title: Custom background color for RelativeLayout in Android is not working
body: <p>I am facing a problem where using custom background color for RelativeLayout, is not working. The problem does not occur when I use a primary color (like RED). Any pointers will be appreciated.</p>
  
  <p>I am pasting my view details here. It may not make sense as the map is not visible with this. But please ignore that bit. My concern is the background color.</p>
  
  <p><strong>What works :</strong></p>
  
  <pre><code>&lt;RelativeLayout
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:focusable="true"
      android:focusableInTouchMode="true"
      android:keepScreenOn="true" &gt;
  
      &lt;com.google.android.maps.MapView
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/mapview"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:clickable="true"
          android:apiKey="@string/map_key"/&gt;
  
      &lt;RelativeLayout
          android:id="@+id/friendListBackground"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:background="#FF0000"&gt;
          &lt;Button
              android:id="@+id/showAttendeesButton"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_alignParentBottom="true"
              android:layout_alignParentRight="true"
              android:drawableTop="@drawable/show_attendees_button" /&gt;
      &lt;/RelativeLayout&gt;
  &lt;/RelativeLayout&gt;
