format statement in a string resource file

You do not need to use formatted="false" in your XML. You just need to use fully qualified string format markers – %[POSITION]$[TYPE] (where [POSITION] is the attribute position and [TYPE] is the variable type), rather than the short versions, for example %s or %d.

Quote from Android Docs: String Formatting and Styling:

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In this example, the format string has two arguments: %1$s is a
string and %2$d is a decimal integer. You can format the string with
arguments from your application like this:

Resources res = getResources();
String text = res.getString(R.string.welcome_messages, username, mailCount);
