(exception Resources$NotFoundException))ListView.layoutChildren() line: 1596

I am trying to create a list with a custom List item cell in a completely programatic way (without using any xml). I am running into below error. After several hours of searching on the web, I am writing this as my first question on Stack Overflow.

Appreciate your inputs on this & any suggestions on how to better handle Android programming without using the R.*.xml

On running this code, I get the below error:

(Suspended (exception Resources$NotFoundException))

ListView.layoutChildren() line: 1596

ListView(AbsListView).onLayout(boolean, int, int, int, int) line: 1112

ListView(View).layout(int, int, int, int) line: 6569

FrameLayout.onLayout(boolean, int, int, int, int) line: 333 ...

Code:

public class MyList extends ListActivity{

static final ArrayList<HashMap<String,String>> list = 
    new ArrayList<HashMap<String,String>>();

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

//CUSTOM LIST

    LinearLayout mainLayout=new LinearLayout(this);
    ListView myListView=new ListView(this);
    mainLayout.addView(myListView);


    LinearLayout ListItemLayout=new LinearLayout(this);
    TextView title = new TextView(this);
    TextView author = new TextView(this);
    TextView price = new TextView(this);
    ListItemLayout.addView(title);
    ListItemLayout.addView(author);
    ListItemLayout.addView(price);

    SimpleAdapter adapter = new SimpleAdapter(
        this,
        list,
        ListItemLayout.getId(),
        new String[] {"title","author","price"},
        new int[] {ListItemLayout.getChildAt(0).getId(),ListItemLayout.getChildAt(1).getId(),ListItemLayout.getChildAt(2).getId()}
    );     
    populateList();
    setListAdapter(adapter);  

}

private void populateList() {
    HashMap<String,String> map = new HashMap<String,String>();
    map.put("title",
"Professional Android ");
    map.put("author", "Meier");
    map.put("price", "$54.99");
    list.add(map);
    map = new HashMap();
    map.put("title","Android 2");
    map.put("author", 
"Sayed");
    map.put("price", "$48.98");
    list.add(map);
    }

}

You can't do that. SimpleAdapter requires a resource id from a layout defined in xml. It also requires the resource ids of the TextViews that it will be populating. This is because it uses LayoutInflater#inflate to create the containing View and then ViewGroup#findViewById to get the reference to the TextViews that will display the data.

If you want to do all your layout in code including that of the Adapter you will have to create your own custom Adapter class. You can do this by extending BaseAdapter and overriding getView at a minimum.

The constructor of your SimpleAdapter requires an id from your ListItemLayout but it doesn't have one (I guess the Android fall back is to check the R file), so assign it an id in your code.
