I am attempting to create a custom Adapter for my ListView since each item in the list can have a different view (a link, toggle, or radio group), but when I try to run the Activity that uses the ListView I receive an error and the app stops. The application is targeted for the Android 1.6 platform.

The code:

public class MenuListAdapter extends BaseAdapter {
 private static final String LOG_KEY = MenuListAdapter.class.getSimpleName();

 protected List<MenuItem> list;
 protected Context ctx;
 protected LayoutInflater inflater;

 public MenuListAdapter(Context context, List<MenuItem> objects) {
  this.list = objects;
  this.ctx = context;
  this.inflater = (LayoutInflater)this.ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
  Log.i(LOG_KEY, "Position: " + position + "; convertView = " + convertView + "; parent=" + parent);
  MenuItem item = list.get(position);
  Log.i(LOG_KEY, "Item=" + item );

        if (convertView == null)  {
            convertView = this.inflater.inflate(item.getLayout(), null);
        }

        return convertView;
 }

 @Override
 public boolean areAllItemsEnabled() {
  return false;
 }

 @Override
 public boolean isEnabled(int position) {
  return true;
 }

 @Override
 public int getCount() {
  return this.list.size();
 }

 @Override
 public MenuItem getItem(int position) {
  return this.list.get(position);
 }

 @Override
 public long getItemId(int position) {
  return position;
 }

 @Override
 public int getItemViewType(int position) {
  Log.i(LOG_KEY, "getItemViewType: " + this.list.get(position).getLayout());
  return this.list.get(position).getLayout();
 }

 @Override
 public int getViewTypeCount() {
  Log.i(LOG_KEY, "getViewTypeCount: " + this.list.size());
  return this.list.size();
 }

}

The error I receive:

    java.lang.ArrayIndexOutOfBoundsException
  at android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:3523)
  at android.widget.ListView.measureHeightOfChildren(ListView.java:1158)
  at android.widget.ListView.onMeasure(ListView.java:1060)
  at android.view.View.measure(View.java:7703)

I do know that the application is returning from getView and everything seems in order.

Any ideas on what could be causing this would be appreciated.

Thanks,
