Working with canvas

Question

Hi everyone !!

I am able to draw a signature on my canvas. Now after that I want to save this signature as an image which can be used later.

I am unable to implement an onClicklistener on this canvas. Also I am unclear as to how this signature can be stored as an image. Please suggest?

Try this:

Bitmap bmp = Bitmap.createBitmap(...);
Canvas can = new Canvas(bmp);

When you change your canvas, bitmap bmp will change too. Canvas is only raference to Bitmap canvas, and you have no need to save canvas. Save only Bitmap (bmp).
