    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".TheDeveloperWorldIsYours" >

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/iv"/>
