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

View

Here is my Home.java where i put the searchBar

public class Home extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

FirebaseDatabase database;
DatabaseReference product;

TextView userName;

RecyclerView recycler_prod;
