Adding click events to a ListView in Android with Xamarin

This tutorial explains how to add click events to items on a list using an Android ListView in Xamarin. In this example, we have a list containing cities in Australia which was made in the previous tutorial. When individual list items are clicked/touched you can have a click event which might take the user to another screen or change the value of a variable, for example.

Step 1

Open the MainActivity.cs code from the previous tutorial (Creating a Simple ListView in Android with Xamarin) and after the myListView.Adapter = adapter; line start typing in myListView.ItemClick+= and press the spacebar. You will see a list of items to select. Double-click on the MyListView_ItemClick to create a new method of this name.

You will now have a new method called MyListView_ItemClick. This method will be called when any item on the list is clicked.

Step 2

Now add an if statement to check which item on the list was clicked/touched. For example, we could check if the ‘Sydney’ list item was clicked or touched. If it was, we can the run the appropriate code for that item. For example, we could take the user to another screen with information about Sydney.

Here is an example. You can just add if statements for each item if it is a small list. If it is a large list, you might like to find a more efficient way of doing it.

if (myListItems [e.Position] == "Sydney") {
                //  code to run when list item clicked goes here
            }

The code that you need to add is highlighted below.
