Unable to get button background color-CodePudding

I am trying to obtain the current background color of a button from a randomized color palette. However, my app is always crashing when I try the following code.

int activeColor = ((ColorDrawable)color1.getBackground()).getColor();

I always get this error message.

CodePudding user response：

You need to cast it to RippleDrawable

int activeColor = ((RippleDrawable)color1.getBackground()).getColorStateList().getDefaultColor();
