How do I search for objects in the Android Fragment?

Question

I call a Fragment ListView in an activity and list the user records, and I want to do a search between those user records. Do I need a little little road show? How can I create this search feature?

Edit : I can describe my problem deeper because it can help.

You can simply filter items based on a property using Filterable interface if you are using ListView. You can find the implementation here : https://stackoverflow.com/a/24771174/7384780

It would be better to create a Database in your app and query from it (eg : RoomDB , sqllite ).
Use the DB as your single source of truth to display the items on your View . (This is where you could run your search queries for filtering and any other requirments)
Use Firebase to just populate your DB when the app is loading . This should run in an async thread. I would recommend using RxJava to better handle async functions.
For implementing search Feature , check below official search docs https://developer.android.com/guide/topics/search/ https://developer.android.com/training/search/setup
