Answer 1

• 您会在onQuote()获得mSelectedQuote 。
• 现在您可以在mSelectedQuote上获取金额
• 将其传递给showConfirmationAlert（amount）;

• 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);
