How can I add a search feature to the NoteUsingRoom application?

Hi everyone 👋

I’ve been exploring this NoteUsingRoom project and it helped me understand how Room Database works in Android.

I’m wondering how we could implement a search feature so users can easily find notes based on their title or content.

For example, if a user has many notes stored in the database, it would be helpful to filter them using a keyword.

What would be the best approach to implement a search feature using Room in this project?

Any suggestions or examples would be greatly appreciated.

Thanks!

One possible way to implement a search feature is by using a SQL query in the DAO interface.

For example, we can create a query like this:

@query("SELECT * FROM note_table WHERE title LIKE :query OR description LIKE :query")
fun searchNotes(query: String): LiveData<List>

Then we can call this function from the ViewModel and pass the search keyword entered by the user.

For instance:

viewModel.searchNotes("%" + keyword + "%")

This will filter the notes dynamically based on the text typed by the user.

Additionally, combining this with a SearchView in the UI would allow users to search notes in real time.

This feature would significantly improve the usability of the application, especially when there are many saved notes.
