body: <p>Im trying to create an adaptive layout containing a textview,listview and a button.Following is my code.</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"
      android:layout_margin="10dp"&gt;
  
      &lt;ListView
          android:id="@+id/selectedComplianceList"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_alignParentTop="true"
          android:layout_marginLeft="5dp"
          android:layout_marginRight="5dp"
          android:layout_marginTop="10dp"
          android:divider="@null"
          android:dividerHeight="6dp"
          android:clipToPadding="false"
          android:paddingTop="10dp"
          android:paddingBottom="10dp"
          android:layout_above="@+id/cont" /&gt;
  
     &lt;LinearLayout
         android:layout_width="match_parent"
         android:id="@+id/cont"
         android:orientation="vertical"
         android:layout_marginTop="3dp"
         android:layout_alignParentBottom="true"
         android:layout_alignParentLeft="true"
         android:layout_height="wrap_content"
         android:layout_marginLeft="10dp"
         android:layout_alignParentRight="true"
         android:layout_alignParentEnd="true"&gt;
         &lt;Button
             android:id="@+id/submit_area"
             style="@style/btn"
             android:layout_margin="2dp"
             android:layout_marginTop="5dp"
             android:layout_width="match_parent"
             android:text="Submit"
             android:padding="5dp"
             /&gt;
     &lt;/LinearLayout&gt;
  
      &lt;TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:textAppearance="?android:attr/textAppearanceMedium"
          android:text="ComplianceNames"
          android:id="@+id/textView2"
          android:layout_above="@+id/selectedComplianceList"
          android:layout_centerHorizontal="true" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>The textview has to be at the top of the listview and button should be at the bottom.</p>
  
  <ol>
  <li>Textview is not visible at the top. How can I make it visible</li>
  <li>Even though I have used divided height property, the listview items are not equally spaced enough. Moreover,if im setting the divider, the size of divider is high. How can I make it thin?</li>
  </ol>
