setContentView、androidのスピナーカスタムアラートダイアログ

Question

Spinnerでカスタムアラートダイアログを作成したいのですが、次のコードを使用しました。 DialogAlertため

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();
