According to the answer in English ( here ) and the reference ( here ), put this code in the xml:

<string name="meatShootingMessage">You shot %1$d pounds of meat!</string>

And so in the code:

 int numPoundsMeat = 123;
String strMeatFormat = getResources().getString(R.string.meatShootingMessage);
String strMeatMsg = String.format(strMeatFormat, numPoundsMeat);

EDIT:

Because you can have multiple variables inside a string.xml, they are numbered and typed. The% indicates the number of the variable, indicating the order in which it is to be filled programmatically. $ Sets the type of the variable. As exemplified in the links above, it can be $ s for string, or $ d for a number.
