我正在使用jetpack导航组件来建立一个导航抽屉，我想改变工具栏的汉堡包图标，我尝试了很多像贝娄一样的解决方案，但都不工作

app:navigationIcon="@drawable/menu"

还

getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.menu);

这是我的密码

 override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    setSupportActionBar(toolbar)
    navController=findNavController(R.id.nav_host_fragment)
    appBarConfiguration=AppBarConfiguration(setOf(R.id.nav_acceuil,R.id.nav_notifications,R.id.nav_gerer,R.id.nav_deconnexion),drawer_layout)
    setupActionBarWithNavController(navController,appBarConfiguration)
    nav_view.setupWithNavController(navController);
}
