How to create image button in android?

So I'm new to android development...How can I create an image that acts like button, so when I press that image, image starts a specific activity. So I want this to show as image:

 <Button
    android:id="@+id/button1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_marginTop="33dp"
    android:text="Button" />
