Android: make the size of a custom view bigger than the size of screen

Question

enter image description hereI have a custom view and the user can draw rectangles(I used canvas). I would make the size of custom view bigger than the size of the screen. So, the user can draw not only in the size of screen. I tried ScrollView and NestedScrollView but they are not helpful to solve my problem.

What was wrong with ScrollView and NestedScrollView? – 1615903 Mar 11 '16 at 10:07 — 1615903, Mar 11 '16 at 10:07
just use `View#scrollBy` / `View#scrollTo` methods – pskink Mar 11 '16 at 10:57 — pskink, Mar 11 '16 at 10:57

As far as I could understand from this question is you want to make a canvas where someone can draw some pictures. So you need a bigger canvas to that user can drag the positions to left-right, up and down. If I understood correctly, then I would say, you might think of a different work-around instead of looking for a view bigger than the screen size.

You can think of an simple ImageView which will be auto zoomed-in and if the user clicks twice it'll zoom-out. The user can drag the positions of the ImageView whenever he wants.

Here's an SO answer about how you can implement the zoom in and out in an ImageView. Hope this will help to solve your problem.
