Answer 1

• 您在mSelectedQuote mth。
中获得了onQuote()
• 现在您可以在mSelectedQuote
上获得金额
• 将其传递给showConfirmationAlert（金额）;

• 将其设置为AlertDialog，如下所示 -

  private void showConfirmationAlert(int amount) {
  AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
  builder.setMessage(getResources().getString(R.string.quote_confirm) + amount);
