Answer 5

Utilizzare questo nella vostra RelativeLayout

android:gravity="center_vertical"

Answer 6

È possibile utilizzare la gravità con l'allineamento superiore e inferiore.

android:gravity="center_vertical" 
android:layout_alignTop="@id/place_category_icon" 
android:layout_alignBottom="@id/place_category_icon"
