Thank you for you answer! I guess that will do. But I found out important thing in API's, there are two methods related to this problem ( save and restore ) in Canvas class. Also, I played a bit around with rotation and there is another way to rotate only one shape on the canvas:
canvas.rotate(90, startX, startY); canvas.drawLine(...); canvas.rotate(-90, startX, startY); canvas.drawCircle(...); //Will not be rotated On Wednesday, September 12, 2012 8:43:38 PM UTC+3, bob wrote: > > How about this? > > > > final Matrix backup_matrix = canvas.getMatrix(); > > > // do whatever rotation, etc… drawing > > > > canvas.setMatrix(backup_matrix); > > > On Wednesday, September 12, 2012 11:02:15 AM UTC-5, NikDmit wrote: >> >> Thank you, for your response.
