How to Filter a RecyclerView with SearchView – Android Studio Tutorial



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.

  1. My book or library project

    I have activity_main that includes -listView –

    Row_itme includes textView

    Activity_web.xml includes webView

    Now 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 –

  2. All works Fine… But when I search and delete that item then whole recycler view items get removed, why ❓❓❓

  14. 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.
