ArrayIndexOutOfBoundsException with custom Android Adapter for multiple views in ListView



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,

  1. The item view type you are returning from getItemViewType() is >= getViewTypeCount().

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
