setContentView, spinner custom alertdialog in android

Question

I want to create a custom alertdialog with Spinner .So i used the following code.

AlertDialog.Builder alertDialog = new AlertDialog.Builder(ActivityThu.this);

    alertDialog.setTitle("Thêm khoản thu");
    //final LayoutInflater layoutInflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   // final  View dialogView = layoutInflater.inflate(R.layout.thu_thong_bao_them, null);//Tạo dialogview từ layout thông báo
    View dialogView = getLayoutInflater().inflate(R.layout.thu_thong_bao_them, null);
    spinner=(Spinner)dialogView.findViewById(R.id.spdanhmuc_them);

    MyDatabaseHelper db = new MyDatabaseHelper(getApplicationContext());

    List<String> lables = db.Load_danhmucthu();

    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, lables);

    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    spinner.setAdapter(dataAdapter);

    alertDialog.setView(dialogView);// đặt dialogview vào alertdialog
    alertDialog.setIcon(R.drawable.add48x48);//đặt icon

    alertDialog.setPositiveButton("Thêm",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {


                    }

            });

    alertDialog.setNegativeButton("Hủy",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                }
            });

    alertDialog.show();
