title: Background colour of sliding drawer
body: <p>I am currently working on an android project and making use of the SlidingDrawer but I  am having a problem with changing the background colour. </p>
  
  <p>By default the SlidingDrawer appears to be transparent so when it is slid up over the content it is hard to read the content of the slidingdrawer due to the main screen being shown underneath. </p>
  
  <p>I wanted to change the background colour to black but for some reason this changes the background colour of the main content so you can't see any of the content and only the content of the sliding drawer when it is pushed up the screen. </p>
  
  <p>Below is the code that I have used to generate the sliding drawer</p>
  
  <pre><code>&lt;SlidingDrawer 
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:id="@+id/drawer"
          android:handle="@+id/handle"
          android:content="@+id/content"
          android:background="@color/black"&gt;
          &lt;ImageView 
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:id="@+id/handle"
              android:src="@drawable/ic_launcher"/&gt;
          &lt;LinearLayout 
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:orientation="vertical"
              android:id="@+id/content"&gt;
          &lt;TextView 
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="I am a sliding drawer - Hello World"/&gt;
          &lt;/LinearLayout&gt;
      &lt;/SlidingDrawer&gt;
  </code></pre>
  
  <p>Thanks for any help you can provide.</p>
