Problema de LayoutInflater de Android

Aquí está el método getView de mi clase DownloadableProjectsFromWebAdapter:

@Override public View getView(int position, View convertView, ViewGroup parent) { View row = convertView; DownloadableProjectsFromWebHolder holder = null; if(row == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); row = inflater.inflate(layoutResourceId, parent, false); holder = new DownloadableProjectsFromWebHolder(); holder.txtPid = (TextView)row.findViewById(R.id.tvAllProjectsPid); holder.txtName = (TextView)row.findViewById(R.id.tvAllProjectsName); holder.txtShareable = (TextView)row.findViewById(R.id.tvAllProjectsShareable); row.setTag(holder); } else { holder = (DownloadableProjectsFromWebHolder)row.getTag(); } String share_text; AllProjectListInfo li = data.get(position); holder.txtPid.setText("ID: " + Integer.toString(li.getId())); holder.txtName.setText(li.getName()); if (li.getShareable()){ share_text = "Public Project"; } else { share_text = "Private Project"; } holder.txtShareable.setText(share_text); return row; } 

Las líneas que están causando el problema:

 35: LayoutInflater inflater = ((Activity)context).getLayoutInflater(); 36: row = inflater.inflate(layoutResourceId, parent, false); 

Aquí la información de LogCat:

Aquí la llamada del adaptador:

 DownloadableProjectsFromWebAdapter adapter = new DownloadableProjectsFromWebAdapter( getBaseContext(), R.layout.all_projects_listview_item, results); 

Y finalmente, la definición de los resultados:

 List<AllProjectListInfo> results 

Ahora, copié este código de otro lugar que donde utilizo un adaptador de encargo. Sin embargo, que uno funciona muy bien. No entiendo por qué este no lo hace.

Cualquier ayuda es apreciada.

Gracias.
