                items);

您可以尝试

// make temporary array to store your List view value   
 private ArrayList<String> tempArray = new ArrayList();

        @Override
        protected void onListItemClick(ListView l, View v, int position, long id) {

            tempArray.add(items[position].toString());
            String allItems = "";
            for (int i = 0; i < tempArray.size(); i++) {
                allItems = allItems + "\n" + items[position].toString();
            }
            Toast.makeText(v.getContext(), ""+allItems, Toast.LENGTH_SHORT).show();
        }
