Var xGoodList = xRoot.Descendants().ToList() įoreach (Good cg in xGoodList.Select(xGood => new Good(xGood)).Where(cg => !string.IsNullOrEmpty(cg.Description))) If (xRoot = null || !xRoot.HasElements) return constructor capable of creating a new list from XML public Goods(XElement xRoot) The Goods class represents a list of Good objects i.e.

The Good class represents a single item that will appear in the list. Next we need to implement the Good and Goods classes as these will form the basis of the article. To keep the article nice and simple I will use XML data to populate the list. The following example demonstrates how to display a very simple list of items. Very simple Adapter example - A list of items For example if the data contains a BIT type to represent a True / False condition, the developer can return the words TRUE or FALSE from the View rather than displaying it's raw BIT value.

The developer is able to manipulate the representation of the data before it is displayed. a View is returned for each row in the list of items.

When used to display a list of items, the Adapter will return a single View for each data item i.e. The Adapter class returns an instance of a View. A View is the basic building block for all UI components. In the world of Android development, all UI controls are collectively referred to as a View. The Adapter class is the bridge between the UI control and the data source.

Assumptionsįor the purposes of this article I will assume the reader is familiar with creating Android screen layouts and implementing classes in C#. The purpose of this article is to show you how you can populate an Android UI control with data using Xamarin.Android and Visual Studio. Android similarly allows the developer to populate UI controls with data, but there are differences in how you achieve this using Android. then you will be familiar with using UI controls and populating these controls at runtime from data from different sources. If you have developed Windows or Web applications using the. That may be data from a database, XML or other technology. For most Xamarin.Android applications you will want to display data of some sort.
