android - How do I get the background color of a TextView?

How do I get the background color of a TextView?

When I press the TextView, I want to change the background color according to the background color that is in use.

TextView does not have a method such as:

getBackgroundResource()

Edit: I would prefer to get the resId of the background color.

If you want to get color code of the background try this:

if (textView.getBackground() instanceof ColorDrawable) {
    ColorDrawable cd = (ColorDrawable) textView.getBackground();
    int colorCode = cd.getColor();
}
