title: Android activity border that can not be removed?
body: <p>So I have this</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    
      android:id="@+id/mainParent"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@drawable/bgdark"
      android:orientation="vertical" 
  &gt;
      &lt;ImageView
          android:id="@+id/imageView1"
          android:layout_width="match_parent"
          android:layout_height="76dp"
          android:src="@drawable/myheader_250x60" 
      /&gt;
      &lt;ListView
          android:id="@+id/mainListview"
          android:layout_width="match_parent"
          android:layout_height="match_parent" &gt;
      &lt;/ListView&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p><strong>Note</strong> I have now edited this post. I was using a grey background image, so I thought that was what was visible to right/left of header image.See below for an image showing the problem.</p>
  
  <p>However, moving the background to the listview did not solve the problem. Hence it would seem it is the imageview that somehow has a left/right border in grey. As i have set width to "match_parent" it should have taken he maximum width.</p>

  <p>The problem is that to the top/right of header there's a grey pixel border? which I would like to remove if possible. </p>
