Android simple ListView and populate it with text data.

We create a class ListView and TextView using objects for each row.
Each name is a planet in the TextView.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
  
 <ListView android:layout_width="fill_parent" 
   android:layout_height="fill_parent" 
   android:id="@+id/mainListView">
 </ListView>
</LinearLayout> 

 mainListView = (ListView) findViewById( R.id.mainListView );  

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/rowTextView" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content"
 android:padding="10dp"
 android:textSize="16sp" >
</TextView>
