Scale and position a path in a custom View in Android

Question

I'm using a custom View so the user can draw on the screen. I'm using the Path class and everything works out.

When the orientation change, the custom View width and height changes too. My question would be if there is a way to scale the path according to the new View size, and position it relatively too.

PS: for anyone wondering how did I save the path for orientation change, all credits to Rabie Jradi how to serialize an object of android.graphics.Path

You can use this to scale path.

Matrix scaleMatrix = new Matrix(); scaleMatrix.postResize(orginalWidth/currentWidth, orginalHeight/currentHeight); path.transform(scaleMatrix);

There is no Matrix.postResize() method. There is a setScale() method. – Dave Hubbard Apr 04 '18 at 19:46
Maybe i meant postScale() or API changed in 4 years. Honestly I don't even remember i wrote this. – Onur Apr 04 '18 at 20:30
