One of the UI component we use often is ListView, for example when we need to show items in a vertical scrolling list. One interesting aspect is this component can be deeply customized and can be adapted to our needs. In this first post i want to analyze the basic concepts behind it and how to use this component.

In order to show items inside the list, this component uses an adapter, so if we want to populate the list we have first create or use existing adapters. Android SDK has some standard adapters that are useful in many cases. If we have special needs we can create custom adapter and i will cover it in the next post. To understand how we can use this UI component we can suppose we want to show a list of planets. To make things simple and focus our attention on the ListView component we will use, by now

a very simple and basic adapter called SimpleAdaptehttp://www.tutorialspoint.com/android/android_drag_and_drop.htm
