Can't get my Button view to appear in a RelativeLayout

Question

In the code below (A custom list item) the Button view is not visible, it's like the ImageView takes all the place and not allow it to appear, how should I modify the code to make it appears at the bottom and rest of the space to be fore the ImageView?

    <RelativeLayout
        android:id="@+id/inner_container_layout" 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" 
        android:background="@drawable/background_with_shadow">

        <!-- Title -->
        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginLeft="8dp"
            android:layout_marginStart="8dp"
            android:layout_marginRight="25dp"
            android:layout_marginEnd="25dp"/>

        <!--  Sub Title -->
        <TextView
            android:id="@+id/sub_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginLeft="8dp"
            android:layout_marginStart="8dp"
            android:layout_below="@+id/title"/>

        <!-- Ad thumbnail -->
        <ImageView
            android:id="@+id/cover"
            android:background="@drawable/drop_shadow"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentStart="true"
            android:layout_alignParentLeft="true"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="8dp"
            android:layout_marginTop="5dp"
            android:layout_marginBottom="5dp"
            android:layout_below="@+id/sub_title"
            android:scaleType="fitXY"
            android:src="@android:color/transparent"/>

        <Button
            android:id="@+id/Button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/cover"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginLeft="8dp"
            android:layout_marginStart="8dp"
            android:text="Button"/>

    </RelativeLayout>

Just align your Button to your parent bottom and your ImageView above your Button. Something like this,

<RelativeLayout
        android:id="@+id/inner_container_layout" 
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" 
        android:background="@drawable/background_with_shadow">

        <!-- Title -->
        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginLeft="8dp"
            android:layout_marginStart="8dp"
            android:layout_marginRight="25dp"
            android:layout_marginEnd="25dp"/>

        <!--  Sub Title -->
        <TextView
            android:id="@+id/sub_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_marginLeft="8dp"
            android:layout_marginStart="8dp"
            android:layout_below="@+id/title"/>

        <!-- Ad thumbnail -->
    <ImageView
        android:id="@+id/cover"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_below="@+id/sub_title"
        android:layout_marginBottom="5dp"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:layout_above="@+id/Button"
        android:layout_marginTop="5dp"
        android:background="@color/colorAccent"
        android:scaleType="fitXY"
        android:src="@android:color/transparent"/>

    <Button
        android:id="@+id/Button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentBottom="true"
        android:layout_marginLeft="8dp"
        android:layout_marginStart="8dp"
        android:text="Button"/>

    </RelativeLayout>

Hope this will help you..!!
