Here is my custom adapter whose instance called notes i am using in above code.
public class IconAdapter extends BaseAdapter

private Activity activity;

//ImageView imageView;

public IconAdapter(Activity a, ArrayList<HashMap<String,String>> items)
{
activity = a;
listItems = items;
data = items.toArray();
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
pm = a.getPackageManager();
for(int i = 0; i < items.size(); i++)
{
itemChecked.add(i,false);
}
for(int i = 0; i < items.size(); i++)
{
itemSelected.add(i, " ");
}
for(int i = 0; i < items.size(); i++)
{

ctv.add(i,cb);
}
}

}
else
{

Could anybody tell me why i am getting a ClassCastException at reChecked.add(i, sharedPreferences.getString(s, "empty"));.
I mean it's strange that its telling me that i am casting boolean into string but how???? i did not even used boolean anywhere in this code.
Note. - notes.itemSelected is an ArrayList of string type.
Please help.
