What is ListView?

Android ListView is a ViewGroup that is used to display the list of items in multiple rows and contains an adapter that automatically inserts the items into the list. The main purpose of the adapter is to fetch data from an array or database and insert each item that placed into the list for the desired result.

Which function is automatically called when the list item view is ready to be displayed?

The ListView instance calls the getView() method on the adapter for each data element. In this method the adapter creates the row layout and maps the data to the views in the layout. This root of the layout is typically a ViewGroup (layout manager) and contains several other views, e.g., an ImageView and a TextView .
