title: Center list item vertically on ListView
body: <p>I'm developing an Android application.</p>
  
  <p>On one activity I have a List with list items. Those list items will have a TextView (I'm using my own layout because probably I will need to add more widgets to it).</p>
  
  <p>This is ListActivity xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" &gt;
  
      &lt;ListView
          android:id="@android:id/list"
          android:layout_width="match_parent"
          android:layout_height="469dp"
          android:layout_marginLeft="20dp"
          android:layout_marginRight="20dp"
          android:layout_marginTop="40dp"&gt;
      &lt;/ListView&gt;
  
      &lt;RelativeLayout
          android:layout_width="fill_parent"
          android:layout_height="wrap_content" &gt;
          &lt;TextView
              android:id="@+id/orderErrorMsg"
              android:layout_alignParentRight="true"
              android:layout_alignParentBottom="true"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:padding="10dp"
              android:textSize="16dp" &gt;
          &lt;/TextView&gt;
      &lt;/RelativeLayout&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>And this is ListItem xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="100dp"
      android:orientation="vertical"&gt;
  
      &lt;TextView
          android:id="@+id/orderToFillName"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_gravity="center_vertical"
          android:textSize="20dp" /&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>And, finally, this is the result:</p>

  <p>Why TextView is not centered vertically?</p>
