title: Using ImageView to hide/reveal another ImageView in RelativeLayout
body: <p>I want to display an image (image1 of 629x470 pixels) in a relative layout and use another complete white image (image2 of 1896x470 pixels) to scroll over image1 to hide/reveal image1.</p>
  
  <p>My image1 is visible correctly. But image2 is automatically resized to a smaller version and positioned vertically centered to image1 due to which I am not able to completely coverup image1. How do I display image2 as is so that it completely covers image1? 
  <em>adjustViewBounds</em> and <em>scaleType</em> did not help.</p>
  
  <p>My Layout is as follows:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;ImageView android:layout_height="wrap_content"
                 android:layout_width="wrap_content"
                 android:src="@drawable/image1" /&gt;
  
      &lt;ImageView android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:src="@drawable/image2" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>Please suggest.</p>
