If I am not wrong, the fragment activity is something new for the latest version of Android ADT, and it is also the recommended way to develop Android applications. You can do whatever that is shown on the MainActivity to the fragment activity.

You can read more about fragments over here: http://developer.android.com/guide/components/fragments.html

If you want to concentrate on just the MainActivity instead of fragment, you can follow the instruction in this video: http://teamtreehouse.com/library/android-tools/getting-started-with-android-studio/fragments-and-layouts

Though it is shown in Android Studio, but the steps are similar to using Eclipse as well. Hope this help!

Thank you for your help! I figured out I should use the fragment xml.
