Próbuję przeszukać elementy listview używając edittext, gdzie klikamy na wyszukiwany element zwracając błędną pozycję.

Przypuszczam, że przeszukam „C” z podanej listy, w której pozycja listy jest następująca „A”, „B”, „C”, „D”, „CC”, i uzyskałem prawidłowy wynik wyszukiwania, ale raz kliknąłem element wyszukiwania Zwraca złą pozycję pozycji.

Tutaj 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) {
            }
        });
    }
