If you need to format your string using string. Format (string, object...), you can put the format parameter in your string. See the following example:

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

In this example, the formatted string has two parameters, % 1 $ S is a string % 2 $ D is a floating point number, you canProgramFormat the string according to the parameters in the following method:

Resources res = getresources ();

String text = string. Format (res. getstring (R. String. welcome_messages), username, mailcount );
