@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    float width = (float) getWidth();

    float radius;

    if (width > height) {
        radius = height / 4;
    } else {
        radius = width / 4;
    }

    float center_x, center_y;
    final RectF oval = new RectF();

    center_x = width / 2;
    center_y = height / 2;

    oval.set(center_x - radius,
            center_y - radius,
            center_x + radius,
            center_y + radius);

    float percent = 25;
    float arcRadius = 360;
    float …
