I want to add navigation drawer in my activity that has a recycler view
If you need other xml file codes, tell me to put it here. MainPageActivity.kt
class MainPageActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener,CustomAdapter.OnItemClickListener {
lateinit var toolbar:androidx.appcompat.widget.Toolbar
lateinit var drawerLayout: DrawerLayout
lateinit var navView:NavigationView
private var data = arrayListOf<UserModel>()
private lateinit var myadapter:CustomAdapter
private val gson = Gson()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main_page)
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)
val recyclerview = findViewById<RecyclerView>(R.id.recycler_view)
recyclerview.addItemDecoration(SimpleDividerItemDecoration(this)) // for insert line divider to recyclerview items
}
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_message->{
Toast.makeText(this,"message clicked",Toast.LENGTH_SHORT).show()
}
R.id.nav_frinds->{
Toast.makeText(this,"frinds clicked",Toast.LENGTH_SHORT).show()
}
R.id.nav_update->{
Toast.makeText(this,"update clicked",Toast.LENGTH_SHORT).show()
}
R.id.nav_logout->{
Toast.makeText(this,"logout clicked",Toast.LENGTH_SHORT).show()
}
}
drawerLayout.closeDrawer(GravityCompat.START)
return true
}
}
activity_main_page.xml
<?xml version="1.0" encoding="utf-8"?>

I went ahead to create this navigation drawer according to the tutorials on YouTube Because I am a novice in the field of Android, no matter how hard I tried, I did not find the cause of the problem thank you
