Android Tabs with interacting map and list views « Josh Thought
Last tutorial , we wrote a simple app that displays two interacting list views in a TabActivity . In this tutorial, we will up the ante and add a MapView as the content of one of the tabs.

An Android layout is a class that handles arranging the way its children appear on the screen. Anything that is a View (or inherits from View) can be a child of a layout.

The standard Layouts are: AbsoluteLayout FrameLayout LinearLayout RelativeLayout TableLayout
