Row gets duplicated after delete from ListView

Question

I know there are already a lot of questions pertaining to this same issue.

Mine looks a bit weird! I have a custom adapter for ListView where I pass an ArrayList of a Model. I have a Context Menu set for this List where on clicking delete, I need to delete the row from ListView (refreshing then and there).

I am calling xxxxx.remove(info.position) and then listadapter.notifyDataSetChanged(), but it duplicates the last row that was present in the ListView.

Here's the code:

Adapter for ListView:

class MyAdapter extends ArrayAdapter {

private final Context context;
private final ArrayList<ListModel> itemsArrayList;

public MyAdapter(Context context, ArrayList<ListModel> itemsArrayList) {

    super(context, R.layout.viewlistitems, itemsArrayList);
    this.context = context;
    this.itemsArrayList = itemsArrayList;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View rowView = null;

    if (convertView == null) {

    LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    //Get rowView from inflater
    rowView = inflater.inflate(R.layout.viewlistitems, parent, false);
    }
    else
        rowView = convertView;

    // 3. Get the two text view from the rowView
    TextView listNameView = (TextView) rowView.findViewById(R.id.listName);

    listNameView.setTypeface(ViewListActivity.segoe);
    listDateView.setTypeface(ViewListActivity.openSansLightIt);

    String listName1 = itemsArrayList.get(position).getListName();
    String listName2 = listName1.substring(0,1).toUpperCase() + listName1.substring(1);


    listNameView.setText(listName2);

    return rowView;
}

}

ContextMenu:

public void onCreateContextMenu(ContextMenu menu, View v,
        ContextMenuInfo menuInfo) {
      if (v.getId()==R.id.ListView01) {
        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)menuInfo;
        menu.setHeaderTitle(todoItems.get(info.position).getListName());
        String[] menuItems = {"Delete"};
        for (int i = 0; i<menuItems.length; i++) {
          menu.add(Menu.NONE, i, i, menuItems[i]);
        }
      }
    }

public boolean onContextItemSelected(MenuItem item) {
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item
            .getMenuInfo();

    if(item.getTitle().equals("Delete")) {
    Toast.makeText(this,
            todoItems.get(info.position).getListName() + " deleted!",
            Toast.LENGTH_SHORT).show();

    todoItems.remove(info.position);

    //newList.invalidateViews();
    adapter.notifyDataSetChanged();

    }
     return true;
    }

Unable to fix this bug since 1 day! Any idea why this could be happening or what's causing it?

Many thanks!

Alright, I finally resolved this. I used notifyDataSetInvalidated() to invalidate the current adapter, and set a new adapter with my modified list. Worked fine.
