Set Background color programmatically [duplicate]

Answer 1

In my case it wasn't changing the color because I was setting the color in my xml resource.

After delete the line that set the color it worked perfectly programmatically

This is an example I did in a RecyclerView

final Drawable drawable = ContextCompat.getDrawable(mContext, R.drawable.ic_icon).mutate();

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
    holder.image.setBackground(drawable);
} else {
    holder.image.setBackgroundDrawable(drawable);
}

If you just want to use some of the predefined Android colors, you can use Color.COLOR (where COLOR is BLACK, WHITE, RED, etc.):

myView.setBackgroundColor(Color.GREEN);

Otherwise you can do as others have suggested with

myView.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.myCustomGreen));

I don't recommend using a hex color directly. You should keep all of your custom colors in colors.xml.
