I looked at the library. They do not have a setter for stroke_color. The only workaround here is to use Reflection to access this private field directly. Reflection is almost always a bad practice in java. But if you really want to do it, you can do it this way:

AnimCheckBox checkbox = (AnimCheckBox)findViewById(R.id.checkbox);
try{
  Field field = checkbox.getClass().getDeclaredField("mStrokeColor");
  field.setAccessible(true);
  field.setInt(checkbox,Color.parseColor("#2196F3"));
  checkbox.invalidate();
}
catch (NoSuchFieldException e){
  e.printStackTrace();
}
catch (IllegalAccessException e){
  e.printStackTrace();
}

You can set the circle color in the same way. For circleColor, the field name is mCircleColor.
