationListActivity.this,BlogActivity.class);
                        loadMainActivity.putExtra("PARTY_NAME", model.getEventName());
                        startActivity(loadMainActivity);
                    }
                });
            }
        };

        mRecyclerview_event_view.setAdapter(firebaseRecyclerAdapter_);
    }

这是我的onCreateOptionsMenu()

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater menuInflater = getMenuInflater();
        menuInflater.inflate(R.menu.search, menu);

        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
                // ????????
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                //??????
                return true;
            }
        });

        return super.onCreateOptionsMenu(menu);
    }

所以我使用searchView进行搜索但很困惑：根据Firebase，我应该将onQueryTextChange()和onQueryTextSubmit()放入什么内容？

onQueryTextChange + FirebaseAdapter
