=============================================
Create xml file main.xml
<?xml version="1.0" encoding="utf-8"?>
<ListView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:drawSelectorOnTop="true"
/>
==============================================
Create another xml named section_header.xml

<TextView   
    xmlns:android="http://schemas.android.com/apk/res/android"   
    android:layout_width="fill_parent"   
    android:layout_height="wrap_content"
