UnknownFormatConversionException: Android strings.xml 格式 <![CDATA[ ...%1$... ]]>

Question

我正在尝试在 strings.xml 中使用格式化的 html。所以在 strings.xml 我有以下内容：

<string name="application_start_message" formatted="false">
    <![CDATA[ bla bla bla %1$ bla bla bla %1$.... ]]>
<string name="application_website_url">website.com</string>

后来在我做的代码中：

String string = getString(
    R.string.application_start_message,
    getString(R.string.application_website_url)
);

我得到的运行时异常是：

java.lang.RuntimeException: Unable to start activity 
    ComponentInfo{com.artigile.checkmyphone/
    com.artigile.checkmyphone.MainActivity}: 
    java.util.UnknownFormatConversionException: Conversion: <

有什么想法可以解决这个问题吗？

我不确定这是否是您的问题中的拼写错误，但看起来您正在关闭字符串标签并且您的变量不正确。回车也可能有问题，所以也去掉它。

变化：

<string name="application_start_message" formatted="false">
    <![CDATA[ bla bla bla %1$ bla bla bla %1$.... ]]>

到

<string name="application_start_message" formatted="false"><![CDATA[ bla bla bla %1$s bla bla bla %1$s .... ]]></string>
