AndroidStudio错误与xliff

Question

我正在学习本地化和显示文本，具体取决于设备上的默认语言环境设置。

一行代码出现问题我无法弄清楚原因，因为示例项目具有完全相同的代码而没有任何错误。

的strings.xml

<!--
  Whipped cream topping for the order summary. It will be shown in the format of
  "Add whipped cream? true" or "Add whipped cream? false". [CHAR LIMIT=NONE]
-->
<string name="order_summary_whipped_cream">Add Whipped Cream? 
<xliff:g id="hasWhippedCream" example="true">%b</xliff:g></string>

<!--
  Chocolate topping for the order summary. It will be shown in the format of
  "Add chocolate? true" or "Add chocolate? false". [CHAR LIMIT=NONE]
-->
<string name="order_summary_chocolate">Add Chocolate? 
<xliff:g id="hasChocolate" example="true">%b</xliff:g></string>

MainActivity.js

/**
 * This method creates the string to display
 */
private String createOrderSummary
(String enteredName, int price, boolean hasWhippedCream, boolean hasChocolate)
{
    String orderSummary = getString(R.string.order_summary_name, enteredName)
                 + "\n" + getString(R.string.order_summary_whipped_cream, hasWhippedCream)
                 + "\n" + getString(R.string.order_summary_chocolate, hasChocolate)
                 + "\n" + getString(R.string.order_summary_quantity, quantity)
                 + "\n" + getString(R.string.order_summary_price, price)
                 + "\n" + getString(R.string.thank_you);

    return orderSummary;
}

getString(R.string.order_summary_chocolate, hasChocolate)带有红色下划线并显示this

我真的不明白，为什么第一个字符串order_summary_whipped_cream完全正常，order_summary_chocolate给我这些错误 - 它们是相同的，只有名称不同

希望我不会监督任何明显的事情：/
