Android 2.2 Credits Screen

Hi All, I am looking to have a credits screen developed for my Android 2.2 application. Basically I need this to look the same as the credits at the end of a movie would with text scrolling vertically down automatically. Once reaching the bottom of the available text the scroll should repeat from the top again. The text itself can be stored anywhere and initially can be whatever text information the dev would like to use but obviously this should be enough so that the screen can scroll through it. Ideally once the app is run it will launch to an activity which will have a button labelled Credits. When this is clicked it will load a dialog screen or launch another Activity. This will display a title 'Credits' and a back button at the top of the dialog screen (or at the top of the activity layout). The back button will return the user to the main activity. In the body of the screen the text will vertically scroll automatically. The vertical scroll bar should be invisible but the user should be able to manually scroll down or up. Thanks for taking the time to read this submission. Additional information and sample code can be provided. Regards, Cameron
