title: How to add multiple coloring pages in basic Android drawing app?
body: <p>I am completely new here and to developing apps. I following a basic tutorial:
  <a href="http://code.tutsplus.com/tutorials/android-sdk-create-a-drawing-app-interface-creation--mobile-19021" rel="nofollow">http://code.tutsplus.com/tutorials/android-sdk-create-a-drawing-app-interface-creation--mobile-19021</a></p>
  
  <p>It has three parts to the tutorial. But eventually you have an app that can draw with multiple colors, can erase, save, change the brush size and start with a new canvas.</p>
  
  <p>My aim is to add an option for the user to choose a background for the canvas. I have already set a drawable to be the background for the canvas currently used. So that the kids can "color in". I now want to add a button which lets that change the background of the canvas. I would like to let them choose between 9 different "templates"</p>
  
  <p>As the app has many different pieces of code, and i dont know exactly which one to paste here, please go to the tutorial page to see all the code that was used. OR just ask me which part to paste in here.</p>
  
  <p>Sorry if I am being unclear or vague, but im really an early beginner.</p>
  
  <p>Thanks so much.</p>
