Use string format arguments in Android layout xml file [duplicate]

Answer 1

No, there is no means of applying a value to the format from a layout file -- only in Java. Sorry!

UPDATE: You can now use data binding for this — see the duplicate question.

Answer 2

For Example In strings.xml
You have %d unread messages

In Your Java code
String message = getString(R.string.unread_messages, 10);
