Android – how do I set the toolbar background color in the activity to the color in the colors.xml file?

I have a color in my colors.xml file that I need to use for toolbar colors

<resources>
    <color name="MAIN_A">#f16264</color>
</resources>

Now I need to use main_ A as the color of the toolbar

resolvent:

Use this code

getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.white)));
