EditText does not open the keyboard within the listView

A listView was created within a dialog and I placed in front of each information a EditText , but when I click on EditText to change the information it puts the cursor inside EditText , but not% open the keyboard so I can change the data.

Note: this editText is in a layout , I do not create it in adapter .

Follow the codes.

Dialog that loads the list:

private void dialogMateriais(){
        final View dialogView = inflater.inflate(R.layout.lista_materiais, null);

        android.app.AlertDialog.Builder dialog = new android.app.AlertDialog.Builder(LancamentoActivity.this);
        dialog.setTitle("MATERIAIS");
        dialog.setView(dialogView);

        List<Materiais> listaMaterial = new ArrayList<Materiais>();
        MateriaisDAO materiaisDAO = new MateriaisDAO(LancamentoActivity.this);

        inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
        listView = (ListView) dialogView.findViewById(R.id.listMateriais);

        listMateriais = materiaisDAO.getMateriais(EntradaActivity.numeroOrdem);

        ListarMateriais = new ListaMateriaisAdapter(LancamentoActivity.this, listMateriais);

        listView.setAdapter(ListarMateriais);
        listView.setCacheColorHint(Color.TRANSPARENT);

        dialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        });

        dialog.setNegativeButton("CANCELAR", new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
