I can't find instructions to add a child item to my expandable list anywhere. All I can find is 50 questions on how to change the background color.

Right now, I am using this code to create a normal list view:

```
 public String listArray[] = { "Example1", "Example2", "Example3", "Example4", "Example5"}; 
 public void onCreate(Bundle savedInstanceState)
  {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main2);  
      listV = (ListView) findViewById(R.id.exListView);
      listV.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, listArray));      
  }    

```

But how would I go about adding sub or child items underneath example1, example2, etc..?
