Introduction
Xamarin is a platform to develop cross-platform and multi-platform apps (for example, Windows phone, Android, iOS). In Xamarin platform, the code sharing concept is used. In Xamarin Studio, Visual Studio is also available.
Prerequisites
- Visual Studio 2015 Update 3.
The steps, mentioned below, are required to be followed in order to create an ImageButton in Xamarin Android app, using Visual Studio 2015.
Step 1
Click File--> select New--> select Project. The project needs to be clicked after opening all the types of projects in Visual Studio or click (Ctrl+Shift+N).
Step 2
After opening New Project, select Installed-->Templates-->Visual C#-->Android-->choose the Blank app (Android).

Step 3
Now, go to Solution Explorer. In Solution Explorer, get all the files and source in your project.
Now, select Resource-->Layout-->double click to open main.axml page. To write XAML code, you need to select the source.

Step 9
In this step, go to the Main.axml page source panel. Note the ImageButton's Id value.
Main.axml
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:minWidth="25px" android:minHeight="25px">
- <ImageButton android:src="@drawable/xamarin" android:layout_width="125.0dp" android:layout_height="111.5dp" android:id="@+id/ImageButton" android:layout_marginRight="0.0dp" android:layout_gravity="center" /> </LinearLayout>
Step 10 In this step, go to MainActivity.cs page and write the code, mentioned below, in OnCreate() Method.
MainActivity.cs - protected override void OnCreate(Bundle bundle) {
- base.OnCreate(bundle);
-
- SetContentView(Resource.Layout.Main);
- var button = FindViewById < ImageButton > (Resource.Id.ImageButton);
- button.Click += delegate {
- Console.WriteLine("button clicked");
- };
- }
Step 11 If you have an Android Virtual device, run the app on it, else, connect your Android phone and run the app on it.
Simply, connect your phone and go to Visual Studio. The connected phone will show up in the Run menu (Ex:LENOVO A6020a40(Android 5.1-API 22)). Click Run option.
Output After few seconds, the app will start running on your phone. You will see that the ImageButton is working successfully.
Summary
This was the process of how to create an ImageButton in Xamarin Android app, using Visual Studio 2015.
