Besides the TextView view, which you will 
likely use the most often, there are some other basic controls that you will 
find yourself frequently using that is simple Button control. We can also styled 
the button using the system's default button background, which is often 
different from one device to another and from one version of the platform to 
another.
Basic Button : Represents a push-button 
widget
Lets look the examples of simple button's in 
Android
Step for creating Basic Button
	- Start new Android application
 
 ![create android application]() 
 
- Go to Main.axml and make following changes
 
 ![main.axml in android]() 
 
 <?xml
	
	version="1.0"
	encoding="utf-8"?>
 <LinearLayout
	
	xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 >
 <Button
 android:id="@+id/MyButton"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 />
 </LinearLayout>
 
- Go to Activity1.cs class make following 
	changes
 
 ![activity1.cs class in android]() 
 
 public
	class Activity1 
	: Activity
 {
 int count = 1;
 
 protected 
	override void OnCreate(Bundle 
	bundle)
 {
 base.OnCreate(bundle);
 
 SetContentView(Resource.Layout.Main);
 
 Button button = 
	FindViewById<Button>(Resource.Id.MyButton);
 
 button.Click += delegate { 
	button.Text = string.Format("{0} 
	clicks!", count++); };
 }
 }
 
 As above we create a simple button and create a button click event for it 
	when you click on the button it will count the click and display to the user
 
- Run the application
 
 ![simple button in android]() 
 
 Counting will increase automatically when you click on the button as you see above the counting was 3 now when you will click 3 more times on the button it will incease by 3 like below picture shows:
 
 ![simple button in android]() 
 
Thank You......
