17. Implement drawIntersectionClippingExample

Android Developer Documentation

• Canvas class

Here is the code:

private fun drawIntersectionClippingExample(canvas: Canvas) {
   canvas.save()
   canvas.translate(columnTwo,rowTwo)
   canvas.clipRect(
       clipRectLeft,clipRectTop,
       clipRectRight - smallRectOffset,
       clipRectBottom - smallRectOffset
   )
   // The method clipRect(float, float, float, float, Region.Op
   // .INTERSECT) was deprecated in API level 26. The recommended
   // alternative method is clipRect(float, float, float, float), which
   // is currently available in API level 26 and higher.
   if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
       canvas.clipRect(
           clipRectLeft + smallRectOffset,
           clipRectTop + smallRectOffset,
           clipRectRight,clipRectBottom,
           Region.Op.INTERSECT
       )
   } else {
       canvas.clipRect(
           clipRectLeft + smallRectOffset,
           clipRectTop + smallRectOffset,
           clipRectRight,clipRectBottom
       )
   }
   drawClippedRectangle(canvas)
   canvas.restore()
}

Note: The method clipRect(float, float, float, float, Region.Op.INTERSECT) was deprecated in API level 26. The recommended alternative method is clipRect(float, float, float, float), which is currently available in API level 26 and higher. So be sure to check the SDK version and use the appropriate API.

When you run your app it should look similar to this:
