Filter a recycler view with search view in Android

Question

I'm implementing the search view filtering logic on my recycler views in Android. My step is similar to what is discussed here .

It works, but the problem is when the query string is short, for example, empty string or single character string, it takes a the cursor freezes for about 1 second before I can type another character. I think this has something to do with the UI rendering (a lot more contacts are being rendered at this time).

Any idea on how to resolve this issue to make the filtering more smooth? Thank you for any advice in advance.

Edit: I have over 400 contacts in my phone. It works perfectly with less than 100 contacts.
