Answer 1

You can change the icon itself programmatically, using something like this:

toolbar.setNavigationIcon(R.drawable.new_icon);

Answer 2

Get the drawable

Drawable icMenu = ContextCompat.getDrawable(this, R.drawable.ic_hamburguer);

Tint the drawable

icMenu.setColorFilter(getResources().getColor(android.R.color.darker_gray), PorterDuff.Mode.SRC_ATOP);

Use it with the actionBar

actionBar.setHomeAsUpIndicator(icMenu);

actionBar.setDisplayHomeAsUpEnabled(true);

Or the toolbar

toolbar.setNavigationIcon(icMenu);
