To create a new ArrayAdapter we must provide its constructor at least three things: The current context (represented by this), a layout for the list it will create, and the ArrayList of items it will be responsible for adapting into the ListView. To use the ArrayAdapter, we need to initialize it and attach it to the ListView whose list items it will be responsible for. Each item in the ArrayList is converted to an individual list item View object in our ListView layout. In this tutorial, we shall learn how to display elements of an array using Android ListView with the help of a Kotlin Android Application.

Kotlin Android ListView Example Android ListView is used to display items of an array as a scrollable list. One of the most common adapters in Android is the ArrayAdapter. Note: Don't worry about implementing the code seen in this lesson into MyRestaurants yet we'll walk through that process together in the next lesson. In Android, an adapter is essentially a bridge between the components of your user interface, and the data that your user interface should display. However, in order to get those items into that scrollable list, we need to use something called an adapter. This is android listview customization tutorial.We see how to customize a listview to have grouped headers and footer and display our images and text.
