title: Android Multi-Screen Application
body: <p>How do you handle multiple screens in an android application?  I have developed with the tab bar at the bottom without problem, however what I am wanting to do is replace all the content on the screen with the content from a new .xml layout file I have created in the project.  Additionally, how would I tie the back end code to the new layout file?  I'm sure this question probably exists already and is googleable (may have made up a new word).  However, I don't know exactly what it is that I am looking for.  Thanks in advance for your help.</p>
