Step 3: Describe the problem:

I Was trying to implement a search based on firestore and Firebase Firestore Paging adapter.
Each time when i change the query and called updateOptions() the recyclerview blinks and displays the items.

Steps to reproduce:

1. create new query in onQueryTextChange() of searchview and call updateOptions()

Observed Results:

The Recyclerview blinks while loading data

Expected Results:

The recyclerview should not blink like using notifyDataSetChanged()

Relevant Code:

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

          @Override
          public boolean onQueryTextChange(String newText) {
              if(!TextUtils.isEmpty(newText))
              {
                  search(newText);
                  return true;
              }
              return false;
          }
      });

private void search(String query)
  {
      if(TextUtils.isEmpty(query))
      {
          dbSearchQuery=quizRef.orderBy("searchText").startAt(query.toLowerCase()).endAt(query.toLowerCase()+"\uf8ff").whereEqualTo("uid",user.getUid());
      }
   
      options=new FirestorePagingOptions.Builder<QuizSearchModel>()
              .setQuery(dbSearchQuery, config, QuizSearchModel.class)
              .build();
      adapter.updateOptions(options);
  }
