title: imageview not set full screen
body: <p>I set image view to full screen but it doesn't work: there is some space in between left and right side. How to set the <code>imageview</code> to full screen?</p>
  
  <p>this is my XML code:</p>
  
  
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"&gt;
      &lt;ImageView android:id="@+id/imageView"  
              android:layout_width="fill_parent"  
              android:layout_height="fill_parent"&gt;  
     &lt;/ImageView&gt;  
  &lt;/LinearLayout&gt;
  </code></pre>
