Tentando pesquisar uma lista de itens usando o texto editável, onde clicar no item pesquisado retornando a posição errada.

Supostamente eu procuro "C" a partir de uma determinada lista, onde o item da lista é o seguinte: "A", "B", "C", "D", "CC", e obtive o resultado correto da pesquisa, mas ao clicar no item de pesquisa, Ele retornando a posição errada do item.

Aqui Edittext addTextChangedListener:

edtSearch.addTextChangedListener(new TextWatcher() {

            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                adapter.getFilter().filter(s);
                adapter.notifyDataSetChanged();

            }

            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {

            }

            public void afterTextChanged(Editable s) {
            }
        });
    }
