更改对话框文本的Android

Question

我有这样一段代码：

private void displayMessage(String message) 
{ 


    LayoutInflater factory = LayoutInflater.from(this); 
    final View deleteDialogView = factory.inflate(R.layout.dialog_confirmation, null); 
    final AlertDialog deleteDialog = new AlertDialog.Builder(this).create(); 
    deleteDialog.setView(deleteDialogView); 
    deleteDialogView.findViewById(R.id.dialog_btn_yes).setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      //your business logic 
      deleteDialog.dismiss(); 
      finish(); 
     } 
    }); 
    deleteDialogView.findViewById(R.id.dialog_btn_no).setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      deleteDialog.dismiss(); 

     } 
    }); 

    deleteDialog.show(); 
} 

我想要做的就是得到的消息参数，并从对话框中的XML布局在TextBox把这个消息。我试过这个：

TextView confirmationTextView = (TextView) findViewById(R.id.order_summary_text_view); 
    confirmationTextView.setText(message); 

但它不起作用。有任何想法吗？ 谢谢！
