I hope this example will helpfull for you

Create /res/layout/row.xml

  <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/listtitle"
android:textSize="22px"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/listpubdate"
android:textSize="10px"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>

now create a class for using a cursor adapter in ListView
