Not setting / displaying in Fragment correctly

[casillic]

I can use circularSeekBar in a fragment which is displayed in via an activity fine. (The first fragment displayed.)
I have a problem when it is not the first fragment that is displayed. E.g.
If I had another Fragment displaying and I replace it with the one that contains the circularSeekBar. The circularSeekBar is display but not correctly. It appears it is not fully updated. I can touch it and then it corrects itself. What can I do to correct this. It appears it needs some type of refresh.

Okay, I've found the problem:
Change the onMeasure(int widthMeasureSpec, int heightMeasureSpec) as follows:

@OverRide
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    width = View.MeasureSpec.getSize(widthMeasureSpec);
    height = View.MeasureSpec.getSize(heightMeasureSpec);
