Center ImageView in Relative Layout

Question

I have an image and a textview inside a relative layout. The image and the textview take up 50% of the screen width. How can I center the image and the textview ? I have tried many methods and I don't know what I'm doing wrong...

Here is my code:

        <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="100">
        <RelativeLayout
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="50"
            android:layout_centerHorizontal="true">

            <ImageView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:id="@+id/textViewEventImage"
                android:adjustViewBounds="true" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:background="@color/eventNameBackground"
                android:id="@+id/textViewEventName"
                android:textColor="@android:color/white"
                android:textSize="15sp"/>
        </RelativeLayout>
    </LinearLayout>
