Edittext does not open the keyboard inside the listview

Question

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

Obs: that editText he’s in a layout, I don’t believe him at all adapter.

Follows the codes.

XML who loads the list:

<TableLayout
    android:id="@+id/TableLayout1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:showDividers="middle"

    android:stretchColumns="*"
    android:layout_alignParentTop="true"
    android:layout_alignParentStart="true">

    <TableRow

    </TableRow>

Adapter:

@SuppressLint({ "ViewHolder", "InflateParams" })
public class ListaMateriaisAdapter extends BaseAdapter {

    private LayoutInflater mInflater;
    private List<Materiais> listMateriais;
    private Context context;
    protected LinkedList<Materiais> material;

    public ListaMateriaisAdapter(Context context, List<Materiais> listMateriais)

        //------------------------------------------------------------------------------------------

        View convertView = view;

        view = convertView;

        return view;


    }
}

Dialog who 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();
            }
        });

        dialog.show();
    }
