Android Developer Documentation

  1. At the class level, create and initialize a rectangle variable. RectF is a class that holds rectangle coordinates in floating point.
private var rectF = RectF(
   rectInset,
   rectInset,
   clipRectRight - rectInset,
   clipRectBottom - rectInset
)
  1. Inside the class, implement the function drawRoundedRectangleClippingExample().

javascript private fun drawRoundedRectangleClippingExample(canvas: Canvas) { canvas.save() canvas.translate(columnTwo,rowThree) path.rewind() path.addRoundRect( rectF,clipRectRight / 4, clipRectRight / 4, Path.Direction.CCW ) canvas.clipPath(path) drawClippedRectangle(canvas) canvas.restore() }

What's happening in the code:

  • The addRoundRect() function takes a rectangle.
  • Values for the x and y values of the corner radius.
  • The direction to wind the round-rectangle's contour.
  • Path.Direction specifies how closed shapes (e.g. rects, ovals) are oriented when they are added to a path. CCW stands for counter-clockwise.

When you run your app it should look like this:
