Edges of ShapeDrawable oval (stroke-style) are cut (Android Studio)

Question

I'm new to Android Studio and at the moment I'm trying to create an oval (not solid, just stroke) of random color, stroke width and size programmatically:

        long randomSeedm = System.currentTimeMillis();
        Random random = new Random(randomSeedm);
        int[] color = {R.color.red, R.color.black, .....};

        int ovalWidth = 20 + random.nextInt(100);
        int ovalHeight = 20 + random.nextInt(100);

        ShapeDrawable shape = new ShapeDrawable(new OvalShape());
        shape.setIntrinsicWidth (ovalWidth);
        shape.setIntrinsicHeight (ovalHeight);
        shape.getPaint().setColor(getResources().getColor(color[random.nextInt(6)]));
        shape.getPaint().setStyle(Paint.Style.STROKE);
        shape.getPaint().setStrokeWidth(2+random.nextInt(15));
        shape.getPaint().setAntiAlias(true);

        ImageView oval = new ImageView(this);
        oval.setImageDrawable(shape);

Ater that I put the ImageView into a FrameLayout that covers the whole screen:

        FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ovalWidth, ovalHeight);
        left = random.nextInt(frameLayoutWidth - ovalWidth);
        top = random.nextInt(frameLayoutHeight - ovalHeight);
        params.leftMargin = left;
        params.topMargin = top;
        params.gravity = Gravity.TOP + Gravity.LEFT;

        frameLayoutWholeScreen.addView(oval, params);

The results are very satisfying (from my beginner's point of view), the only problem is that the edges of the ovals are partially cut. Here are some examples:

Example 2

Is there some way to avoid the cuts?

Answer 1

You need to add the value of the stroke when making the frame layout params.

    int strokeSize = 2 + random.nextInt(15);
    FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ovalWidth + strokeSize, ovalHeight + strokeSize);
    left = random.nextInt(frameLayoutWidth - (ovalWidth + strokeSize));
    top = random.nextInt(frameLayoutHeight - (ovalHeight + strokeSize));
    params.leftMargin = left;
    params.topMargin = top;
    params.gravity = Gravity.TOP + Gravity.LEFT;
    frameLayoutWholeScreen.addView(oval, params);
