Add RelativeLayout with buttons below RecyclerView
<p>I need to add a RelativeLayout below my RecyclerView and was able to do so, except that the button under TOTAL(R.id.total_amount_tv) does not show:</p>

<p><a href="https://i.stack.imgur.com/0I5kT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/0I5kT.png" alt="enter image description here"></a> </p>

<p>I can easily scroll through the items and it doesn't affect my RelativeLayout. I just need the button to be visible.</p>

<pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/white"
    android:weightSum="1"&gt;

    &lt;android.support.v7.widget.RecyclerView
        android:id="@+id/order_recycler"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        tools:context=".ShoppingCartActivity" /&gt;

    &lt;RelativeLayout
        android:layout_width="match_parent"

        android:layout_marginBottom="10dp"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"&gt;

        &lt;TextView

        &lt;TextView

            android:layout_alignTop="@+id/total_tv"
            android:textSize="20sp"
            android:textStyle="bold|italic" /&gt;

        &lt;Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_below="@+id/total_amount_tv"
            android:layout_marginTop="51dp"
            android:background="@color/accent"
            android:onClick="onClickSendOrder"

            android:textColor="@android:color/white"
            android:textSize="20sp" /&gt;
    &lt;/RelativeLayout&gt;

&lt;/RelativeLayout&gt;
