java - 更改对话框文本 Android

Question

我有这段代码:

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();
}

我想要做的是获取消息参数，并将此消息放入对话框的 XML 布局中的 TextBox 中。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!

替换这个

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

与

TextView confirmationTextView = (TextView) deleteDialogView .findViewById(R.id.order_summary_text_view);
