Dialog Fragment with wrap_content coming as a full screen. How to make it as a height of layout and not a full screen?

Question

I have created a custom dialog fragment and its xml as follows:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"

    android:padding="5dip" >

    <ListView
        android:id="@+id/product_list"
         android:background="@drawable/border_details"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
         />

    <RelativeLayout
        android:id="@+id/AddtoCart"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_marginTop="10dp"

        android:background="#005959" >

        <Button
            android:id="@+id/button_addToCart"
            android:layout_width="250dp"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:background="@drawable/gradient_button"
            android:layout_marginTop="2dp"
            android:layout_marginBottom="2dp"
            android:text="@string/add_to_cart"
            android:textColor="#000000" />
    </RelativeLayout>

</RelativeLayout>

When I call this Dialog, it is taking full screen as provided in the screenshot:

How do I restrict the size of this Dialog to the height of the list and the button?

How do I remove the excess white space?

Solved by changing RelativeLayout to LinearLayout and setting weight of list to 1 as follows

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="5dp"
   android:orientation="vertical"
    android:padding="5dip" >

    <ListView
        android:id="@+id/product_list"
         android:background="@drawable/border_details"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
         />
    <RelativeLayout 
    android:id="@+id/AddtoCart"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:layout_marginTop="10dp"
    android:background="#005959" >

    <Button
        android:id="@+id/button_addToCart"
        android:layout_width="250dp"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_marginBottom="2dp"
        android:layout_marginTop="2dp"
        android:background="@drawable/gradient_button"
        android:text="@string/add_to_cart"
        android:textColor="#000000" />

</RelativeLayout>
</LinearLayout>
