        <solid android:color="@color/darkerGray" />
    </shape>
</item>
<item

    android:gravity="bottom|center_horizontal"
    android:top="50dp">
    <!--android:top="-40dp"-->

    <shape android:shape="oval">
        <solid android:color="#ffffffff" />
    </shape>
</item>
<item

    android:bottom="30dp"
    android:gravity="bottom">
    <shape android:shape="rectangle">

#. Update your custom drawable XML as below:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Container GRAY rectangle -->
    <item>
        <shape android:shape="rectangle">

            <size
                android:width="250dp"
                android:height="100dp" />

            <solid
                android:color="@android:color/darker_gray" />
        </shape>
    </item>

    <!-- Top WHITE oval shape -->
    <item
        android:left="-25dp"
        android:right="-25dp"
        android:top="-50dp"
        android:bottom="50dp">

        <shape android:shape="oval">

            <solid
                android:color="@android:color/white" />
        </shape>
    </item>
</layer-list>

#. Use this custom drawable in your layout as below:

<?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="match_parent"
    android:orientation="vertical"
    android:gravity="center_horizontal"
    android:background="@android:color/black"
    android:padding="16dp">

    <!-- Custom Footer -->
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/custom_shape">

    </LinearLayout>
</LinearLayout>
