I'm using the library Material Search Bar to search my Firebase Database, but it doesn't work.
Right here is the layout and it is assumed that when I click on the search bar should give me some suggestions and also to look for products but it is not
My Firebase Database
Here is my Home.java where i put the searchBar
public class Home extends AppCompatActivity
