ClassCastException: android.widget.LinearLayout $ LayoutParams

Así que obtener este error al ejecutar un adaptador en FinderActivity.class.

public class FinderActivity extends ListActivity { private List<String> itemsearchoptions = Arrays.asList( new String[] { "Search Service Center","Search Showroom", "Area Surveillance", "Nearest OAC Offices" }); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.finder); getListView().setAdapter(new FinderListAdapter(this, this.itemsearchoptions));//cause of error } 

Aquí está My FinderAdapterclass:

• Elemento de lista personalizada para ListView android
• Use locale (ltr / rtl) para gravedad en TextView
• Modificación del diseño del título de diálogo en Android
• addView no funciona
• SetClickable () no funciona en el botón

 public class FinderListAdapter extends BaseAdapter { Context context; LayoutInflater inflater; private int[]icons = { R.drawable.icon_service_center, R.drawable.icon_car_showroom, R.drawable.icon_radar, R.drawable.icon_office }; private List<String>options = null; public FinderListAdapter(Context paramContext, List<String>paramList) { this.context = paramContext; this.options = paramList; this.inflater = LayoutInflater.from(paramContext); } @Override public int getCount() { return this.options.size(); } @Override public Object getItem(int paramInt) { return this.options.get(paramInt); } @Override public long getItemId(int paramInt) { return paramInt; } @Override public View getView(int paramInt, View paramView, ViewGroup paramViewGroup) { String str = (String)this.options.get(paramInt); if(paramView == null) { } else { return paramView; } return paramViewGroup; } public boolean isEmpty() { return (this.options == null)||(this.options.size()==0); } private static class ViewHolder { ImageView finderIcon; TextView finderText; } } 

Utilicé LinearLayout en la lista de artículos

He leído varios problemas similares acerca de este error, pero aún no entiendo completamente el concepto. Así que cualquier ayuda será apreciada. Gracias
