Hi, That is why I gave you a complete working example ( maybe try it yourself ). But not knowing your code I could only guess about when you would want to call the saveView() method I provided.
I guess that you would call the saveView() method when the user requests that your KidsPaintView view should save their 'drawing' either to a file or to set as the wallpaper. I imagine that you would provide a menu option button, or some touchscreen or keyboard button to allow the user to trigger that action - when they had finished making their 'drawing'. I just used the trackball/dpad center button as an example to demonstrate triggering and saving the view. In my example I used 'SomeView' to represent your KidsPaintView and put the saveView() method in the Activity, but you could also put the saveView() method or some equivalent code inside your KidsPaintView view if you wish. You should also realize that you CAN just call draw( canvas ) on your KidsPaintView as your class extends View so it (automatically) inherits the View.draw( canvas ) method... You just need to ensure that you create and use a new canvas and a new bitmap when calling the draw( canvas) method, as I said originally and demonstrated with the code posted. Good luck !
