But, if I use the customview in the xml, the onDraw() function only goes through once on start and cannot be invalidate()'d.
This is the layout XML:

circleView = new CircleView(this);
loads the class outside of the XML, which was part of the problem. However, when I tried to load the view by findViewById() I got a NullPointerException. So, the setContentView({Your layout XML}) needs to be called before trying to get the class by view. AKA solution is:
