Android ListView

Android ListView is a view which contains the group of items and displays in a scrollable list. ListView is implemented by importing android.widget.ListView class. ListView is a default scrollable which does not use other scroll view.

ListView uses Adapter classes which add the content from data source (such as string array, array, database etc) to ListView. Adapter bridges data between an AdapterViews and other Views (ListView, ScrollView etc).

Example of ListView

Let's implement a simple listview example.

Structure of listview project

Create an additional mylist.xml file in layout folder which contains view components displayed in listview.
