strings.xml中的百分比符号

标签: android xml string format

我试图从string.xml格式化一个字符串,以便将其重用于多个值。我遇到了一些问题,因为String还应该包含格式化程序使用的百分比符号。我已经尝试用它的unicode表示替换%符号,但这似乎不起作用:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="teststring">The new value is %1$s%</string>
    <string name="teststring2">The new value is %1$s\u0025</string>
    <string name="teststring3">The new value is %1$s</string>
</resources>

Java代码:

String value = "25";
String formattedString = context.getResources().getString(R.string.teststring), value);

在这个例子中。 teststring和teststring2将产生错误,而teststring3工作正常。什么是正确的方法将%符号放在xml-string中以获得“新值为25%”作为格式化字符串?

感谢您的帮助。

- EDIT-- 谢谢您的帮助。正确的答案是

<string name="teststring">The new value if %1$s%%</string>

formatted =“false”不得设置。

使用

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="teststring">The new value is %1$s%%</string>

</resources>

在java中

String value = "25";
String formattedString =
    String.format(getResources().getString(R.string.teststring), value);
Log.i("",formattedString);

答案 1 :(得分:5)

你可以试试\%%而不是%??

像,

<string name="teststring">The new value is \%%</string>

或者

<string formatted="false" name="teststring" >The new value is %</string>

答案 2 :(得分:5)

试试这个

<string  name="teststring"> The new value is %1$s %% </string>

答案 3 :(得分:1)

检查一下,

<string name="teststring">The new value is %1$s %%</string>

String value = "25";
String formattedString = this.getResources().getString(R.string.teststring, mPageNumber);

答案 4 :(得分:1)

String value = "25";

String formattedString = "The new value is " + value + (char) 0x0025;

如果现在是Log.d(TAG,formattedString);它会记录

The new value is 25%

答案 5 :(得分:0)

像这样使用:

String str = context.getResources().getString(R.string.teststring);
String formattedString = String.format(str, value);

答案 6 :(得分:0)

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <string name="offerString">The new value is %1$s%% %2$s</string>
    </resources>

String offerOnHdfc = "25";
String formattedString = String.format(getResources().getString(R.string.offerString), offerOnHdfc);
Log.i("",formattedString);
