Android fill_parent issue
<p>HI there. This is my layout </p>

<pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"&gt;
    &lt;ListView android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@android:color/white" /&gt;
    &lt;Button android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:layout_below="@id/lv" /&gt;
&lt;/RelativeLayout&gt;
</code></pre>

<p>When I run this the list view occupies full screen. What I want is list view to be full screen except button area without mentioning dp. Thanks</p>
