title: ArrayIndexOutOfBoundsException with custom Android Adapter for multiple views in ListView
body: <p>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. </p>
  
  <p>The code:</p>
  
  <pre><code>public class MenuListAdapter extends BaseAdapter {
   private static final String LOG_KEY = MenuListAdapter.class.getSimpleName();
  
   protected List&lt;MenuItem&gt; list;
   protected Context ctx;
   protected LayoutInflater inflater;
  
   public MenuListAdapter(Context context, List&lt;MenuItem&gt; 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();
   }
  
  }
  </code></pre>
  
  <p>The error I receive:</p>
  
  <pre><code>    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)
  </code></pre>
  
  <p>I do know that the application is returning from <code>getView</code> and everything seems in order.</p>
  
  <p>Any ideas on what could be causing this would be appreciated.</p>
  
  <p>Thanks,</p>
