this is my code:

import android.os.Bundle
import android.view.MenuItem
import android.widget.Toast
import androidx.fragment.app.Fragment
import android.widget.Toolbar
import androidx.appcompat.app.ActionBarDrawerToggle
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.GravityCompat
import androidx.drawerlayout.widget.DrawerLayout
import com.google.android.material.navigation.NavigationView

/**
 * A simple [Fragment] subclass.
 */
class FragmentHome : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {
    lateinit var toolbar: Toolbar
    lateinit var drawerLayout: DrawerLayout
    lateinit var navView: NavigationView
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_home)

        toolbar = findViewById(R.id.toolbar)
        setSupportActionBar(toolbar)

        drawerLayout = findViewById(R.id.drawer_layout)
        navView = findViewById(R.id.nav_view)

        val toggle = ActionBarDrawerToggle(
            this, drawerLayout, toolbar, 0, 0
        )

        drawerLayout.addDrawerListener(toggle)
        toggle.syncState()
        navView.setNavigationItemSelectedListener(this)
    }

    override fun onNavigationItemSelected(item: MenuItem): Boolean {
        when (item.itemId) {
            R.id.nav_profile -> {
                Toast.makeText(this, "Profile Clicked", Toast.LENGTH_SHORT).show()
            }
            R.id.nav_messages -> {
                Toast.makeText(this, "Messages clicked", Toast.LENGTH_SHORT).show()
            }
                R.id.nav_friends -> {
                    Toast.makeText(this, "Friends clicked", Toast.LENGTH_SHORT).show()
                }
                R.id.nav_update -> {
                    Toast.makeText(this, "Update clicked", Toast.LENGTH_SHORT).show()
                }
            }
            drawerLayout.closeDrawer(GravityCompat.START)
                return true
        }
    }

this is my eror: 

 Type mismatch: inferred type is android.widget.Toolbar but androidx.appcompat.widget.Toolbar? was expected

Remove " import android.widget.Toolbar" and add please : import androidx.appcompat.widget.Toolbar YOUR problem will be solved. Thank you!!!

I was also facing this problem

Thanks a lot Pankaj. This worked for me.
