how you guys use java interface in kotlin,

I want to use following interface as annonymous instance.

public class NavigationView {
 public interface OnNavigationItemSelectedListener {
        public boolean onNavigationItemSelected(@NonNull MenuItem item);
    }
}

I guessed as below, apparently it does not work.

navigationView.setNavigationItemSelectedListener(_ : NavigationView.OnNavigationItemSelectedListener {
            override fun onNavigationItemSelected(item: MenuItem): Boolean {
                return onNavigationItemSelected_(item)
            }
        })

only creating concrete impl seems to work for me, which is a terrible idea.

class X : NavigationView.OnNavigationItemSelectedListener {
            override fun onNavigationItemSelected(item: MenuItem): Boolean {
                return onNavigationItemSelected_(item)
            }
        }
        
        navigationView.setNavigationItemSelectedListener(X())
