Answer 1

Follow this steps :

Step 1: Create one background.xml file and put that file in drawable folder.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:bottom="20dp">
    <shape android:shape="rectangle" >
        <size android:height="100dp" />
        <solid android:color="#ffffff" />
    </shape>
</item>

<item android:top="300dp">
    <shape android:shape="rectangle" >
        <size android:height="10dp" />
        <solid android:color="#000000" />
    </shape>
</item>

Step 2 : In your Main.xml layout file.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keypad"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="@drawable/background">

Output :

Try

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#ffffff" />
        </shape>
    </item>

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#000000" />
        </shape>
    </item>
</layer-list>

Answer 3

Each ViewGroup can only have one background color, but you can easily achieve what you want by creating two ViewGroup elements.

Like.

<LinearLayout 
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">

<FrameLayout
   android:layout_width="0dp"
   android:layout_height="match_parent"
   android:layout_weight="1"

   android:background="#ff0000"/>

<FrameLayout
   android:layout_width="0dp"
   android:layout_height="match_parent"
   android:layout_weight="1"

   android:background="#00ff00"/>
