    copied!<p>Create a 9patch png version of your image. This is an image where only certain areas can stretch. There is a tool in the android SDK <a href="http://developer.android.com/tools/help/draw9patch.html" rel="nofollow">have a look</a>. (You need to make the area to the left of the arrow the only part that stretches).</p> <p>Then use a frame layout with two Layouts inside; One for the bright blue background and one for the pointer. Eg:</p> <pre><code>&lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width/height/ect...&gt; &lt;LinearLayout android:id="BlueBackground" android:background="brightblue" android:layout_width/height/ect.../&gt; &lt;LinearLayout android:id="Pointer" android:background="pointer9patch" android:layout_width/height/ect...&gt; //The List &lt;/LinearLayout&gt; &lt;/FrameLayout&gt; </code></pre> <p><strong>EDIT:</strong></p> <p>If you want to the pointer menu to only take up a certain portion of the screen you can use a horizontal linearlayout to split the screen in two:</p> <pre><code> &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width/height/ect...&gt; &lt;ImageView android:id="BlueBackground" android:layout_width/height/ect...&gt; &lt;LinearLayout android:id="HSplitLayout" orientation="horizontal"&gt; &lt;LinearLayout android:id="Pointer" android:layout_width/height/ect...&gt; //The List &lt;/LinearLayout&gt; &lt;ContentOnRight...&gt; &lt;/LinearLayout&gt; &lt;/FrameLayout&gt; </code></pre>
