Android Toolbar color change

I have an app which uses android.support.v7.widget.Toolbar. Every section of the app is a Fragment accessed through a support.v4.widget.DrawerLayout

I need to change the Toolbar color depending on which section is shown (client particular needs).

I defined some colors in the colors.xml so I can make something like:

changeToolbarColor(R.color.section_one);

/**/

private void changeToolbarColor(int color_res_id){
    Integer colorTo = getResources().getColor(color_res_id);
    toolbar.setBackgroundColor(colorTo);
}

The problem is, once I do this, every view using the primaryColor (the original primary color from the toolbar) now shows up using the new color of the Toolbar.

So if my Toolbar was green and I change it to red, now everything using the old green uses red instead.

I suspect, that the change of the Toolbars background changes the primaryColor definition itself (which makes no sense to me). Because I have no other idea of how unrelated elements in unrelated activities start using the same color.

Is this a bug? Anyone with this problem? Any workarounds available?

Thanks for your help.

I guess (but not sure) that you should create different themes and recreate the toolbar depending on the selection, but probably this is not the best behavior – basteez
I thought about it @tizionario and I agree with you. It seems not the best approach. It looks like Toolbar's color has to be easy to change. But apparently it isn't, maybe using Palette or any other approach? But I can't think of a propper way of doing it right now. – Eloi Navarro

First of all themes are immutable, so it's not possible to change the primary color of the app.

And try using getSupportActionBar().setBackgroundDrawable().

I guess it's something else which is causing the issue. Can you post more code ?
