Implementing a ListView

Almost all apps have some sort of collection of data that will be presented to the user, with the easiest and most common way being some sort of list.

How to do it...

If we want to present a collection of items to the user, we can use a ListView instance:

1. In order to show a list, we need to add a ListView element to our layout resource (we can do this in the code as well):

   <ListView
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:id="@+id/listView" />

2. We then get hold of the ListView instance in our code so that we can use it:

   ListView listView = FindViewById<ListView>(
     Resource.Id.listView);

3. Now that we have the view, we need the data (which we will generate here):

   IEnumerable<int> numbers = Enumerable.Range(1, ...
