撇号前面不带 \

我在 Android 应用程序中定义了一个字符串：

<string name="search_occurs">'{string}' occurs {times}</string>

这给出了错误：撇号前面没有\（在“{string}”中出现了{次}）

我尝试了很多方法来解决这个问题：

<string name="search_occurs">\'{string}\' occurs {times}</string>
<string name="search_occurs">&apos;{string}&apos; occurs {times}</string>
<string name="search_occurs"><![CDATA['{string}' occurs {times}]]></string>
<string name="search_occurs"><![CDATA[\'{string}\' occurs {times}]]></string>

我无法摆脱错误。我缺少什么？

这些都应该根据http://developer.android.com/guide/topics/resources/string-resource.html#FormattingAndStyling http://developer.android.com/guide/topics/resources/string-resource.html#FormattingAndStyling:

<string name="search_occurs">\'{string}\' occurs {times}</string>
<string name="search_occurs">"'{string}' occurs {times}"</string>
