Apps Beginner List Help

[JosephTaylorC]

This code is directly from the Beginning Android 2 book and I cannot seem to get it to work. I do not know if it is outdated or not but I would really like to know why it does not work.

The purpose is to have a list of views, each with an image and some text.

public class DynamicDemo extends ListActivity {
TextView selection;
String[] items={"lorem", "ipsum", "dolor", "sit", "amet",
"consectetuer", "adipiscing", "elit", "morbi", "vel",
"ligula", "vitae", "arcu", "aliquet", "mollis",
"etiam", "vel", "erat", "placerat", "ante",
"porttitor", "sodales", "pellentesque", "augue",
"purus"};

@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
setListAdapter(new IconicAdapter());
selection=(TextView)findViewById(R.id.selection);
}

public void onListItemClick(ListView parent, View v,
int position, long id) {
selection.setText(items[position]);
}

class IconicAdapter extends ArrayAdapter {
IconicAdapter() {
super(DynamicDemo.this, R.layout.row, items);
}

public View getView(int position, View convertView,
ViewGroup parent) {
LayoutInflater inflater=getLayoutInflater();
View row=inflater.inflate(R.layout.row, parent, false);
TextView label=(TextView)row.findViewById(R.id.label);

label.setText(items[position]);

ImageView icon=(ImageView)row.findViewById(R.id.icon);

if (items[position].length()>4) {
icon.setImageResource(R.drawable.delete);
}
else {
icon.setImageResource(R.drawable.ok);
}

return(row);
}
}
}
