Answer 1

Creare un LinearLayout che è il figlio del layout radice e avvolge tutti gli altri layout e quindi modificare

<RelativeLayout 
android:id="@+id/relativeLayout0" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_centerHorizontal="true" 
android:layout_centerVertical="true" 
android:gravity="center" > 

a

<RelativeLayout 
android:id="@+id/relativeLayout0" 
android:layout_width="match_parent" 
android:layout_height="0dp" 
android:layout_weight="1" 
android:layout_centerHorizontal="true" 
android:layout_centerVertical="true" 
android:gravity="center_vertical|center_horizontal|center" > 

o aggiungere android:layout_above="@+id/relativeLayout1" a il tuo layout LOGO

Answer 2

Prova aggiungendo android:layout_above=@id/relativeLayout1 al layout del tuo logo.
