ClassCastException: android.widget.LinearLayout$LayoutParams

So i get this error when executing an adapter in 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 } ``` Here is My FinderAdapterclass: ``` 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; } } ``` I used LinearLayout on the item list I have read several similar problems about this error, but yet to fully understand the concept. So any help will be appreciated. thanks edited : sorry forgot the stacktrace ``` 07-08 15:31:42.380: E/AndroidRuntime(4550): FATAL EXCEPTION: main 07-08 15:31:42.380: E/AndroidRuntime(4550): java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.ListView.measureScrapChild(ListView.java:1166) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.ListView.measureHeightOfChildren(ListView.java:1248) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.ListView.onMeasure(ListView.java:1158) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.view.View.measure(View.java:15525) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4825) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1404) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.LinearLayout.measureVertical(LinearLayout.java:695) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.LinearLayout.onMeasure(LinearLayout.java:588) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.view.View.measure(View.java:15525) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4825) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.widget.FrameLayout.onMeasure(FrameLayout.java:310) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.view.View.measure(View.java:15525) 07-08 15:31:42.380: E/AndroidRuntime(4550): at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:4825) ```
