In this video we will learn how to use the SearchView widget to filter a RecyclerView in real time.
For this we will add the SearchView as an item to our options menu and make it expandable with the collapseActionView attribute. This way we can display it as an icon in our app bar, which expands to an input field when we click on it.
We implement the Filterable interface into our RecyclerView Adapter and create our own Filter, where we handle the filter logic in the asynchronous performFiltering method, which publishes the search results to the publishResults method on the UI thread.
In our Activity we then connect our SearchView with the Filter by setting an OnQueryTextListener onto our SearchView and listening for the text input in onQueryTextChange.

Thank you so much! Worked out perfectly
My book or library project
I have activity_main that includes -listView –
Row_itme includes
textViewActivity_web.xml includes
webViewNow I have master list titles, sub-menu titles, then documents or text
The files I have are in the -assets folder, there are also subfolders
Documents, texts, or book content are files – html-
For example 1.html – 2.html -3.html ….
Request: Add a search engine that accesses -html pages
Note that I applied a search engine, but it only works under -listView –
All works Fine… But when I search and delete that item then whole recycler view items get removed, why ❓❓❓
Still helpful video even it's very old 😊😊
I'm using a edittext to get the work done and it is working okay with TEXT WATCHER but how to get the full list if I clear the edittext?
Thank your help. I hope you make more videos <3

@Coding in Flow I have a question. I want to use this search view in separate activity. Suppose there is MainActivity which shows & implement Recyclerview and there is another acitivity named searchactivity which has one Edittext and I want user to type something in that Edittext and I want to use it as query to search in my listview which in in MainActivity. How can I achieve this? If you have some video about it, please share the name or link of that video. Thanks alot
Thanks! the best tutorial about the filterable recycler view, made my day.
Finally. A great explanation and to the point kind of video after a long time. Thumbs up. BTW, I wonder how much time you put on this video? You know, I am also a beginner kind of content creater so this interests me.
How can this be implemented with FirestoreRecyclerAdapter. I have tried with ArrayList and List but there re constructor errors. Please suggest
How can we inflate the menu from within a fragment? Thanks!
You deserve much more than just a like ✌🏻✌🏻
Whenever i need help i automatically come to your channel and search for the solution
Thank you so much man
What is the alternative of Searchview in actionViewClass attribute now in latest androidX
I am getting this error
java.lang.UnsupportedOperationException: This is not supported, use MenuItemCompat.getActionProvider()
on this line
val searchView: SearchView = searchItem.actionProvider as SearchView
i tried using
import android.widget.SearchView
and
import androidx.appcompat.widget.SearchView
Help.
Thanks a lot man! Clear and simple! I wonder if there is a way to filter diacritics from RecyclerView, do you have such an example? Thank you in advance!
I didn't get the ( app: actionViewClass = "android.support.v7.widget.SearchView" ). Anyone can help me?
THANKS !!!
I expected this on, onclick video…
i just copied the code and got this error;
Getting this Error….please help me with this;
java.lang.NullPointerException: Attempt to invoke virtual method 'void androidx.recyclerview.widget.RecyclerView.setAdapter(androidx.recyclerview.widget.RecyclerView$Adapter)' on a null object reference
Thanks so much for the video.
However, I have an issue…. when i search then it shows result, but if I try to use backspace or hit back button, the original RecyclerView is lost. And if suppose there are no matching results then the screen is just blank. Even if I press back button the screen is blank.
I understand that the original view is getting changed when I do notify dataset changed . How can I return to the original list.
I am using Room database and Live Data, which is made based on your tutorial of Arhitecture component.
It will be a real help if you can provide any solution. I have been trying to solve for last 3-4 days but couldn't do it.
Thanks in advance.
