I'm trying to format a string from string.xml to reuse it with several Values. I'm running into some problems as the String should also contain the percentage-symbol which is used by the formatter. I already tried to replace the % symbol by its Unicode presentation but that doesn't seem to work:
<?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 Code:
String value = "25"; String formattedString = context.getResources().getString(R.string.teststring), value); In this example, teststring and teststring2 will produce an error, while teststring3 works fine. What's the correct way to put that % symbol in the xml-string to get "The new value is 25%" as formatted String?

<string name="teststring">The new value if %1$s%%</string> formatted="false" must not be set.

If you are accessing from <string-array/>, then for printing percentage use \u0025.
The percent sign tells the XML processor to look up the entity name in the DTD's list of parameter entities, insert the value of the entity into the DTD in place of the entity reference, and process the value of the entity as part of the DTD.
You can do this by using %% in the printf statement. For example, you can write printf(“10%%”) to have the output appear as 10% on the screen.
String. xml file contains all the strings which will be used frequently in Android project. String. xml file present in the values folder which is sub folder of res folder in project structure.In Android Studio, we have many Views such as TextView,Button,EditText,CheckBox,RadioButton etc.
Use
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="teststring">The new value is %1$s%%</string> </resources> In java
String value = "25"; String formattedString = String.format(getResources().getString(R.string.teststring), value); Log.i("",formattedString); Can you try \%% instead of % ??
Like,
<string name="teststring">The new value is \%%</string> Or
<string formatted="false" name="teststring" >The new value is %</string> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
