java.lang.String cannot be cast to android.widget.ListAdapter

Question

I got this error trying to get all items with specific object and store it to my Listview.

Following the codes:

   SimpleDateFormat formatdate = new SimpleDateFormat("MMM. dd, yyyy");
            String selecdate = formatdate.format(date);

            if (eventDates.contains(selecdate)) {
                for (int i = 0; i < eventsList.size(); i++) {
                    HashMap<String, Object> obj = (HashMap<String, Object>) adapter.getItem(i);
                    ListAdapter list = (ListAdapter) obj.get("eventtitle");
                    myList.setAdapter(list);
                }
            }
            else {
                myList.setAdapter(null);

            }

java.lang.String cannot be cast to android.widget.ListAdapter

This line is saying that your obj.get("eventtitle"); is returning String as a value not a ListAdapter

As docs says

public abstract Object getItem (int position)
Get the data item associated with the specified position in the data set.

So might be your dataSet is of String rather than ListAdapter
