Try negating the height value `-(radius*2)` – IAmGroot Aug 03 '16 at 08:33

Document confusing me.It says"Draw the text, with origin at (x,y), using the specified paint. The origin is interpreted based on the Align setting in the paint." I set alignment left. – Dhrupal Aug 03 '16 at 08:49

1Looking at it properly you need to set the y value based on height of the canvas, same way you did the circle, then adjust it to be Below based on radius. `(getHeight() / 2) + radius`. One thing that may be confusing you is that the origion is the top left. And that increase in Y is downwards – IAmGroot Aug 03 '16 at 08:49

(getHeight() / 2) + radius worked. Thank you. – Dhrupal Aug 03 '16 at 08:53

You may need to add a few extra pixels based on text height. so (getHeight() / 2) + radius + 20
