What is the error (Edittext filter and search on ListView )?

Question

Android

When typing text in the EditText, the ArrayAdapter text is searched and filtered.

@Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                listView.setVisibility(View.VISIBLE);
                adapter.getFilter().filter(charSequence.toString());

                if(adapter.getCount()==1){
                                        mBashlangic.setText(adapter.getItem(0));
                }
            }

mBashlangic(EditText). Why does the program freeze?
