How to change hamburger icon in Android (NavigationDrawer)

Question

Before write this thread I have try to implement the different solution that I found in stackoverflow, but nothing work properly.

I'm developing an Android applucation that use the custom navigation drawer, I have to change the standard icon of actionbar (now is toolbar, right ?), and settings icon.

This is my code:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setTitleTextColor(Color.parseColor("#009754"));
        setSupportActionBar(toolbar);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
    }

And this is what i try to implement:

This solution not work:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitleTextColor(Color.parseColor("#009754"));
toolbar.setNavigationIcon(R.drawable.ic_draw);
setSupportActionBar(toolbar);

This solution not work:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.ic_custom_drawer_icon);

I don't understand why i can't change the icon, i have no idea what's the problem...

If you're using the NavigationView with a DrawerLayout, you can set the hamburger icon programmatically like this;

 private fun setupToolbarWithCustomDrawerIcon() {
    val toggle = ActionBarDrawerToggle(
        this,
        binding.drawerLayout,
        binding.toolbar,
        R.string.navigation_drawer_open,
        R.string.navigation_drawer_close
    )

    binding.drawerLayout.addDrawerListener(toggle)
    toggle.syncState()
    binding.toolbar.setNavigationIcon(R.drawable.ic_drawer_menu)
}

Output:
