Android Studio: Set Color Tint on Icon within a TabItem

I'm using the TabLayout for my menu with Icon buttons. Is it possible to tint the icons via XML in drawables?

android:tint doesn't work with a TabItem element.

You can do it coding part, try this

private void setupTabIcons() {
    tabLayout.getTabAt(0).setIcon(tabIcons[0]);
    tabLayout.getTabAt(1).setIcon(tabIcons[1]);
    tabLayout.getTabAt(2).setIcon(tabIcons[2]);
    tabLayout.getTabAt(3).setIcon(tabIcons[3]);

    tabLayout.getTabAt(0).getIcon().setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_IN);
    tabLayout.getTabAt(1).getIcon().setColorFilter(Color.parseColor("#a8a8a8"), PorterDuff.Mode.SRC_IN);
    tabLayout.getTabAt(2).getIcon().setColorFilter(Color.parseColor("#a8a8a8"), PorterDuff.Mode.SRC_IN);
    tabLayout.getTabAt(3).getIcon().setColorFilter(Color.parseColor("#a8a8a8"), PorterDuff.Mode.SRC_IN);


    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            tab.getIcon().setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_IN);

        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            tab.getIcon().setColorFilter(Color.parseColor("#a8a8a8"), PorterDuff.Mode.SRC_IN);
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });
}
