Rounded corners in layout with custom color on Android

I've got an xml for the shape and color of my drawable :

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/light_red"/>
    <corners android:radius="10dp"/>
</shape>

But I would like to use this drawable as a global one, like having the corners rounded when I'm using it, but being able to change the backgroundColor.

But when I'm trying to change the backgroundColor programatically, it overrides the color like I want but it also override the rounded corners which becomes flat.

For the moment, if I want to have rounded corners with different colors, I need to create multiple XML files with only the android:color changing.

Just for other people coming here after, I did some research with what you gave me, this setColorFilter is deprecated since API 29.
I found the solution for non deprecated method (a little bit longer but working):

findViewById(R.id.your_xml_element).getBackground().setColorFilter(BlendModeColorFilterCompat.createBlendModeColorFilterCompat(Color.BLUE, BlendModeCompat.SRC_ATOP));

To programmatically change a color globally defined in a shape, use this:

findViewById(R.id.your_xml_element).getBackground().setColorFilter(Color.BLUE, PorterDuff.Mode.SRC_ATOP);
