 android:orientation="horizontal"
 android:layout_width="fill_parent"
    android:layout_height="fill_parent">
     <Button 
     android:id="@+id/welcomebutton"
     android:text="Welcome"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" />
    <TextView
     android:text="CreativeAndroidApps"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content" />
</LinearLayout>
