Not able to set stroke_width programmatically

[jackthebeast]

I'm extending the class so I don't have to set all the styles every time I use it, but setting stroke width from my sub class doesn't work. Here's my complete class:

class CustomCircleProgressBar(context: Context, attributes: AttributeSet?) : CircleProgressBar(
    context,
    attributes
) {

    constructor(context: Context) : this(context, null)

    init {
        setStyle(SOLID_LINE)
        setProgressStartColor(getContext().getColor(R.color.colorAccent))
        setProgressEndColor(getContext().getColor(R.color.colorAccent))
        setProgressBackgroundColor(getContext().getColor(R.color.colorPrimaryLight))
        setProgressTextColor(getContext().getColor(android.R.color.transparent))
        setProgressStrokeWidth(TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 5, getResources().getDisplayMetrics()))
    } 
}

the stroke remains 1dp thin.
Works correctly if set from xml: app:progress_stroke_width="5dp"

Other parameters are working correctly. It appears to me that the problem is due to initPaint() not being called after the new width is set.
Any way I can make it work?
